Okay, came into work with the GX1 and the 12-35mm and took one shot out in the dimmer part of the teeming aisle of the mill while they were doing startup preparations. First picture is straight out-of-camera jpg, second is slight sharpening and curves adjust in GIMP which is all I have at work to deal with and I have a crappy monitor here at work so even I AM not sure what they actually look like. [EDIT: Third photo from RAW added -- so the sequence is SOOC, Edited SOOC jpg, and JPG from RAW.] It's at f/2.8, 1/8 second, 25mm (50mm equiv) focal length. I'll push it more later but this confirms that the stabilizer helps at least out to 2.5 stops. I'll add a third shot from RAW sometime tomorrow after I get up to see what it comes out like. I used the GX1 rather than the G5 deliberately to see what it can do -- I'm pretty familiar with what to expect from the G5. AND HERE'S THE RAW VERSION TWEAKED IN LIGHTROOM. I did NO luminance noise reduction so you can evaluate how the noise is for your own purposes. Again, original shot at ISO 640, lifted the shadows in LR 4.4 "100%" whatever that means, lol.
