Background

This is my Leica IIIC rangefinder camera made in Wetzlar, West Germany. It uses the standard 35mm perforated film with frame size of 24 × 36mm. My dad bought this IIIC in 1949 when he worked for the US Navy on Guam. It came with a 5cm ƒ/2.0 Summitar lens. He had owned an American-made Perfex 35mm camera during the war years but had wanted a Leica for a long time. During World War II, a few Leicas were exported to the Allies via Sweden, but they were reserved for special uses (spies or well-placed generals?).

After the war, one of the ways a war-ravaged Germany began to rebuild its economy was to export precision optical equipment, such as the famous Leica cameras. Leica's advertising emphasized excellence and sophistication. My dad took the opportunity of low prices at the post exchange on Guam to buy this body and lens. As I recall, he said they cost $150. He used this little Leica for many years, taking family photographs when we lived in Greece and southeast Asia in the 1950s and 1960s. I used it in the 1970s and 1980s and still do.

Operation

On modern standards, this camera is a bit fiddly to use. First the viewfinder has two windows. The way I use it is to first look through the right finder, which shows the complete scene covered by the 50mm lens. If I like the scene, I shift my eye to the left window and focus on the object that is most important. By the way, it is a remarkably accurate focus arrangement considering the short base length. Then I shift back to the right window, do the final framing, and take the picture. Really, it is easier and faster in practice than to describe in text.

Instructions for trimming film before loading

Second, the film needs to be trimmed with scissors to have a long tongue before you insert it in the take-up spool. Then you slide both the 35mm cartridge and take-up spool into the body from the bottom. Leica once sold a trimming guide, but you do not need it. Just use your Swiss Army knife to trim about 8 or 10 cm from the tongue, and it will work. Once loaded, turn the rewind knob gently to remove slack. Then, when you advance the film, make sure the rewind knob is turning in the opposite direction to be certain that the film is truly advancing. Again, it is easier to do than to describe. I carry a spare take-up spool with me, but I have never lost one.

As the photographs show, the camera has almost watchmaker precision in the fittings. The chrome on mine is pitted because in the early post-war era, chromium was hard to buy, and many German cameras had poor plating.

Lenses and filters

From Popular Photography, approx. 1950

With permission from The Online Darkroom.

Leica marketed lenses ranging from 21 to 400 mm, all the best quality available at the time. Oddly, my father never bought any more lenses.

My dad's IIIC came with a 5cm ƒ/2.0 Summitar lens (the prestige lens as opposed to the less expensive 5cm ƒ/3.5 Elmar). Mine is the Type 1 version with 10 aperture blades. The Summitar was in production from 1939 to 1953. It was designed by E. Leitz's genius lens designer, Max Berek, in 1937. The war-time production lenses were uncoated, but Leitz applied anti-reflection coating from 1946 on. The construction was a complicated design of 7 elements in 4 groups. It must have taken a heroic effort to compute the ray paths by human computers using mechanical calculators and trigonometry tables. The central sharpness is superb, but the edges fall off, and there is distinct field curvature. This can be used creatively, and regardless, "sharpness" is not normally the factor that makes a photograph successful.

A few years ago, Sherry Krauter in New York cleaned and checked the Summitar lens for me. Mine is pristine and never suffered the scratches in the soft coating that plague so many 1940s lenses (old-time photographers cleaned their lenses with their neckties).

These older Leica bodies have a screw mount for the lenses. The thread is 39mm × 26 turns-per-inch or threads-per-inch (tpi). This was a Whitworth threading standard, which was common in microscope manufacture in the early 20th century. German, English, and Japanese companies made hundreds of different lenses for this 39mm mount. Focal lengths other than 50mm require an auxiliary viewfinder to show the correct frame. Soviet companies made lenses for 39 × 1mm, but this was close enough to usually fit on the Leitz bodies. The Japanese company, Canon, continued to make superb thread-mount lenses up through the 1970s, when they finally discontinued their excellent thread-mount rangefinder S7 cameras. Note that this is a different 39mm than the 39 × 0.75 thread used for large-format Copal 1 and many other shutters. And it is different than the 39F pitch (39 × 0.5) used for 39mm filters that screw into the front of many Leica lenses. Confusing? Yes, of course!

