Lens Options
 

I am looking at a few lens options and was curious if anyone had any experience with any of these.
-Tamron 24-70 VC
-Tamron 17-50 VC
-Sigma 17-50 OS
-Sigma 50-150 OS

So I would most likely either get just the 24-70 or get one of the 17-50s and the 50-150. The 24-70 is the only full frame lens of the bunch and it seems to be the nicest. Does anyone have any of these that would care to comment?

What camera will you be using? What is your intended use?

Not much to go on here...

It's going on a 7D. And I am planning on using it as all purpose lens. I'm trying to get a feel for if the Tamron 24-70 is so much better that I wont mind missing out on the additional range I would get if I got both the 17-50 and the 50-150. Also, the OS version of the 50-150 is pretty new and I haven't been able to find many reviews on it, so I am curious if anyone has any experience with this newer version.

After much research, I am running a Canon 17-55mm as a primary lens on my 60D. This is ideal for my use - I wanted a wide-angle zoom, as I'm frequently shooting interiors and trying to get the whole room.

If that sort of use appeals to you, you'll like the 17-50 or so range. 24mm is only a moderate wide-angle on your 7D. 17mm is a true wide-angle (full-frame equiv. is about 28mm)

I can't comment directly on the lenses you're considering, but I do like that 17-55 and the range is perfect for many wide-angle interiors!

That the Tamron 24-70 covers full-frame doesn't matter to me; I made the decision that if I do go to a full-frame camera in the future there will be new lenses, too. I wanted lenses for today! YMMV.
