General observation on wides: if you have and use a 50mm, a 28mm is a classic first wide.
I prefer a 35mm as a normal, so my wides are 24mm or 19/20/21mm.

A cheap but very good ultrawide is the Vivitar/Tokina 17mm (usually much better than the equivalent Tamron, but apparently with lots of sample variation, with the Vivitar branded ones doing better), but I'd only consider that after one of the focal lengths mentioned above.
The point I was trying to make about comparing lenses in general and particularly twenty five year old lenses is that we don't know how each example would compare with the other ones initially on test when they were manufactured , and after twenty five years of being kept and used in different manners in different parts of the World probably by several different owners my FD 24mm f2 optic might give very different results to another example of the same lens that somebody else has thousands of miles away in in a very different climate.
