James;
I owned that combo for years and got many fine shots with it. It's a
great combo re bang-for-the-buck. But I recently sold my 300/4.5 because
I came on to a better solution for what I was doing - Zuiko 350/2.8
Could not afford to keep both. The 1 1/3 stop brightness is quite
significant for some things. Course the big weight difference can be a
huge negative for other applications.
Gary;
Wow! That's quite a task list you got there. I count 6 rolls of film to
do the listed tests. A great service to the list. THANKS! I'm assuming
your mention of the 350/2.8 tests to come are the tests I volonteered
for. I've got the film, all I need is a test target.
