Testing a super-copy of the 100-400 L IS

Fatbirder's Top 1000 Birding Websites


I used to have the general impression that the 400 5.6L is sharper than the 100-400 L IS at 400 mm, wide open. My first copy of the zoom is not bad at the long end, but it sharpened up noticeably if stopped down to f/8. Having been spoiled by the sharpness of the Sigmonster, 500 f4 L IS and 400 5.6L, I relegated my 100-400L IS to back-up duty, and it rarely left my camera bag.

Recently, during routine testing of my and my friend's gear, I was amazed to see a super-copy of the zoom (my friend's) that's as sharp as the prime at 400 mm wide open. I couldn't believe my eyes, so I repeated the tests over and over again, using both MF and AF shots. The results were consistent - my friend's 100-400 L IS is performing like a prime.... probably among the best copies of the zoom ever manufactured by Canon. It's as sharp wide open as at f/8, and the only reason to stop down is for more DOF. I promptly sold my first 100-400 L IS, made an offer that my friend couldn't refuse.... and this super 100-400 is now residing in my camera bag....:)

I'm very impressed with the performance of my new 100-400, even with a 1.4x TC (560 mm, wide open). I guess I'm falling in love with this lens again. This gallery contains test shots from the super-zoom. Contrary to my initial belief (and common internet forum wisdom), the 100-400 L IS can be very sharp at 400 mm wide open if one is lucky to get a rare, excellent copy.
