Re: just got 7d, I am really frustrated right now.

What a load of bunk! 5 seconds of research will tell you that you can get fantastic photographs with those lenses and the 7D.



Everyone who has a problem with a 3rd party lens immediately assumes that they are all garbage. You could read the 10000 posts (maybe a little exaggerated) here about 7D focus issues and you will find that some people have had bad cameras, some have had bad lenses and most have had bad technique. I've personally had great experiences with Sigma and Canon lenses both. I've had 2 lenses total that have given me headaches, one Sigma and one Canon. Both issues resolved by sending the stuff in.

I'd love a world where everything would just work the first time out, but we don't live in that world. Frankly I'm happy when ANYTHING works first go round anymore, not limited to cameras and lenses.

Sorry I missed your "used center point" in your first post, btw. Phase detection is less accurate than contrast, but it's also hugely faster. I would do your tripod tests with a series of images and see what your "hit rate" is, how many come out in sharp focus. If your camera/lens combo consistently miss you can MFA, if they are all over the place, sending it in is a good idea. This is assuming a lot of variables that would be answered by even 1 example photo with exif.
