Vivitar 28mm wide angle lenses were made primarily by Kino Optical (Kiron), Tokina and Komine. There is a plethora of different versions see link below. The Kiron versions have serials 22xxxxx, the Komines 28xxxxx serial numbers, the tokinas 37xxxx serial numbers. This review page is specifically for the swappable T4 or TX mount Tokina made versions. Robin Parmars' list (link below) is a little unclear: his T93 is the earliest one, T4 mount, pics 1, 2. This was succeeded by the 58mm filter T91, TX mount, which was itself followed by the 52mm filter, more compact T92. His T94 is actually a t-mount lens that looks similar to the T93.
I have also seen a fixed mount 52mm filter 37xxxx serial f2.8 28mm that looks basically the same as the
tokina RMC (or SL) 28mm, this is not even in Parmars list.
Komine versions
here.
F2 "close focus" komine listed
here.
F2.8 "close focus" komine version listed
here.
Kiron versions, later versions by Tokina (37xxxxx) and Cosina (9xxxxxx) need/have a separate listing.
58mm filter
Swappable T4/TX-mount, PK-M (TX) and M42 (T4/TX) mounts available. Note that the TX PKM mount will fit on the early T4 mount lens but won't stop down without a diy modification.
