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

Thank you for inputting some sanity into this thread, with a very competent post. One of the best comparison posts I have ever seen.

Remarkable how the A7R+24-70mm combo outclasses (!!) the Oly E-M1+12-40mm. I would like to see the A7 or maybe A6000 in this mix as well ...no contest whatsoever .

Thank you for thread starter to provide the picture material, even though his intention was to show how good m43 are in comparison
