    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.

    I've noticed most of my fav pics on the forum have come from this lens. I want something wider than my PL25, so was considering adding another wide prime lens, but I may just sell the PL25 and get the 12-35. It really seems like its a great lens now and will be for some time to come. Thanks for posting these. Looking forward to some more!

    John... wonderful result, crisp clarity. I love the 12-35 and so glad it starts at 12, instead of at the common (and less interesting to me) 14mm.

    What ISO?

    Wow, I have to grab the horizontal scroll bar and scroll WAAAAYYY over to hit "Quote" and answer, lol.

    Don, I meant to post that. Those are ISO 640.

    It's not bad for the horrid lighting here in the mill -- I make a specialty out of pulling something out of available light here. As horrid as it can be, it can also be interesting, lol.

    I'll be interested to see what I can get out of the RAW from the GX1 though -- it just doesn't have the "depth" of the E-M5 or even the G5.

    Oh, and besides forgetting to mention the ISO, this was taken in the "Natural" photo mode, with -2 noise reduction and +1 sharpness. Contrast and what-not was left in the default. I prefer the "Natural" setting because it squeezes more into the low contrast jpg that results -- when I use the jpg that is.

    John.. I'll bet you can recover a lot of nice deep shadow detail with the RAW version. JPG just throws away so much information. :-/

    Okay, RAW version posted in the original post and it's way improved but a few things to consider:

    • I've been up all night and I'm tired, lol.
    • I did NO luminance noise reduction, so you can evaluate noise performance with your own standards.
    • I brought the shadows up substantially.
    Really, for a not top-of-the-line sensor design it's not bad at all for that light, handheld at 1/8th of a second.

    I can shoot the GX1 even though the G5 is better. It is usable especially in good light (which this is not, lol).
