The GAS Attack
Yes, yes, I know, I utterly lack discipline. I suffered an explosive bout of GAS (Gear Acquisition Syndrome) and bought an ultra-wide lens for my Hasselblad 501CM camera. I already owned a 50mm ƒ/4 Distagon lens, but sometimes I wanted to be closer or be right inside the scene and capture it.
My 50mm lens provides a diagonal view similar to a 27mm in the 35mm format. This new 40 provides a 22mm view (note, the frame proportions are not the same, square versus rectangle, so these are approximations only). I have already learned that this 40 is hard to use and need to take advantage of its unusually wide view.
Zeiss made four generations of 40mm lenses to fit Hasselblad V bodies. These are the mid-20th century mechanical bodies that use 120 film, usually for the 6×6 format. It is difficult to find production years, but this is an approximate summary of the 40mm lenses:
Distagon 40mm ƒ/4 C with Bayonet 104 filter. This is a huge optic, computed in the 1960s. It was a pioneering retrofocus lens at the time. Single coat 1967-1973, multi-coated T* 1974-1982. These C lenses are said to be front heavy and hard to focus. Zeiss also made versions of this 40 for Rollei SL66 and Rollei SLX/6006.
Distagon ƒ/4 40 mm CF (FLE). Newly computer smaller lens with floating element, 93mm drop-in filters, 1982-1998.
Distagon ƒ/4 40 mm CFE (FLE). Newer style body (see the pictures above), 1998-2003.
Distagon ƒ/4 40 mm CFE (IF FLE). Internal focus, final 40mm model (rare and expensive), designed for use with digital backs, 2003-?
Hasselblad also offered a 38mm Biogon type of lens permanently mounted in a special body, the SWC. This is said to be the least distortion super wide lens. I was tempted but wanted a lens that would mount on my 501CM body and let me frame through the viewfinder.
My 40mm CFE model accepts 93mm unthreaded filters, which are held in place by a retaining ring. These are the same concept as traditional series filters. But the 93mm units are rare, rare, rare. My lens came with a clear UV filter. Amazingly, I saw an orange 93 for sale at KEH and grabbed it instantly. Yellow and green 93s are unobtanium. If you buy a used 40mm lens, make sure that it includes the retaining ring/shade, the items that hold a 93 filter in place.

Upper ring adjusts the internal floating element |
My lens has an internal floating element, meaning one that can be shifted separately from the other elements. A focus dial lets the user select the subject distance. This is designed to improve optical quality for close-ups. Most of my pictures are of mid- or far distance, so I have only needed to adjust this extra setting a few times. The procedure for close subjects:
- Focus on the intended subject.
- Adjust the floating element ring to see the best sharpness across the frame.
- Readjust the main focus ring. But it may not need to be moved at all.
Focus with ultra wide lenses can be tricky with any reflex camera. But with my Acute Matte viewfinder screen, focus pops in and out precisely. I do not know how the view would be with the older, dimmer Hasselblad screens. Minolta developed the technology for these screens, and Minolta camera viewfinders were known for being easy to use. As far as I know, new Acute Matte screens are no longer available, and used screens in good condition sell for around $500 now. Other companies offered brighter screens for the Hasselblad, (e.g., Beattie IntenScreen, BrightScreen) but the consensus is the Acute Mattes are the best.

Summary
Well, I am happy with my new/old 40mm Distagon. Optically, this 40 is amazing. I see minimal light falloff at the corners of the frame, and the resolution is fine center to edge. I can focus it without hunting back and forth with both the 501's fold-up finder or the prism finder. This lens is wonderful with color film (stand by for more examples soon).
It takes practice to use a lens this wide well. It helps to be right inside your scene. In the same way, I had to learn how to get the best effects from the ultra-wide 30mm lens on my friend's Hasselblad XPan panoramic camera. I also recently bought a 21mm Zeiss Biogon lens for the 35mm Leica - this will require a learning curve, too.
But this 40mm Hasselblad lens is a heavy chunk in my camera bag. I bought a small LowePro backpack to experiment carrying all this stuff. And I have yet to find 93mm yellow or green filters.
More examples to follow. But no more equipment GAS. I promise.......
