This cheap MMZ camera is very hard to find nowadays. Despite it's rarity at least two versions of Smena-2M camera existing:

Type 1. Camera identical to the Smena-M under name in Cyrillic „Смена-2М“. Comes without selftimer, but with synchronized flash.

Type 2. Camera identical to the Smena-2M (type 1), but under name in Cyrillic „Смена-2“. Camera synchronized and with delay mechanism.

Also two different types of „Смена-2М“ text: see the letter M after 2 having short or long beginning, both with selftimer.
