Title: a7II vs A7r
Post by: jgcox on October 16, 2015, 04:33:06 pm: I'm looking at one of these (not the a7rII) I'm wondering if one of them is any better with wide angle lenses. I have some wide angles that I use on my Leica and I'd like to use them on this purchase.

So most wide angle lens are sort of on the margin to start with, even on a low MP sensor, I would go with the A7II. Probably will work out better.

The only meaningful difference will come from the image stabilization on A7II. Other than that they should be the same for the same output size, unless you start to go really big in which the lens imperfections will start to show. Nevertheless images from A7r will never look worse than A7. It is not like A7 will add sharpness to the smeared corners that A7r can't. They both will look bad (there will be a slight difference in edge acuity because of different ratios of scaling used).

I do think that A7r has better DR then A7II, so if you are doing wide angle landscapes, that may be something to consider.
