How about taking some test photos that don't involve a moving subject, or you trying to follow a moving subject.

There is a tonne of info about this sort of thing out there so be sure to check.

Having said that, there are a few things to do first...

the 18MP APS-C sensor picks up a tremendous amount of detail. Because of this it requires extremely high quality lenses and extremely good technique on the photographer's part. I suspect that your kit lens just isn't up to the task. If you have a higher quality lens (macro, 50mm prime etc) put it on the camera, stop down to f 8.0 set up on a sturdy tripod, get good light, use a cable release or timer and take a few pictures. This is your starting point. Each of those items you want to change (not using a tripod etc) will mean that your technique will need to be up to scratch.

Also, birds in flight are very hard subjects at the best of time with the best of equipment. You need to try something a bit more basic before you judge anything.

Good luck. There is a reason this camera is not marketed to beginners. It really does require some solid skills.

Looks like blur and/or out of focus. Use a higher ISO to get faster shutter speed.

I'm no expert but just by looking at your pic I'd say it's a matter of shutter speed. Shoot AV if you're shooting landscapes or portrait. If you are shooting fast moving objects like the goose in flight, shoot TV or shutter priority mode. That photo does not accurately represent the capabilities of the 7D. Maybe a bit of a learning curve from the 550D?

Looks good but any picture resized for the internet is going to look sharp. Post a link to a full-sized copy.

I highly doubt ISO 100 will get you the shutter speeds required to freeze that bird in flight... Make sure they are at least 1/640 to freeze motion. That picture looks like the light is not that good, and probably would require ISO 400-1600 depending.

Its an ugly backdrop but it demonstrates that shooting on a 7D with an far slower lens the 28-135mm in poor lighting. Basically higher ISO, faster shutter speed and and not a single point mode.

Sometimes clothing just gets in the way. Good shot.
