My 28 seems to be okay, but you get chromatic aberration near the edges. Depends what you take as to how noticeable it is.
Sharpness is not too bad either.
I've had mine since the early eighties and it's still fun.

I have one and I like it, but my experience with 28's is a bit short...
Compared with my Nikkor-H 2.8cm it has better extreme corners performance on film and is smaller, faster and it has MFD of 25cm. However it flames a bit and has some geometric distortion.
But as you said, probably the adapter worth almost that much. |

Ever practical, I see the Russian Navy mounted an available T-34 turret on that patrol boat. I've never seen that before.

Well if you can't afford the lenses from well known camera makers, i.e. Konica, Canon. Nikon, Olympus etc....many (not all) of the independent lenses are a good 2nd. And IMO the best way to test\compare old lenses is on a film camera using the same film 
My Tamron 28mm f2.8 (which is practically the same as the f2.5 but was the version before) is ok but the Canon FDn 28mm gave better results as I noticed this once when shooting the same scene (not at the same time but same light conditions), the Canon was a bit sharper and gave more pop.
Anyway Nukemall copy looks very good..... congrats.

I have owned and used the Tamron 28 f/2.8 in the past, but the images were nowhere near as good as the samples shown above from the 2.5 version. They were in fact very disappointing.
I found the 2.8 version to be soft around the edges at nearly every aperture, and it lacked contrast.
The f/2.5 is a quantum leap ahead of it as far as I can see.
It receives mixed reviews here:

Try it, and see how it performs for you.
There is often variation in quality among old lenses, and you may have acquired a good one. Don't let other folks experiences influence your own judgement.
It would be of interest to all who read these forums to see how it performs for you, so a posting would be valued and appreciated.

In reply to your question, full frame on a Contax and cropped on a D200.
It worked well on the Contax, probably just me trying to get used to it on the D200. |

After your comments I dug out some test shots with my Tamron 28mm f2.8 and would say it's a good lens and if the f2.5 version is a quantum leap ahead..... the results must be amazing;-

I finally got a chance to test mine. Glows a bit and low resolution at F/2.5. Performance become very adequate at F/4 and pretty decent by F/5.6. A fairly small lens and color seem to be very saturated. Focus fairly close and I had a bit trouble getting the focus right on. Nothing special but not a bad walk around lens for crop sensor.
