The Cosina CT-1A is a manual-focus 35mm SLR from Cosina.[1] It accepts K mount type lenses. It is nearly the same as the Cosina CT-1 but replaces that model's analog meter needle with a match-LED exposure indicator ( + O - ) at the side of the viewfinder. This also necessitated the use of two LR44 or SR44 batteries, rather than the single mercury cell of the earlier model.

It has a vertically-traveling focal plane shutter with speeds from 1s to 1/1000 with B. Flash sync is at 1/125 a sec. The self-timer is mechanical with a delay of approx 10 sec. It features a open-aperture TTL metering in a center-weighted pattern, utilizing two CdS cells. The meter has a range of 3 to 18 EV at (ASA 100). Capable of using film speeds from 25 to 1600 ASA. The film transport uses a film advance lever and a rewind crank.

Cosina's CT1G model was essentially the same camera but omitting the self-timer function (and was at one point included in a combined manual). Cosina's followup the CT1 Super upgraded the top shutter speed to 1/2000 second, but closely resembles the CT-1A.

Notes

  1. It appears to have been announced in late 1980, and was going on sale by the time of this news item about Cosina introductions in the April 1981 Popular Photography, pg. 222, via Google Books.
