The image doesn't look too great, it looks like too much Noise reduction or something, there's no detail in the hairs whatsoever.

Also the 70-200 f/4L IS has a known optical defect from about 160-200mm, wide open, at minimum focus distance. When you back up a little bit it is much better

You need a lot more light to do a proper test. My 70-200 f/4 is soft 160mm+ wide open. Go outside during the day and shoot some pictures out there. Try and get pictures at or above 1/640 of a second at about 100mm and then look at the pictures again. My L is sharp but keep in mind that 50mm 1.8 Is a freaking sharp lens and most primes will be sharper than a zoom.

there's nothing wrong with your lens; get out and shoot with it :D

I found mine "not as sharp as I think" too...

Maybe because lately I use my 100 L too much :)

Will do some sharpness test soon :)

When I first got mine I thought it was soft as ****e, much worse than my 50 f/1.8II. It's due to:
1. calibration issues
2. MFD issues from 160mm-200mm

Your one looks ok, but your image processing is causing a lot of smearing and detail loss due to noise reduction, either in camera set, or set in PP

Here's one without noise reduction, at 200mm wide open at f/4:

okay, i did as you guys suggested, and took some shots at a nearby zoo this morning. I'm less worried now. I have ten days to exchange it if it is soft that's why i'm going nuts with the tests. This one turned out pretty good. There were some soft ones in the bunch though.

Anyway no sharpening applied, shot at 200mm f4.
