Lovely! I own a GR1s and I'm convinced this new digital GR could complement it very nicely.
What's your initial impression on the AF speed?

The AF speed feels slightly faster than the X100s, but that is purely a subjective opinion as I did not have both cameras side-by-side to compare. Probably because it is a pre-production unit, the macro focus wasn't able to engage properly, so it could indicate the normal speed focusing speed wasn't optimized yet in the pre-production unit. Right now it is not as speedy as say, a Sony RX100. But the focus speed compares favourably to many other compacts out there.
I only had the chance to try it over a coffee session, but I might be able to shoot with it tomorrow. If that happens, I'll share more details about the performance here.

No way this is faster than "world's fastest AF*" /kidding
Did you asked for the latest firmware? I remember someone mentioning that the latest firmware fixed some problem with macro focusing distance.

It's really very similar in dimensions to the GR1V, just slightly heavier. We are talking about millimeters of difference here, so it's an amazing job that Ricoh did in squeezing an APS-C sensor in there!
Hmm... I don't know about 'amazing'...
Ricoh was able to "stuff" in a full frame "sensor" in GR-1.
Years later they are able to put a smaller sensor in a slightly larger body 🙂

Unfortunately I didn't check on the firmware version... nonetheless it should be a simple issue to resolve and I'd be absolutely shocked if the production units have the same issue!

Make that a full frame 'sensor' & an optical viewfinder!

what i don't get is why the diameter for digital lenses is so much larger than for film...what are they putting in there?

I'm curious about that as well... Anybody knows?

The larger the size of the lens, the more you can charge from people -- Unless you're Leica.

It's all about designing a lens that causes light to hit a digital sensor at right angles. If it doesn't, it causes bad vignetting, hence the development of microlenses that channel light into the periphery of the sensor in Leica, Fuji and Ricoh cameras, and why even now the M series has lens coding for vignette correction.
Generally, lenses need to be larger to channel the light for digital sensors. Film doesn't have this issue and lenses can be a lot smaller. My expectation is that a combination of new sensor tech and microlenses will allow much smaller lenses to be used, but that day is not here yet.

Haven't been able to read it in-depth yet, but even-if, it's still a > 30% price difference!

Oh no! He's wrong! 😱
Seriously though, that was one of the best previews on the GR I've read so far - very informative and no biased BS. I didn't get the impression he considered one or the other superior. His comparison of those two cams comes tomorrow, let's wait until then.
P.S. I'm not even considering the Nikon, just curious 😛

This is very cool: Ming says that both the Nikon A and GR are at least the equal of the M9 + 28mm Elmarit in technical quality, and almost as good as the M240. This is huge news for me, because I really want a camera that I can carry in lieu of the M9 and still be happy with its image quality. Yesterday I was out with the M9 and OM-D and feeling the bite of the bag strap as I walked around. Something like the GR in a pocket would be an absolute boon.

I'm still very much on the fence. The GR looks to be a bit better but I already own a Nikon flash. Also VSCO as they are far more likely to create custom camera profiles for the A.

Since the receptor in a sensor (photodiode) is a well with 3D depth, light must hit straight on to fill up the well, unlike film which can handle a degree of obliqueness and still react photochemically. Film is just more tolerant of light striking at an angle because it is flatter, being so thin that even oblique light achieves its purpose...to point. Sensors require a perpendicular light path to the sensor plane and are much less tolerant of obliqueness.
To get a straight ahead light path the lens on a digicam it is necessary to engineer wider lenses than 135 equivalents. Or make the sensor smaller. Or recess the sensor slightly in the body compared to film. You really see this on the Sony RX-1. Huge lens compared to many film era f/2 offerings. Then again, even with supporting electronics and rear screen, losing roll film space allows for a relatively tiny body.
Even a wider lens mouth is not enough, particularly on wider angle optics. That's why sensors have micro-lenses on their forefront plane:
