Sounds reasonable to me...! ;-) But beware the lens testing bug (it
starts so innocently, like by comparing two similar lenses...;-) -
it bit me, and I can't get rid of it! ;-) The trouble is, results
of testing are often inconclusive, but usually contain just enough new
information (or raise a new question) to cause the "just one more
test, and I should know" sequence syndrome...;-)
