Mate of mine, knowing my fondness for Samsung dSLRs, asked me if I’d ever tested them (particularly the latest, the GX20) for noise at high ISOs.
More to the point, asks me if I’d mind testing for noise at high ISOs… and maybe share copies of the RAW files to be inspected at mate’s leisure (could it be that mate’s contemplating purchase of one of these marvellous cameras? Whoopee!)
Coincidence is a wonderful thing.
For, coincidentally, I’d been itching to see how the new laptop (see previous post) would perform in handling batches of the whopping great 23/24Mb RAW files that the GX20 churns out, and was looking for an excuse to drag it out of storage and have another little session with it.
So I ask myself “Well, what’re mates for?”… hoik the camera out, get it fired up and ready, and go for a little walkabout in the immediate environs.
Mate was particularly interested in performance at ISO 1600, so ended up with a batch of 124 shots… 62 shot at 1600, the other 62 (identical scenes, so 62 scenes each represented by a “pair” of pics) shot at 800 for comparison.
Filched the lens from the GX10 for the test (cos I think the GX20 kit lens has “issues”), which is a Schneider-Kreuznach D-Xenon f/3.5-5.6 18-55mm. Not brilliant, but its all I’ve got at the mo’ (apart from the 50-200 that is).
Anyway, job done, thought I’d upload a few samples from the session to Flickr, just in case anyone’s interested (all the ones I uploaded are in this set).
And just to clarify, whilst mate had copies of the original RAW files straight off-camera, the Flickr uploads have been “tweaked” slightly (exposure adjustment, bit of sharpening, tad of noise reduction) and of course optimised and converted to JPEGs.
Also, for anyone who’s interested, the 4Gb RAM laptop breezed through importing the entire batch into Lightroom without even stopping to catch breath. Brilliant. P’raps now I can start playing with the GX20 again. Even more brilliant!
