I have a Canon EOS 10D that accepts Canon's EF
lenses. I presently own a 24mm to 85mm f/3.5 zoom which is handy but does not
deliver tight star images free of colour error/other distortions unless
stopped down to f/5.6 (!!!!!). I recently purchased a Canon 200 USM fixed focal
length telephoto which is very sharp, especially when stopped down to f/4. It
provides a great field of view for properly framing many nebulae.
It seems that all manufacturers have 'duds' in
their product lineup, and excellent lenses too. I have consulted some sites (www.photodo.com etc...) but
I need to hear from anyone has tried the Canon
100mm f/2.8 Macro for astrophotography, or the Tamron 90mm f/2.8
macro.
Also..
Which wide angle lenses deliver sharp stars free of
signifcant field curvature, distortion, colour error and the like.
Any duds to avoid?
Finally..
Any other lenses you could recommend for
nature/astrophotography?
Thanks!