The shutter in my IIIC body had been troublesome for over a decade, but Don Goldberg (known as DAG) in Wisconsin did a fantastic job overhauling it mid-2017. This is the main roller, on which Mr. Goldberg marked the areas that were badly worn. He replaced it with a new-old-stock main roller, the genuine Leica part. For how many other consumer products that are seven decades old can you still get factory replacement parts (possibly some fine watches or Rolls Royce motorcars?)?

The Summitar lens requires filters with a unique 36mm tapered thread. These were known as Type L filters (see Appendix 1 below). When I used filters on my Nepal trip, I had Leitz Series VI filters and a Tiffen 606 retaining ring (see Appendix 2). It is a bit clumsy but manageable, and the series filters will fit other lenses with the appropriate adapter rings. A polarizer is the most clumsy, but Leica made a brilliant fold-out polarizer just for this task (model 13352). I finally bought genuine Summitar yellow, dark yellow, and green filters, which are faster to handle than the series filters and do not block as much of the view through the viewfinder.

As for a hood, the rectangle folding unit known as a SOOPD fits over type L filters and causes minimal blocking of the view through the viewfinders. 

The Summitar lens is a bit quirky. My example (and maybe all of them?) has a lot of field curvature, so the edges of a flat object will be fuzzy. But a typical scene with the subject near the center has smooth out of focus area away from the central subject. 

Areas outside the zone of focus look smooth and innocuous. This out-of-focus appearance is known as bokeh. Thirty years ago, almost no one thought about it, but now, "photographers" are obsessed with the topic (even though most of them just consider anything out of focus to be bokeh). The newer Type 2 and Type 4 50mm ƒ/2.0 Summicron lenses for my Leica M2 body are "better", but I rather like the old Summitar. It feels good to have my dad's camera in operation again. He would be pleased.

For a trip to Nepal in October of 2017, I decided to use this little IIIC with black and white film and skip the obligatory digital imaging device entirely. It was a great success. Many Nepalis were amazed that I was using a mechanical camera almost 70 years old. It was a tension-breaker to let people look through the viewfinder, but I had to explain that there was no LCD screen for them to see the results. Surprisingly, some of the camera stores in the Thamel area (the main tourist zone) of Kathmandu still stock fresh Ilford and Fuji film in 35mm size. But you probably could not find any 120 or large format film. These examples are on TMax 100 film, developed by Praus Productions in Rochester, New York. I had only used TMax 100 once before and I'm impressed by the fine grain. Nice stuff. To measure exposure, I used a Gossen Luna Pro Digital meter, usually in reflected mode but sometimes in incident mode.

Nepal is a fabulous photographic destination. The people are friendly and welcoming. The country is developing and changing quickly. Go soon to see remnants of an earlier era before they are torn up and replaced with the new commercial world. The same warning applies to Cuba: Go before the developers pillage and ruin it, especially if American developers ever move in.

Summary

A few reasons to buy one of these ltm Leicas:

1. As time goes on, the remaining stock of these thread mount Leicas will be more and more beat up and will diminish in total number.

2. They will be repairable in the future.

3. They don't make them like this any more. Definitely not!

4. They will be usable as long as 35mm perforated film is made and sold.

5. You will enjoy occasionally using one as a substitute for a more sophisticated newer 35mm camera or digital unit.

6. These ltm Leicas are compact and great travel cameras, especially with the collapsible Elmar lens.

7. They are technologically elegant.

8. People stop to admire it when you are using a ltm Leica. It can be an ice-breaker.

9. It is definitely not a spray and pray photon capture device: you need to think with one of them and know a bit about what you are doing (i.e., you can't just push a button).

10. They are unlikely to depreciate.

11. Thread-mount lenses can be used on modern digital cameras.

12 The lenses are appreciating in price, especially for clean examples without fungus, scratches, or haze.

These little Leica thread-mount cameras are still available at reasonable acceptable prices. They are fun to use and have a precision feel that most modern cameras do not replicate (other than Leica M film bodies, which, as of 2022, are still in production). Just go buy one and return to the basics of photography. I know your creativity will blossom.

For an earlier article about how I have used Leica cameras to record urban decay, click this link. 

Mike Johnston, former editor of Camera & Darkroom magazine and now author of The Online Photographer, wrote an excellent article in 1992 about Leicaphilia. He also wrote about The Leica as a Teacher. "A year with a single Leica and a single lens, looking at light and ignoring color, will teach you as much about actually seeing photographs as three years in any photo school, and as much as ten or fifteen years (or more) of mucking about buying and selling and shopping for gear like the average hobbyist."

