Focus Problem on the t3i

[Kolourl3lind]

My t3i is having focusing problems. What can be the cause?  Can I fine to the focus like on the fullframe cameras?

Awwwhhh man!!!!! you mean you got to factor in the crop size for the reciprical rule? You got to be kidding me!!  It just doesn't pay to shoot with a crop sensor.

Yes, my friend, you do.  Everything is influenced by the crop factor not simply the focal length.

BTW, a FF camera will perform a little better in low light situations.

So, you have a 600 flash and a T3i?  Put that bad boy in E-TTL and let it do it all.  You may be surprised how well the photos are.  And yes don't move the zoom after you are finished with focus.

Sorry Sir I tried that. I realized my eye is shaper than some computer any day.
