Thanks for your comment.
About the comparison with the EPM2, our review says : “the Olympus E-PM2 adopts a different sensor altogether and outperforms both the GM-1 and EOS M2, albeit only marginally.”
The EPM2 scores slightly higher than the EOS M2, difference of score is not higher than ½ stop. Please keep in mind that the EPM2 sensor is significantly smaller.
NEX 5T and EPM2 are not identical at all, which elements give you that feeling ?
