Re: Some crops with Olympus resized to 36 MP

I hope you don't mind me using heavy crops of your photos, I deleted them off computer when done. My example is much better shown than said...

Here is why I like larger sensor. It only looks bad at the pixel level (besides the top edge, I think your lens is faulty) because the A7R has so many more pixels. If you resize the Olympus to be fair. Simply import into Lightroom and export Olympus and Sony at Long Edge of 7360 (this makes the olympus slightly more than 36 MP since it is 4x3 ratio, but have to pick to convert to 4x6 or 3x4 crop.

The A7R is on the left in all these... Tell me, which do you think is resolving more detail?

Look at board grain in background

Upper right isn't too bad on your 24-70

Look at grass detail

Well there we go.

The A7R with a good lens and all its compromises still manages to provide overall better resolution than the EM1 with an excellent lens.

Is there a massive gap? No, certainly not. But there is a gap - and if resolution is important then the A7R & 24-70 is a slightly better choice, even at the corners.

And in the middle at the right focal lengths (which is where most people will be looking most of the time) - well no contest: the Sony runs off with the trophy.
