Canon 17-40 f/4 USM L For APS-C DSLRs

1 posts
  1. Hi folks,

    I'm looking for a big animal lens to expand my capabilities. I've read the full frame conversations recently but I'm wondering how this lens and it's 16-35mm cousin work on cropped sensor cameras. I've studied up on the lenses on the Photozone site but underwater is always a little different. There is probably a good past discussion here but I couldn't find it.

     

    For you folks that have used it, is there a sweet spot you'd recommend? Do you use a diopter with these lenses? Or is there a nother lens I should be considering.

     

    I appreciate any thoughts.

     

    Steve
