I'm really sorry for posting a question that I'm sure has been asked before, but I had trouble finding what I was looking for in the faq and archives, and well, a search for "wide angle lens" turns up a haystack.
My dilemma is this:
I've been using a Tamron 19-35 and was quite happy with it for my limited needs until winter hit and now all of my family shoots are moving indoors and I've been using it a lot. The IQ just isn't there for it to be a main shooting lens, so I'm in search of a better WA zoom.
I use a mark II, so I need a Canon EF, Sigma DG, or whatever equivalent. I'd like to keep it under $500, and don't mind buying used, but wondered if anyone can recommend anything?? Is there any such lens?
If you're sick to death of these types of questions, please feel free to mosey on by this thread, but thanks so much for any help!
