You're assuming that these lenses are equivalent, but the Panasonic lens is actually a better lens.

He's right, RAW files typically have a (somewhat lower resolution) JPEG preview embedded. I believe (though I haven't checked) that the E-M5 also has this.

It looks like Snapseed supports RAW on the iPad, but it doesn't specify which RAW formats.

Thanks. Do you know if it does distortion correction, or is it just a plain dcraw-style conversion?

Does anyone know of a (good) RAW-development app for tablets (iPad or Android) that supports Olympus (E-M5) RAWs? I was thinking it would be nice to have some kind of tablet along for trips, but I...

Maybe not. I usually stop at f/4 or f/5.6, whichever is sharper for the particular lens.

To avoid/reduce chromatic aberrations.

I don't think it's controversial. I only mentioned it because I feel this is a point that is often overlooked when people complain about how expensive certain MFT lenses are. And I'm not saying...

Which lens is better, though? (I don't know anything about the Nikon-lens, but I'm pretty sure the Panasonic is quite a lot sharper than Canon's 50mm f/1.4.)
