Hey Guys, posted some pics a few days ago for you to test sharpness for me.
Didn't use great settings, so here is a new one.

Please tell me your thoughts on if my lens is as sharp is it should be.

f5.0
1/125
ISO: 100

On tripod
Straight off the camera

Thanks :)
 
OK Gary, I'll play :)

I am thinking you are unhappy with the sharpness or else you would not have posted. I have to say, I don't have the lens, but I suspect things are not as they should be. I would be inclined to blame focus myself though, even though it is overexposed. I had to have my 5d and two lenses calibrated to achieve the sharpness I was hoping for.

Hope I'm wrong and a user can correct my expectations.

Is this RAW or jpg? As jpg has some in-camera sharpening done already and RAW hasnt.

Answer me a question, when you say you had to have your lens calibrated, what part calibrated ? Do you mean the autofocus is slightly off ? When the lens elements are stacked in the body there is no adjustment, all the elements are fixed.

I have a 5d and a 135L and 24-70L. Previously on a 20d and 30d they seemed fine. However I was not happy with the focus on the 5d. I sent them all to Canon and they recalibrated the lot and it's all much better.

No, you miss my point Do they alter and peak the electronics or do they play around with the glass.
