......Focus issue... Canon DSLR Rebel

Archived from groups: rec.photo.digital.slr-systems (More info?)

Is it possible for a/this camera to show one thing in the view finder
(focus) and save something different to the card?

I use several lens, but my 85mm prime, which can be very sharp gives me fits
to. I shoot manual focus, I have played with the diopter, and I am aware
that shooting at f1.8 (or close there to) can be very very sharp and narrow
on focus range. But still, I compose and focus and things just don't record
to disc as I shot them, or so it seems. Oh, I wear glasses, if that matters,
my prescription is good.

I get home and I just can't believe half, not all, of my pictures are out of
focus. It is getting to the point where I want to take 3 shots of
everything, like "focus-bracketing".

With the Rebel, the only reliable focusing option, is the centred
single point option.

It shouldn't matter. If it is focused and sharp in the viewfinder, then
it should be focused and shart in the resulting image. I suspect that
the OP is moving the camera a little during the shutter snap. I
suggest taking high speed pictures to test this out and then work on
his/her technique.

Thomas and Stan

I will try the ruler test mention by Doug earlier.

Maybe the camera is a POS?

Wouldn't ALL the pictures be out of focus then? The OP suggested that
just some (about 1/2) of them are out of focus. This is the main reason
I suspect camera movement as the cause of the apparent focus issue.

I don't know if this is relevant or not to the OP, but I tried the test
Peter recommended from http://www.photo.net/learn/focustest/ using my
20D, and I've verified that it's screwing up the focus when using the
center focus point. It appears to be focussing perhaps 1cm short :-( I
had the camera on a tripod, so I'm certain camera movement wasn't the
problem. I found that the other focus points seem to be right. This
could perhaps explain the "50% of photos out of focus" issue. Maybe 50%
of the time it's not using the center focus point.

Does anyone know if this is something that could be recalibrated?
