That reminds me--as a GH1 owner, an important discovery on this forum was that the GH1 RAWs have some NR cooked in to the RAW images by default. Paradoxically, setting the GH1's on camera NR setting to +1 or +2 eliminated NR in the RAW.

That's backwards. Setting NR to -2 eliminates NR, not +2 (or +1).

I've stopped thinking in terms of "equivalent" focal lengths on m43. 25mm is what it is, and what it might be similar to on some other format doesn't matter to me any more. We need to learn what to expect from our current equipment, not keep mapping it to the old. No one refers to their 50mm FF lens as "equivalent to 80mm on MF."

You'd think it's backwards, but it's been documented by our fellow forum members. Setting the NR to +1 or +2 results in no NR being applied to GH1 RAW files, while setting NR to -2, -1, or even 0 adds NR to RAW files at higher ISOs.
