    The metering system is a lot better than in older Zeniths with selenium meter, but still needs to be checked before you can be sure if it works properly.

    Jamming iris is a common problem with Russian automatic diaphragm lenses. You have to check if it stops down properly when you push the shutter button half way down.

    Nick,
    To check the meter. Set the camera to 110 GOST. Set the shutter to 1/125. On a bright sunny day, an average scene should meter about f/16.

    Welcome to the gang. I also have a Zenit slr.

    GOST is the film speed system used in the Soviet Union

    ****** I just checked my Zenit 122 (my newer Zenit). The film sensistivity dial (under the rewind knob) reads ISO-GOST. There is a slight difference between ISO speeds and GOST speeds but it probably can be ignored. The progression of film speed numerals on this camera leads me to believe that Zenit is now using "ASA" (ISO) numbers. BTW, ISO ("ASA") 125 is equal to GOST 110---neither of which has a number setting on the Zenit I have in front of me.

    Yes, Nick.

    A DIN setting of 22 should be equivalent to ISO 125, GOST 110.
    The hint I gave earlier is the Sunny 16 rule. USe the "ASA" as a shutter speed, set the f/stop to f/16 on a bright sunny day, and your exposure shall be pretty much dead on. You can use that "rule" for a quick/rough check of the meter's accuracy.

    Also, Nick; On slower shutter speeds (ca. 1/25 and slower, you must be sure to hold the shutter release down until after you hear the shutter complete its cycle. The lens aperture is connected to the shutter release on these cameras. If you let up too soon, the aperture will begin opening before the exposure has been completely made.

    These cameras are not the most up-to-date technology; but they are good picture takers; and when you master this camera, you can use any camera made. The Helios lens is good for "people pictures" because of its 58mm focal length; and it can be very, very sharp.

    To add to the confusion, GOST was re-calibrated to be identical to ISO/ASA in 1987 (date per Wikipedia). According to KMZ production numbers, the last Zenit TTL was made in 1985, so you can be pretty sure that your camera's GOST scale is the old-style scale, with numbers slightly lower than ISO/ASA equivalents. You can tell the production year of your camera by checking its serial number -- the first two digits are the last two digits of the year of manufacture.

    FWIW, what you (Nick) reproduced as "roct" is the Cyrillic equivalent of GOST -- the Cyrillic "G" looks like an upside-down uppercase "L" or a lowercase "r", and the Cyrillic equivalent of "S" looks like "C" ("O" and "T" are similar in both alphabets, at least in print, rather than script, fonts).
