I'm thinking I may be switching to a full frame body in the near future, and looking for advice in how to update my lenses.
My current lens setup is:
opteka fisheye (wouldn't work on a ff body)
Tamron 17-50 2.8 non vc (wouldn't work on a ff body)
helios 58mm adapted m42 mount (would it work?)
canon 70-200 f4
I would sell the tamron and the opteka, and need a lens to replace the focal range of the tamron, a new fisheye would come later down the road.
I'd like to stay around $600 ish:
24-70 is probably out of my price range
24-105 seems like a good option, similar effective focal length to my tamron on a crop body, although f4 is kind of slow, maybe this and a fast prime would be good
17-40 is another option, also f4, this would be wider than the tamron, which i'm not sure if that's a good thing or not
I shoot mainly sports, skiing is my main sport, but I dabble in other areas as well
I guess what I'm really looking for are suggestions about which lens would replace the tamron 17-50, I'm definitely open to non-canon glass, too.
