Hmm, I've not noticed this problem even when I was messing about at ISO 12600.
By no means is it a perfect image but at that high ISO for snapshots I was happy. Unless of course Lightroom auto-corrects for it and I just never noticed.
RedFox88: This is essentially a 24mm f/3.2 lens in terms of FOV and depth of field. Goes to show you can have really fast & shallow DOF glass on 4/3 like a 24mm f/1.4 camera for 35mm SLRs.
In terms of exposure, crop factor does not affect aperture but it's effective DOF is simply because the image is cropped.
Ohh, might finally be able to replace my 14mm 2.5.
To those wanting the viewfinder and tilting screen, my feeling is they release this camera at this price point so they have a reason to release a true "GF Pro" at 1000+ bucks. If they release the "GF Pro" first, then they might have to price it lower or they don't sell any GX-1 cameras if they released it after release the true pro camera. What stinks is, yeah I want viewfinder/tilting screen and all that but I want to be paying this $699 not $1000+ price point where I'd rather spend the money on a lens for my Canon. Now they are set up to release the camera that everyone seems to want at a higher price point. It's a smart move by Panasonic in terms of a sales standpoint.
