I thought you might want to know that I’ve posted my review of the new Canon 200-400mm. It would be awesome if you could share that with your readers.
Canon EF 200-400mm f/4L IS USM Lens with Internal 1.4x Extender
From Ron Martin:
“At 8 pounds, this lens is like carrying a baby around – however it feels much heavier. I hear girly men whining all of the time about how the 3.28 pound 70-200mm is too heavy, so when you pair this beast with a 3.5 pound pro body like the 1D X, you are going to get tired arms quickly.”
“Overall I found myself really loving this lens during my testing and the ability to easily flip the extender from 1x to 1.4x was delightful. I’d pay a few extra hundred bucks to have this feature on my 70-200mm because l love it so much!”
“During my field testing I always had this lens attached to a Gitzo GM5541 monopod with no head when it was in use. It’s just too big and heavy to wield freehand, but I was able to get sharp shots below 1/ thanks to the brilliant image stabilization performance.”
Canon 70-200mm f/2.8L IS II vs 200-400mm f/4L
Despite being in identical conditions focusing on the same exact point, Evaluate Metering chose to create a longer exposure for the shorter lens resulting in an image that feels about one stop brighter. I see this most often with lenses that aren’t as bright, so this tells me that the optics in the 200-400 are very good and that they gather light much better, despite being a f/4 lens.
The other thing I see when I zoom in (which you can do by clicking both images to download the original) is that the 200mm-400mm is slightly sharper. I see this pattern repeated at f/5.6 as well, so I was happy to see that this is some pretty sharp glass (as one would expect at this price).
