I have an EOS 1D Mark II camera and I'm having some problems getting sharp, non-blurry photos--even at very high shutter speeds. I upgraded from an EOS 10D and I never had this problem with the 10D. I think (hope) that my problem is simply due to the fact that the 1D Mark II is so much heavier than my 10D was and I'm experiencing some camera shake. However, I'm a bit concerned that maybe it's an autofocusing issue and, considering the cost of this camera, I'd really hate for it to be that.
What would cause a photo to be blurred even at very high shutter speeds (1/1600)?? I took a photo of my son ,who was standing stationary, and it came out blurry. I checked the auto-focusing points (with EOS viewer) to see where the camera was focused and those areas that were blurry should have been sharp as the focus points were right on them.
I was using a Canon 24-70mm f/2.8 lens. The focal length was 70mm. I was using "One Shot AF" mode and ISO 200. This has happened to me quite a few times and I'm just trying to understand what the heck I could be doing wrong???? I'd taken a previous shot of my son (just a few seconds before the blurry shot) that came out fine (same settings, same AF points, etc). So why would one photo come out sharp and the next blurry?
Can camera shake come into play even at such high shutter speeds?
Thanks. I feel sort of stupid asking such an obvious question, but there are so many on this list with so many years of experience (which I don't have) that I figured it was worth feeling stupid if it will ease my concerns about something being wrong with the camera.
