I’m looking at buying a used 200mm
f2.8 lens for my 35mm camera and want some
advice.
Has anyone used this length lens
for astrophotography? If so how did it perform?
Michael Covington’s book gives the
field of view for 200mm as 6.87 x 10.3 degrees.
If you have a link to see an
example of the actual field of view I would appreciate that very
much.
Thanks,
Scott
