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 f2.5 swappable TX mount Tokina made versions. Robin Parmars' list (link below) is a little unclear: his T93 is the earliest one, T4 mount, all metal ribbed focus ring. This was succeeded by ones with rubber focus rings: this lens, the f2.5 58mm filter T91, TX mount, and the 52mm filter, more compact, f2.8 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.

First T4 mount version, f2.8 (R. Parmars' T93) listed here.
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 TX-mount, PK-M (TX) and M42 (T4/TX) mounts available.

Lens Review Date: May 10, 2017 I can recommend this lens: Yes | Price: $33.00 | Rating: 9 

Pros: IQ, Contrast, Build
Cons: MF, Weight (Build)
Sharpness: 9    Aberrations: 9    Bokeh: 9    Handling: 8    Value: 10    Camera Used: K-S1   

Good performer in its class of manual focus wide angle lenses. It is quite sharp on an APS-C body. Your mileage may vary on a full frame, however: I've see reviews that question its quality at the corners. It has good contrast and unlike many lenses from this era it keeps chromatic aberration in check. I own SMC K-Manual 50mm f1.4 and DA 50mm f1.8 and I would put the image quality of this lens on par with those.

It is beefy. It will make the camera heavy compared to today's economy plastic lenses. The aperture ring is a bit narrow and hard to feel for. It is easy to feel the TX mount grab ring and think it is the aperture ring.

I don't think the Vivitar 2.8s should be lumped in with the 2.5s, I think the 2.5s were given extra design consideration. I also don't think we can compare 2.5s from different source manufacturers to each other. That leaves a dizzying matrix of Vivitar lenses that need separate reviews but it's the only fair way to do it.

f16 sorry about the sensor dust
