Took a quick picture the other day and decided to go through my normal PP routine. For some reason, I feel I see a lack of clarity from this camera and lens (Canon 5D Markii, 50MM 1.2L) This image was shot at F11, 1/200, 100 ISO. Do any of you agree? Am I missing something?

When the only sample you provide us is a shot with so many different planes that its impossible to tell what you were focused on its hard to have any definitive opinion. Especially after you have resized it for the web. To determine sharpness take a photo of a subject with some detail, but that fills enough of the frame that the majority of the picture isnt background/foreground.

Of course it's possible the lens isn't calibrated or some other issue. However, the most likely cause of unsharp images is your skill behind the camera, or lack thereof. So it's probably a matter of getting more practice. Based on the provided image (small size, no EXIF, bad test subject) it's difficult to say anything certain. The flag seems plenty sharp. The pine needles can be blurred by camera shake, shallow depth of field, or wind. What was the shutter speed and f stop?

1/200th in a scene where literally everything is moving is not going to be the sharpest image. There's obviously enough wind there to make the flag move, so all of the pine needles are moving also... the only thing that might be sharp in the whole photo would be the flag pole, as it doesn't appear that the wind is strong enough for the flagpole to moving around too much.

I can't see anything wrong with this photo. Bright colours, focus on the flag - so what are you complaining about?

Interesting. Thanks for the input. This is all fairly new to me. All past recollection has disappeared, unfortunately.

I agree. My focus point was the flag itself. With the wind blowing, I wasn't too interested on the clarity of anything else, besides the flag. I'd have to double check, but I believe F stop was 8.0 with a shutter of 1/200.

The wind was very minimal, but enough to generate movement of the flag, obviously. With that said, on my PC, a lack of sharpness or clarity seemed very apparent and I was curious of others opinions on that matter.

Yes.

Good deal. Not complaining, but seeking opinion on the sharpness of this photo (flag). It seems it's there, but my PC is not up to par on this matter.

You need to post unaltered 100% crops if you really want to judge sharpness. Looking at it in this size I don't see how the flag could possibly be rendered any sharper.

There's what looks like motion blur on the trees. And something goofy going on with blue color, at least on my monitor. The flag looks sharp, though.

I had this lens and sold it. For the price and weight it just didn't perform well - lots of CA with bright scenes. For portraits in studio I think it would be nice; but to lug it around as a walkaround -- not for me. Still I agree that the flag looks pretty sharp to me and that's your focus I assume.
