"A previous post - http://soundimageplus.blogspot.co.uk/2013/12/sony-a7r-and-fuji-x-e2-jpgs-compared.html which compared a jpg. from the Sony A7r with one from my X-E2 created a lot of attention and an incredible number of hits and in fact has become one of my most viewed posts ever. In the light of the fact that a lot of photographers are interested in this, I've decided to do a much more comprehensive comparison including all the ISO values from 100-25600.
I've also decided to use a Fuji X 'native' lens, the 18mm f/2 stopped down to f/5.6 which many reviewers regard as it's sweet spot. I'm using this because the 18mm is a lens that is much more likely to be used by Fuji X shooters and gives a result that is more meaningful to them than me using an adapted Nikon lens which is not going to be that common. And while the 18mm lens may have some issues here and there, it's certainly very sharp indeed in the centre of the frame, so that will provide a useful comparison. I used my Nikon 28mm f/1.8 on the A7r.
Since I'm writing this before doing the test I'm assuming that the Sony A7r will have the edge at lower ISO's but the Fuji X-E2 may well show an advantage at the higher settings. But I'm going to present the image comparisons with no follow-up comments and let people use the blowups to come to their own conclusions."
