| p.1 #7 · Compare 5DIII 1.4X F8 Performance to 7D W 400mm? |
I did a semi-controlled test indoors with my 5D3, 7D and 400/5.6L and a 1.4x II for my fellow Icelandic photobuddies, so please excuse the Icelandic text, but here is a 1:1 crop of a 7D picture with enlarged-to-match files from the 5D3, with and without an extender. This test was primarily made to see differences in possible resolution - nothing else. Please don't look at brightness / colors as I fiddled a bit with them to make them look as similiar as possible, to not get in the way of the resolution comparison.
I made a link instead of an image reference as the image is too wide and I don't want to mess up the thread width:
My real-world experience tells me that the only thing the 7D is good at compared to 5D3, is reach and AF speed (against a 1.4x on the 5D3 - a bare lens on 5D3 is at least equal or better than the 7D regarding AF speed). Given that there's enough light to keep the 7D at ISO100, the 5D3 wins everything else, and if it's not too bright outside, the 5D3 will win the 7D - even resolution wise, as bumping 7D's ISO will loose all of it's resolution advantages against 5D3.
I'm a long time 5D3 user who just recently added a 7D primarily to extend my 400/5.6L lens, and I find it painful to work with the files from the 7D, compared to what I'm use to with 5D3's files. The 7D will be sold soon
