Whoa! As another R-D 1 user, I had been thinking the M8 was everything I ever wanted, and was scheming how on earth I could manage to buy one.
But now after reading Erwin's review (even the expurgated second version) I'm not so sure!
1) Yes, 10 megapixels would be great, and having framelines for 75mm and 90mm framelines would be nice. And as Sean Reid has pointed out, some of Erwin's initial negative comments were about characteristics that are partly determined by the firmware, and the test camera's firmware wasn't final. (These comments have been snipped from the reposted version of his review.) Perhaps the release-version firmware will be better. Still...
2) -- No exposure compensation dial? I use exposure compensation a lot. Having to dive into the menu system to get it would be a huge pain. There's no way to fix this in firmware.
3) -- There's some controversy on whether or not the M8 has more shutter-release lag than a mechanical M -- but there's no doubt that it needs a three-stage shutter release so it can incorporate the meter-on, AE-lock, and shutter release functions. Maybe going through all those stages caused the lag Erwin originally thought he was feeling (before this remark was expurgated from his review.) Meanwhile, other reviewers have noted that pressing the release just enough to lock AE can be touchy. I can't help thinking that the R-D 1's separate AE lock button is a better solution.
4) -- The original version of Erwin's writeup (before he removed anything firmware-related) noted that he was getting only 200 shots per battery. Crikey, that's not very good -- I'd need three batteries to get through a typical shoot. The R-D 1 is a bit of a battery hog if you turn instant review on, but if I leave it off I can get through a long shoot on one Epson battery. Let's hope Leica's final firmware is less power-hungry.
5) -- Holy cow, once the buffer is full it takes a full minute to empty it?!? This also was excised from the second version of his review. Again, I hope the final firmware does better -- no photographer is going to want to spend that long sitting in the "penalty box." I'm sure they can improve on this, but I still suspect there may be a speed penalty for choosing the computation-intensive DNG format for raw-file storage.
6) -- Leaving out the anti-aliasing filter sounds like a great way to get finer detail...until you look at the "Siemens star" photo in Erwin's test (again, removed from his reposted review.) The center of the star was pretty badly artifacted. I wonder how this is going to play out in photos of finely-detailed real objects with regular patterns in them, such as fabric textures...? Kodak's DCS14 SLR also dispensed with the antialias filter, and I recall some reviews noting problems with moiré patterns in such subjects. Again, since the M8 uses software-based antialiasing, maybe the final-version firmware will be better than in Erwin's now-removed test shot. But what if it's not? Leica's notion of the best tradeoff between fine-detail rendering and moiré avoidance may not be the same as my notion.
7) -- Come on, a $4800 camera and they can't spring for a PC outlet? (And before you ask "Why would anyone need a PC outlet on an RF camera?", let me answer by saying that an RF is great for studio shooting with an AC-powered electronic flash system; one big advantage over an SLR is that you can SEE the flashes go off through the viewfinder, which makes it a lot easier to coordinate action shots.) Sure, you can put a slave trigger in the hot shoe, or use one of those cheesy hot-shoe-to-PC adapters, but it still seems a little chintzy.
8) So, one good thing about all this is that it makes me feel a bit better about the fact that I'm going to be sticking with my R-D 1 for quite a while! If I encounter some bucks-up photo snob who wants to know why I haven't traded for an M8, I no longer have to say, "Because I'm too poor"; instead I can say, "Yeah, it sounds good, but for the way I shoot I really kinda need a hardware exposure compensation dial and an AE lock button."
