Background
The 135mm focal length was popular through much of the 20th century. Leica and Zeiss sold 135mm lenses starting in the 1930s. During the single-lens-reflex boom of the 1960s and 1970s, all the Japanese companies made 135 lenses for their respective cameras. Often, that was the second lens a budding photographer bought, until the marketers convinced amateurs that they "needed" the off-brand 80-210mm zoom lenses (i.e., more profit margin for camera stores).

Notes: 1. Sources: “A History of Pentax” articles by W. L. Fadner in Shutterbug (1988) 2. U.S. cameras had the Honeywell name and logo on the prism. International models were labeled with the Asahi name and logo. Many servicemen brought Asahi models back from Vietnam. |

The 35mm ƒ/3.5 Super-Takumar or SMC Takumar is another under-appreciated gem. I tested my bargain 35 around town and at the Tomato Place.

Coating
Despite the obvious benefits of a hood, most point-and-shoot cameras of the 1980s and 1990s did not have any way to attach a hood for two reasons: 1. Users had been told that multi-coating negated the need for a hood (wrong); 2. Casual users would not use them even if supplied (lazy or uncaring).