35MMC has a useful article titled 7 Reasons You Should Own a Thread Mount Leica. I agree with the author that these cameras slow you down and make you think. You just can't spray and pray and then doodle around with Lightroom for weeks culling files, doing the "workflow," and hoping that you might have "shot" a meaningful photograph. Film does not work that way.

Johnny Martyr wrote a detailed review of the Leica IIIC, titled Tempered Indulgence. Also, check his review of the Summitar lens.

Phoblogger has an interesting interview with the manager of Richard Photo Lab (Los Angeles, California) about how film most definitely is not dead and is reviving among many age and skill groups.

Andrew Yue wrote a nice introduction to the Leica thread-mount cameras titled, "- Leica Screw Mount Cameras - the 1930's through the 1950's -"

Update 2019

I bought a Canon 50mm ƒ/1.4 ltm lens and have had very nice results with it.  Click the link to see examples. I also have a 50mm ƒ/2 Jupiter-8 lens from the Soviet Union.

 

Appendix 1, Summitar Filters

The Leitz Summitar used a unique tapered 36mm filter thread. As far as I know, only Leitz and Walz offered this size. This note from the Leica Users Group (LUG) by Marc James Small describes the Leitz filters:

In any event, here is the best listing I can produce for the Summitar filters.  These were known at Wetzlar as L filters (by comparison, the E39 range were O filters).

Filters which only have a catalogue code-word and not a catalogue number did not survive into production to 1954, the first year for the universal use of the numbers.  Many of the 

Summitar filters had dropped out of the catalogues by 1960 and all were gone from the Leitz catalogue by 1962.

If you are a Summitar user, buy the genuine filters when you see examples in good condition. 

Appendix 2, Series Filters

The most comprehensive description of series filters and the various adapter rings made for hundreds of lenses is from photographer Robert Allen Kautz in Vermont. 

• Summitar adapter: Tiffen model 606
• Jupiter-8 lens (40.5mm thread): Tiffen 602 

40.5 mm was common on many German lenses in the mid-1950s, and you can find 40.5mm filters that screw into the lens directly. Beware that Tiffen, Ednalite, and Enteco adapter numbers are different (Confusing? Of course!). 

Kagbeni: Gateway to the Kingdom of Lo (Part 2)

Kagbeni is an ancient trading city perched on a plateau overlooking the Kali Gandaki River in north central Nepal. For centuries, Kagbeni thrived in the salt trade. Caravans of human porters or goats (really) carried salt south from Tibet en route to India. On the return, the caravans brought back rice and other goods from the lowlands. The introduction of manufactured salt containing iodine largely ended the salt trade, but I am not sure of the date. However, black, rose, and white Tibetian salt are now sold in gourmet stores around the world, so some degree of the salt trade has revived (although some of this new salt trade goes through China, therefore not benefiting Kagbeni at all). In the United States, iodine was first added to salt in 1924. Iodine deficiency is a leading preventable cause of intellectual and developmental disabilities, or mental retardation (from Wikipedia). Lack of iodine also caused many people to develop goiters (swelling of the thyroid gland).

The geology here is spectacular. The Kali Gandaki winds its way south across a gravel-filled valley, meandering and crossing over and over. The trail crossed some of the streams on temporary wooden bridges, and in other places follows along the shore above the valley bed. In the second photograph, look at the talus slopes (rock debris) tumbling down the valleys and into the Kali Gandaki's flood plain. These talus slopes are an example of erosion caused by gravity flow, with possibly some assistance during the winter by water transport. This is an arid climate, but even minor rainfall may help lubricate rocks and make the slopes less stable.

Many Nepalis come to the river bed to look for ammonites, called Saligram in Nepali. They are Upper Jurassic age, about the age of the opening of the Atlantic Ocean. These demonstrate that sediments in the Himalaya were once seabed and that the uplift of the Himalaya is younger than Jurassic. The uplift was caused by the collision of the Indian and Asian continental plates, which is ongoing. As long as the himalaya are uplifting, there will be an almost endless supply of sediment to be carried down the rivers, and, eventually, into the Ganges. The Ganges eventually joins the Brahmaputra, which jointly form the massive Ganges-Brahmaputra Delta, which protrudes into the Bay of Bengal.

