Should this photograph be more clear as you zoom in?

Pulled into work and a nice young deer was watching me. I had my Canon 5D4 on my seat with my Canon EF 70-200 f/2.8 L IS USM II mounted and ready. I sat my camera on a few towels on my roof so the camera was good and steady. The lens IS was turned on.

The camera was on P and the lens was zoomed to 200mm and the camera choose F/2.8 1/200 iso 1250 because it was still pretty early. I pretty much focused between his eyes as I was wanting the head in focus and he didn’t appear to move when I took a few shots. This is the best of the few.

I was 67.5 feet from the lens to his head.

This was shot RAW and since I’m posting here for ideals I did not touch it in any way other than import to LR then save to my IPad photo roll using max setting settings.

I’m just wondering if you think it should be more clear as you zoom in some or is it about as good as it gets considering it was over 67 ft to the deer’s head?

It looks to me as if the sharpest area is a couple feet in front of the deer. Wide open will be a pretty shallow DOF. Could be the lens is needing some calibration.

Low contrast makes things look less sharp plus you may have some noise issues there at the high ISO. I think that low contrast is the biggest issue.

Yes it certainly could be sharper. Focus on the eyes is best but it’s a nice enough picture.

I do agree on focus on the eye but I did focus directly between the eyes, about center of his forehead and that’s not even as clear as I would of expected for a non hand held shot.

Is that normal for this particular lens to need adjusting?

The leaves front and right are in focus. Do you have a review screen that shows your focus points?

It seems that my focus point had got shifted from the center one that I always use to one on the lower left side of the camera but I still had it focused on his head. I shot this using BBF and only one focus point.

I know that when working on a tripod you should turn IS off because it causes some odd focus issues when there are no movements to counteract. I'm wondering if this could have contributed to your issue.

I’m now wondering the same thing. I’m going to sit this thing up on a tripod and find a focus chart and play with it some.

One thing I can’t find out is what is an effective distance using this lens at 200mm. Was 67ft pushing that distance? I know there has to be some numbers somewhere.

I wouldn't think so. Ejones may have answered your question. with your camera nested in towels you may as well have been shooting on a tripod. That is a big red flag. Goofy things happen with IS engaged.

You asked "Was 67ft pushing that distance?". There’s no such thing as pushing a lens too far. Unless broken, it focuses the same within its zoom range.

It would seem that given the focus point you show it should have been spot on .., the long green weed in front of the front hoof is in focus and the leaves on the tree to the right or pretty much on focus ..

I sharpened up your photo a bit and while the deers face is now pretty clear for most ...when you zoom in .. the weed in front stays in focus while the deer gets blurry ...

Either the deer moved during the shot or the lens /camera needs a simple calibration ..

Sharpened a bit .

I'm going to try a few more shots with no IS and see what I can come up with. Just to many settings to thing about when wildlife is standing there staring at you lol.

Thanks everyone for the great advice.

Thanks! that looks great. considering I was dealing with a wild animal and trying to check settings he could of moved a bit as I hit the shutter or maybe I moved the camera slightly as it was on a car roof and I had my hand on it.
