I have a quick question about the comparison of ISO between FF and FT. I understood the math given in the presentation. Are the comparisons in RAW with no noise reduction/filter processing? I think it is but want to be sure. If correct, any comments latest mFT capabilities to handle noise in camera or LR5 ability to PP for noise?

If you are referring to Tony's video on crop factor ISO, I think it was just straight out of the camera RAW images between FF and MFT. I do agree with his video and the explanation is superb! We also need to take into account the camera's processing technology(which Tony also explained) because it could help with reducing the noise in camera (both RAW and JPEG) before PP noise reduction in Lightroom.

 

As for the case with my camera, Panasonic GX7, it handles noise very well up to about ISO 1600 and it is almost comparable to Canon EOS 650D or T4i or EOS M from my observation. But on lower ISO (200), there is still a little hint of noise, where in Canon EOS 650D the noise is fewer than in GX7. It's not a big deal for me though, I don't mind a little noise as long as it is not too much.