We rough and tough trekkers (wimps) were tired after a day walking north along the river from the town of Jomsom. This was the Trekkers Inn near the south entrance to town. It was clean, cheerful, and comfortable.

Late afternoon, the wind blows mercilessly across the river valley, carrying clouds of sand and dust. Best to hang out in the inn and drink a tea. The walls around the older houses were a protection against the wind. The wood neatly piled along the rooftop are a traditional demonstration of wealth. In the past, the wood was vital to heating and cooking in winter. Today, many houses use kerosene stoves, so the wood is symbolic or maybe just a decoration. The air is so dry, the wood does not rot.

This little fellow welcomed travelers and was a symbol of good fortune. He apparently needs repair on a regular basis. It is a hard job being out in the weather.

Narrow alleys take you to courtyards and an occasional stupa. Again, note the wood stacked along the roof parapets.

 

The Kag Chode Thupten Samphel Ling Monastery at the edge of town is a fascinating mixture of ancient and 20th century buildings. Some of the books neatly stored in silk wrappers are hundreds of years old. A huge Tibetan Massif protects the grounds. During the day, he is pretty mellow and sleeps in the sun. But at night, he roams the grounds and eats tourists (and possibly goats and cows).

Late afternoon, the goats come marching through. Poop overload, just be sure you are not in the way. This was late October, and the goats were heading south, I presume to markets in south Nepal or India.

After a night in Kagbeni, we proceeded north into Mustang. We had to show our trekking permits to policemen at a guard station at the north end of town.

The Deepest Canyon: the Kali Gandaki River, Nepal

Dear readers, I am trying to catch up with some overdue projects. One of these is to summarize my 2011 trip to the Mustang region of Nepal. I listed some of the waypoints of this trip in a 2011 post. This post will be about the fantastic walk down the Kali Gandaki River in west central Nepal.

The Kali Gandaki River makes a great gash through the Himalaya. The river's headwaters are in the Mustang region near the border with Tibet. It then flows south through Mustang (formerly a kingdom and subject of a future post) through gorges and valleys. South of the town of Jomsom, it cuts through the mountains again. "The river then flows southward through a steep gorge known as the Kali Gandaki Gorge, or Andha Galchi, between the mountains Dhaulagiri, elevation 8,167 metres (26,795 ft) to the west and Annapurna I, elevation 8,091 metres (26,545 ft) to the east. If one measures the depth of a canyon by the difference between the river height and the heights of the highest peaks on either side, this gorge is the world's deepest." (from Wikipedia). Eventually, the river flows into the Ganges, after flowing over an immense megafan, comprising sediments eroded from the rapidly uplifting Himalaya.

My 2011 waypoints along the Kali Gandaki valley, with elevations in m above sea level. (Maps drawn with ESRI ArcMap software.)

In decades past, many Europeans and Americans walked down the great gorge when they made the trek around Annapurna (one of the world's great walks). But in the early 2000s, a rough road was cut along the right (west) bank of the Kali Gandaki, and an airport was built in Jomsom. This led to many tourists either flying out or taking a bus. As of 2011, the trekkers' route was becoming underused, and some inns and restaurants had closed.

Jomsom before landing at JMO.

Before my October 2011 walk downstream, I had just completed the trek through Mustang to Lo Manthang, the ancient walled capital of the Kingdom of Lo. My friends flew back to Pokhara from Jomsom Airport (IATA: JMO), which is at elevation of 8,976 feet (2,736 m). The airport often suffers bad weather and has been the site of several crashes. Most of the town is located on a plateau above the river valley.

For my walk down the gorge, I was accompanied by a friendly young Sherpa, Pasang, who had been with us all the way through Mustang. There was also a porter, Rahm, to carry my duffel bag, although we really did not need his services. Regardless, these fellows depend on tourists for income, and I appreciate their hard work.

Day 1. This took us from 2800-m high desert plain into a scrub terrain with juniper and pine that looked like the US southwest or Greece. The first town south of Jomsom was Marpha, which is in an apple-growing region. There is a well-known distillery as well as an ancient monastery.

Approaching Tukuche, the trail hugs the edge of the broad gravel riverbed, occasionally crossing tributaries on rickety wood walkways. One option is to follow a path along the gravel riverbed, but you are exposed to blowing dust. The route along the west side of the valley is better, and, in many areas, the main road.

