Photozone review of 100-400 L II
« on: December 19, 2014, 02:50:20 PM »
The review I have been waiting for:
http://www.photozone.de/canon_eos_ff/896-canon100400f4556is2

The measured MTFs are just so good. It is exceptional in the centre at 100-300mm, and still very high at 400mm. At 200mm, it nearly out resolves the 5DII sensor with a score of 3700 LW/PH out of a maximum of 3800, far better than the 70-200mm IS II. At 400mm, it resolves 3450 LW/PH. The sharpest aperture is f/5.6.

Comparing with the Mk I, it is way ahead for 100-300mm and significantly better in the centre at 400mm.

It's even better than the 400/5.6.

They are certainly glowing about it.  I love mine, but felt that the higher contrast tended to make the image appear sharper.  The greatly improved middle and outer edges also make the overall image look a lot sharper.  I believe there is less CA's, but it wasn't a issue on the MK I.
 
I've seen your tests, and they seem right to me, there is always lens variation, but they are as expected.
 
One interesting thing is that the lens center MTF is always highest wide open, and the edge MTF increases very little as you stop down, while the center MTF goes down a little.
 
It is still excellent at 400mm, where I would use it most, in fact, I have only used mine at 400mm, so maybe I should have went for the DO.
 
Roger at Lens Rentals tested 4 each with his new transmissive target.  He just looked at 400mm so far, but did not measure much difference between ver 1 and 2 in the center.  He does warn that he wants to test more lenses to get better data.
