Ah, the expert has spoken. Thanks for the correction, I'm just a happy user/collector 🙂
The Zenit SLRs address the issue of closeups and TTL viewing, to make this on topic
🙂
The Zenit 1 was the Zorki 1 with a mirror box. The mechanism is very primitive- it is as if an external mirror reflex attachment was fused into the camera. Complete with the levers and pins, which are what will be found if the top cover of the Zenit 1 was removed.
There are other similarities as well: no flash sync and separate rewind switch. The separate rewind switch was introduced with the Zorki-2.
The Zenit-S (C) was based on the Zorki-2C. The mirror reflex mechanism was modified, using a string and pulley method similar to that used by the Contax S and D SLRs. Aside from that, both have flash sync, a variable sync timing dial, a rotating shutter dial with a central marker which allowed speeds to be changed before or after cocking, and the rewind switch was incorporated into the shutter release button.
Likewise, the Zenit 3 was based on the Zorki-5 (bottom loading), and the Zenit -3M on the Zenit-6.
There were no Zenit based on the Zorki with slow speeds, ie, 3 and 4. It appears that the extra slow speeds complicated the mechanism. Both the slow speeds and flash sync timing mechanisms were built around the main shutter drum shaft. An SLR would add another function to this already crowded section: the Zenit 1, C, 3, 3M had their mirror viewing mechanisms built on the main shutter drum shaft too. This is perhaps the reason why the descendants of the 3M, the popular Zenit B, E, 11, and 12 series (including the 122, 212, 312, and 412) have no slow speeds.
No slow speeds. Now that's another drawback (for some).
