What's going on?

So...I don't know if this is something I've been doing wrong, but I've found recently that when I'm using my Canon 24-70mm L lens on my 5D3 that if I'm focusing on a subject that is say, 50 meters away, the image doesn't appear sharp, when zoomed in to 100% it looks sorta fuzzy. I'm not using any sort of filter on the lens, but just wondered is this sort of thing normal?

Does it look fuzzy in live view Ian, or do you mean on the computer once you've downloaded it?

If you mean that it looks fuzzy on the actual camera then have you knocked your diopter slightly? This may be enough to alter how everything looks.

It's actually on the computer itself, when downloaded.

At 50m it really should be in focus, even wide open, I'd set the camera up on a tripod & do some proper focus tests - otherwise there's no way to be sure as sharpness depends on so many variables.

What shutter speed/ISO are you using at what focal lengths?

ISO 400, shutter speed is aaround 1/250 and its normally at the 70mm end of the zoom

New lens or body?

It's not heat haze, is it?

I think this is the kind of thread that would really benefit from some images.
