Originally posted by illdefined thats definitely an extreme case, not one you'd encounter often. power drain has been a universal knock on the GRIII so far (even with its bigger battery) and I still question the ability to take handheld low-light shots when the other universal knock on the GRIII is its terrible low-light focusing
If photos turn out, one can shoot in as dark a condition as the camera will reasonably allow, e.g. those extreme cases become less extreme
(That's the dream)
In my experience focusing thus far, the GRIII is just a shade slower than the GR in lowlight (and I mean *very* lowlight - the condition I spoke of earlier was a reading of 1/8sec, ISO1600, f/2.8 on my incident meter). But that is to say that it (GRIII) seems to find focus accurately far more often while the GR either misses or can't lock. The GR's low-light focusing got much better over time with subsequent firmware updates; I'm hopeful the GRIII follows that pattern. But as it stands, though it's nowhere near as quick to focus in low-light as the old GRDIII and GRDIV (which do so almost instantaneous - impossibly fast in near darkness), it can do it fairly reliably and the end-result image is far better in terms of sharpness, dynamic range and noise than either of the other iterations. All this is to say, I've not had it long and these were just off-the-cuff, extremely anecdotally oriented, wandering around my house, "tests".
