After doing a reset on firmware 1.02 the glitches didn't return for the next couple of days, after which 1.03 became available.
It's nice not having to guess now which dial is for shutter speed and which is for aperture when shooting in manual mode! Response time to changing those settings is now as fast as it was on my D700. Dunno if it's an intended benefit or just a corollary effect from the new firmware, but I'm also getting significantly improved battery life.
The one glitch that didn't go away is that the shutter will not fire after an adapted lens is mounted, not even when "Release w/o Lens" is enabled, and not on any focus setting. As with 1.02, shutting off the camera, removing and replacing the battery, and restarting the camera fixes this. Not a big issue for me, though, as the 3rd-party lens in question won't be in my arsenal much longer.
Having the semi-programmable buttons makes adjusting on the fly almost 100% one-handed. My one wish is that peaking color could be one of the programmable options.
While the measurebators have been discussing, dissecting, whining, and pounding their keyboards about noise at high ISO, I've been in the field shooting at the other end of the spectrum--ISO 50--nuking my tiny subjects whenever I need to. There, the image texture beats even the much-vaunted D700. And with a good chunk of glass mounted, detail is at least as good as, maybe better than, what I've seen from a couple of MF sensors.
As I said in an earlier post in this thread, whether gear is good or not is--in one sense--subjective, depending on whether it's good at what one wants to use it for. Maybe the a77 isn't the best camera on the market for the folks who spend all day doing 100% crops of test patterns shot at ISO16000. But for a real-world bug-and-flower shooter like me, it's the best camera I've ever had my hands on, even better than my beloved D700, which I shot for almost two years.
The pundits and pipsqueaks can keep on bitching about the few things they think the a77 can't do; I'll be enjoying all the great things it can do.
