I don't know if I'm obsessing too much here but i was doubting the sharpness of my 70-200 f2.8L II so i took some shots outside in day light without mlu and then with it. On a tripod with a remote

does this look right?

Shoot more, pixel peep less. Look fine for 100% crops.

Am I the one that's crazy? They all look the same. You are obsessing. No more test shots and shoot stuff you want!

It's a contagious disease caught from reading POTN posts.

If you can tell the difference between the above images... get a life and stop pixel peeping!

Doubting the 70-200 f/2.8 II? Seriously? If that lens doesn't deliver the goods, none does.

You've picked a man-made item for the sharpness test. Man-made things often have limited detail, especially signs or printed stuff. Shoot a forrest from 100 yards and you'll have lots of detail (trees, branches, twigs, leaves, vanes within the leaves).

If those are 100% crops, they look great to me. Remember, real images are NEVER viewed at 100%. Export a JPG image 1500 pixels wide and view it from 3' away to simulate the detail you'd see in a 4x6 print.

They look good to me.... except the f/8 without mlu. Looks like some motion-blur happening in that one. mlu images are the "telling" ones. Chill! ;)

Not to make light of your concern but I feel there is a joke in here some where using a warning sign to figure out if there is a problem with your fantastic glass.

f8 wo/ mlu is not as sharp as others - anyway, you do not have to vary the apertures for test shots on a flat surface - as n1as had said: you may want to test your lens by shoot a scene of 3d objects at a distance
