So, I have an off-brand 28mm lens - how to evaluate character?

Speaking of Vivitar, I recall their 2.5 28mm (I believe in Canon FD, at least) garnered a good reputation amongst some shooters, so you might keep an eye out for one in your mount.
 

Also look at the lens contrast. Before Vivitar came out with the Series I lenses, I bought a Vivitar 70mm to 205mm zoom lens and its contrast was greatly inferior to all my other lenses which were Minolta Rokkor lenses. I have been very careful since then when buying off brand lenses, although I am pleased with the three Tamron lenses and 2X extender that I have now.

Hmm, OK, reading about lens contrast right now (ability to define boundaries, or "contrasty" contrast?).

Practical ways to evaluate contrast, for the commoner?

Look through the viewfinder, rangefinders need not apply. There was a big difference when compare, but normally they are not compared. Looking at a subject and changing lenses, I could see a big difference which always bothered me.
