Hi,
Just after some info on whats a good widefield prime for astro work.
Looking at primes between 15mm and 35mm and as I am on a budget, under $400-$500+. Canon, Sigma or other?
Any one recommend anything in this range? and any links or images taken with them. Was thinking of the EF 28mm f/2.8 but have heard that it`s not the best for astro work..
Thanks in advance
Gary
