Additional information:

Tamron 28 mm f/ 2.8 Adaptall model CW-28 is a wide-angle fast prime lens for 35 mm SLR cameras popular in the 1970-90s (via the interchangeable Adaptall/Adaptall-2 mount).

It is multicoated. The lens shows very good sharpness and contrast. There is a slight fall of resolution on the edges. It also came in silver design (see the last photo).

There is a rare version of the lens, produced in black and silver design. The key difference from the later variant is a different filter diameter (55 mm vs. 52 mm). The 2nd, 3rd and 4th photos present this very version of the Tamron 28 mm f/ 2.8 Adaptall lens.

The Tamron 28 mm f/ 2.8 Adaptall had specific advice for landscape and interior photography.

Period of use: 1 month

Strengths:

This lens is something really good wide open sharp from corner to corner even on APS-C sensor cameras, really rare this in manual focus wide lens.

Weaknesses:

Weakness is the 5 aperture blades but who needs it? if wide open is sharp already. Like all wide lens has some distortions. Rare to find

Comments:

The second version of this lens with 2.5 aperture and 49mm filter is a little bit better than this but not much big difference. Abut how great is this lens I post one test photo made with wide open from my computer screen.