The High Plains Inn - Dutch Bakery in Tukuche is a great lunch stop, and the hungry trekker is obligated to eat an apple strudel (or two) topped off with an espresso. The route down the Kali Gandaki has  plenty of inns and rest stops like this, so really, this is an easy trek.

We met a lady who was sorting beans that had been drying on a roof. I wonder if they cook red beans and rice? In this area, many villagers stay for the winter, so they carefully stock supplies. But further north in Mustang, the weather is more severe, and villagers migrate to lower altitude areas or to India to find winter work.

Our destination for the night was Larjung, another tidy little town. It is still 2,500 m high, and the villagers were drying corn and other items in preparation for winter.

This was the Riverside Lodge, a nice place with hot water in the shower. Part of the roof was flat, providing a surface to dry corn. The tree had apples. The restaurant was good. Happy chickens lived in a coop and clucked around.

Day 2. The next morning, we continued down stone paths towards the gravel bed of a tributary that enters the Kali Gandaki. The road make a long detour upstream, but the walking path crosses the gravel bed.  In spring, the walking path must be impassable, and pedestrians need to follow the road. As you can see, at this elevation, the flora had changed to alpine forests with pines, much like Austria.

We continued downstream to the village of Kalopani, still at an elevation of 2,500 m.

This is one of these very interesting and somewhat swaying steel suspension bridges that cross the Kali Gandaki.

Looming above you to the east is the might peak of Annapurna, Annapurna I is the tenth highest mountain in the world at 8,091 m above sea level. Annapurna is an especially dangerous peak for climbers, with a death to summit ratio of 32 percent.

I was glad to be well below in the valley. We descended steeply during the afternoon along the river valley to the hamlet of Ghasa at only 1950 m elevation. The Eagle Rest Guest House & Garden Restaurant was really nice, and finally we saw other trekkers. Before this stop, we saw very few Americans or Europeans. My green day pack contained water, camera, and personal items. The porter carried my red duffel, which held clothing, sleeping bag (not needed here), and bulky things.

This fellow with the wet nose wanted a room, also.

Day 3. We continued downhill towards Thalpa, about 1800 m elevation. The valley walls towered above us. Yours truly, of course, looked his dorky best. I had been above 3000 m for two weeks, and here at "low altitude" the air felt so thick.

A tributary, the Rupse Chhahara, plunges down the mountain. The bus trundles through the water. Some of the year, the route must be impassable. It takes a degree of bravery to take one of these busses. My anthropologist friend said every now and then, a bus falls off the mountain. By now, we had dropped to 1590m elevation.

Dana, at 1461m has some old stone buildings with Tibetian-style windows of beautiful craftsmanship. The town has a guest house and a bus stop.

The valley near Dana is bucolic, and the footpath takes you along ancient stone walkways through the farms.

By midday, we reached Tatopani, at 1190 m. We descended steeply into broad leaf forest and finally into jungle.

On recommendation from my friend, I checked into the Dhaulagiri Lodge and Restaurant, near the southern end of Tatopani. Nice place, with an excellent restaurant. They put me into my own little cabin, and right outside my room were bamboo and banana plants and geckoes (no obvious snakes). I paid the porter, Rahm, and he headed back upriver.

Tatopani is famous for the hot spring, and I soaked with chubby Japanese visitors.

All in all, this has been a spectacular trek, a passage through geologic history as well as botanic altitude zones.

Change is coming. The villages here are still poor, but they have electricity and serve hikers who are making the Annapurna loop trek. Most lodges have rooms with private bath, but hot water is still rare. The towns have schools and health clinics. The road is a treacherous dirt and rock trail carved out of the mountain-side. As of 2011, busses and jeeps regularly broke down or fell off, squashing their occupants.

Day 4. Two Germans that we met in the lodge, Pasang, and I chartered a taxi take us to Pokkhara, from where we flew to Kathmandu. The taxi took 5 hours as opposed to 8+ on the public bus (which often breaks down). It was a tiny car, and we were rather squashed. And we had to stop a few times to let the goats move off the road. (Note: this was Oct. 21, 2011, and we learned late in the day that Colonel Muammar Mohammed Abu Minyar Gaddafi, the long-term dictator and butcher of Libya, had been killed by Libyan militiamen.)
