Couple of days ago I was asked to do M-E and M8 comparison test shots at ISO 640 and 1250. Here is the link to the folder with original, not processed files. DNG and JPEG1. Lens was Summarit-M 35 2.5 and aperture was 5.6. M-E files starts with 100 in the file name, M8 with 101.
And just for myself I took ISO2500 shot with M8. Yes, it doesn’t look very clean on computer monitor, but I printed it on 4×6 gloss photo paper. And it came out as nice looking picture, without digital noise visible.
