Help! Focus Issue Canon EOS 600D

Hi,

I desperately need help with my camera and it's focusing issue.

I have never been very impressed with the focus on my camera. I've never managed to quite get those sharp images I expect from an SLR. Oddly I seem to get better sharpness at first glance with my camera phone! At first I assumed it was because I was using the 18-55mm kit lens or my skills. I upgraded and purchased a Sigma 10-20mm, Canon 50mm and Canon 18-200 after all these I am still unhappy. I can't seem to get really sharp photographs and the issue seems worse on the wide angle. I assumed it was my photography skills so have been trying to eliminate all those problems like shooting in 1 shot mode, correct aperture, camera shake, ISO but still seems to exist.

I also wondered if it was a particular issue with the polariser so I tested it. I took a batch of photos at each aperture, tripod on and with the polariser, uv filter and none, and all of them just don't seem to be sharp. Set to ISO 100 and the AF point is centre bottom single point. If I look at the AF point in DPP it's just not in focus. These were taken on a tripod with self timer so the camera couldn't shake. Taken in raw converted to jpeg no other processing. See what you think:

I have just come across this thread here too and it seems like I have a very similar problem - i.e. the focus becomes more of an issue the wider the angle. The camera is around 5 years old and never had any other issues with it.

Could it be an issue with my camera? Does that happen? I am not that technical with cameras so not very good at testing it myself as suggested in this thread. Is it worth sending it off for repair?

Or do wide angle lenses need a particular level of skill to that perfect sharpness?

Or is is this the level of sharpness you get with these lenses and camera? The level of sharpness I am looking for I need to upgrade to achieve.

I would be very grateful for any help in sorting this!

Thanks,

Gemma

Try posting one example photograph on this site - straight out of the camera (full size and no post processing) - its not possible to get enough information to figure out your problem using flickr.

Pick one that you think should be in focus - maybe use the 50mm - no filters and use the tripod.
