I do shoot lots of MF though. It's just always wide angle.

decent photo slightly cropped same settings as all my bad out of focus shots no adjustments other than crop
Have you experimented with the settings in the AF/Drive menu (C.Fn)? When I had the 7D, I tried a lot of different settings there, and with some trial and error, I was able to get a great keeper rate with a 70-200 f/4 IS. If I recall correctly, the AF servo sensitivity can be adjusted, and you can set the priority for tracking or focus.

idk what to experiment with, but ill try anything after what happened today. i also dont want to shoot soccer with just a 70-200 anymore just isnt long enough. 70-200 with a 1.4X maybe

my biggest problem hands down is that a lot of shots that could have been good had the single center focus point directly on the player no question about it and still missed horribly either putting the background in focus or absolutely nothing in focus and sometimes it came out with girls far in the background in focus that were no where near my AF point in the VF. im just so confused and sad from all the shots i missed today. i kind of wish it was a canon zoom instead of sigma because i never had any trouble with anything canon before

Well, read the manual on the AF/Drive menu, it explains what the different settings do pretty well actually. I used a 7D + 70-200 f/4 to shoot greyhounds and BIF's and was surprised at how many keepers I had.

EDIT: Forgot to ask, and maybe a dumb question, but are you shooting in burst mode?

I've owned both and I can tell you that's BS. It's not hard to beat the 5DII's AF.

Looks to me like you were too fast or too slow with your tracking. They're not just slightly out of focus as if it were a lens issue, those are real good misses.
post #15078 of 29551
If I had to guess it would be the tracking sensitivity being too high. Even at the normal setting it'll try to swap subjects really fast if your AF point drifts off your target a bit.

EDIT: Also, first time at the track with the 7D today. The image quality might be the same as my T2i but its sooooo much easier to use. I've got like 350 shots to go through but this one already stands out, at least for me.

yes i was shooting burst. i dont know why i did, i stopped doing it a while ago but for some reason did it today. im guessing that was a bad choice right?

i was doing high speed burst and it actually was shooting really slow for some reason even when shooting jpeg

"macro" now dont even mean higher magnification, just closer focus.

im just really disappointed. i dont think i want to shoot field sports anymore unless its with my own glass which i dont own anything long enough to capture the action. i just cant figure out if my problem is my user error or sigma or the f2.8

either way unless they pay for me to rent a canon telephoto im not shooting soccer for them anymore because my sigma experience today was terrible because like i mentioned canon 70-200 @ 200 2.8 i didnt have trouble keeping focus much less missing it in servo :|
i dont even think you need 2.8, grab a canon 70-200/4IS and call it a day.

i remember when teh 7d just came out there were issues with AF switching too quickly. i dont think the sigma could keep up (was it a HSM 70-200?)
