Legendary soviet zoom lens with a zoom rocker, like it a lot, just not using it enough. Great for film work or for crop modes on sensors. Notably, this lens is not parfocal, at least in my experience - this was a kit lens on the old Krasnogorsk 2 & 3 16mm cameras, which were entry level soviet 16mm film cameras. However, the zoom lever is very, very fun to use. Good but used condition, tested on crop modes and OG BMPCC. Soft at 1.9 as youd expect, sharper stopped down. Please note- this is a REGULAR 16mm zoom lens, not a super 16- DCI 4K might vingette in some s16 crop formats. In the wonderfully universal M42 mount, Comes with micro 43rds adapter Can send pics on request. Downtown brooklyn or lower manhattan. Thanks!
