Camera body & sharpness

I was just wondering if there was a way to tell if a camera body has a sharpness issue. I remember reading articles about how sometimes people would notice all of their lenses needed similar micro-adjustments due to the camera being at fault. I own an XSi so it is impossible for me to determine via MA.

Thanks

If you don't notice I don't think it should matter but a trick you can do is get a ruler and place it against a wall at 45 degrees. Then mount your camera on a tripod level to the ground and autofocus on the 6" mark or something in the middle. Then pull the image on a computer and see if more ticks are visible behind or in front of the focus point. Typically a lens should back focus slightly more than front.

It is normally not a fault of the camera.. It is usually the combination of both camera and lens..

Lenses that are sharp on my 20D were so-so on my 50D until I did a little AF Micro adjustment..

It all to easy to blame the equipment than address technique or getting to know your equipment..

Could use my DIY setup too, it works on the same premise.

Yes it does happen. You need to test it with more than one lens at same settings to see if it's a body issue. I had soft photos when I first got my XTi and everybody kept telling me it was a user error. I did the focus chart test but it was fairly inconclusive. I only had one lens back then, it was old and beat up and I thought it was the lens problem. When I bought a brand new Nifty and saw the same problem, I sent the body to Canon, it came back with a letter stating they found and fixed a focusing issue. Focused perfectly ever since, until I sold it 2+ years later.
