I am saddened to say, I had to send my Canon 7D in to Canon for repairs. Now, if you have been following the news about this camera you may have heard of excessive noise issues and auto-focusing issues throughout the internet. Fortunately this is something that does not seem to be happening (or have happened) to all Canon 7D's. However, a few out there do seem to be plagued by very unfocused images in conditions that should otherwise have had nice focus. Now, do NOT confuse this for unsharp images. Due to the Canon 7D's high pixel count, images will require a higher level of sharpening to achieve what other (less megapixel) models may have required. Don't let that fool you into thinking it's not a quality image though. However, if you focus and snap a few shots, and in post... even at sharpness setting 100 (or 135 even) you still have a soft image, then you most likely missed the focus somehow.
I have been shooting snaps off all month, and I can count on one hand the number of sharp images I achieved. I checked, achieving the same results on 3 different lenses. So it finally had to go back, fingers crossed that it returns with an amazing focus ability and low noise production (as some have reported post repair submitting).
Below I'll post a few of the images. These pictures have had NO sharpening applied (I tried, it didn't change much, for those not in focus to begin with).
Note that the shutter speed is 1/800, with an f/5.6 in most if not all these images. Keep in mind that at these speeds camera shake should be completely eliminated (I'm shooting at 4x with focal length) and I am not at a shallow depth of field either. For those who may state that lenses have a sweet spot at f/8 and I should have shot at f/8 clearly... keep in mind the resolving power of the Canon 7D places most lenses into a new sweetspot to avoid reaching the difraction point.

Now, let's look at the other 19 images (for the sake of speed, I'll only post 1, I can assure you they all look the same, despite changes in angle, distance, and zoom length).

This was a series of 20 shots. One of them, was sharp... 19 were just as this one. These were shot using Center Point (not spot point or AF Zone) without any "modifiers" on the lens (Such as an UV filter). I'd like to take this opportunity to remind you that I was shooting at 4x to 7x the focal length in shutterspeed, making camera shake a very unlikely phenomenon (1/800th of a second), and especially unlikely 19 out of 20 times.
