This is quite interesting, especially the experience with a "bad"
sample. My concern is with testing a single example of a particular lens.
You may have tested a specific example of the 250mm f2, however it might
have been an exceptionally good example out of a bunch of fairly ordinary
performers.
I guess my question is:
How much variation can we expect between different examples of the
same lens ?
