Well, I've been using my M8 for almost 6 months, but...
(1) 6 bit coding is restrictive:
Let's face it, there are plenty of lenses from other brands we use.
There should be a menu option for us to input the focal length, just like the D200.
Perhaps a memory setting of 4-5 lens, so we can choose and set the lens name into the exif. I suppose most RF users have 4-5 lenses at least, a lens name input would be great!
I self-coded all my wide-angle lenses (permanently, milled wells for the black codes and painted them in) including a few screw-mount adaptors. Anything longer than 35mm doesn't need cyan correcting so I didn't and wouldn't bother with coding them. Once-and-for-all coding those lenses is a lot easier than changing a menu each time. Still, it couldn't hurt to have such a menu for those people who want it.
(2) My Ricoh GR Digital has an interval timer, I would love to have one on my M8.
This is really useful. I hang the GRD on my neck, set the interval timer to take one shot every 15 seconds, then I walk into the subway, taking photos by itself. Ultra stealth function!
Interesting idea, but I admit I would never use it.
(3) An external ISO button?
I have never used the 'protect' button. But I change the ISO very often.
Do you use the 'protect' button?
Perhaps Leica could let us customise a button to our choice?
I've never used the protect button. I also never change the ISO from 160. I found that "push processing" in ACR produces less noise. But since digital allows for ISO to be an adjustable exposure parameter, I agree it should be readily accessible--as long as it isn't also readily accidentally disturbable!
(4) The "film counter" is not backlit.
Couldn't Leica make a backlit LCD counter?
Beside, I wish M8 has a dial like the R-D1. Could you not admit the analog dial on the R-D1 is the most lovely display I have seen on a camera.
I've never found myself in complete darkness and needing to know how many shots I have left. I agree the analog dial display on the RD1 looks pleasing, but honestly I think digital guages are less prone to shock damage. Also the shot counter on the RD1 is very approximate due to not having enough markings.
(5) When is Leica fixing the white-balance?
This is not a critical issue, I can shoot DNG all the time, but Leica should still fix the white-balance.
I'm beginning to doubt they will ever fix it. Even with DNG it should work better than it does. No AWB is perfect, but the M8's is psychedelic
😱 Sure I can (and do) use manual, in fact I have a Minolta Color Meter and can set Kelvin temp if I want. But it's a head-hanging shame on such an expensive camera that AWB is basically unrealiable in the extreme.
(6) I am waiting for SDHC support.
Being of the don't-put-all-your-eggs-in-one-basket philosophy, and given the M8's slow motor drive, plain old 2GB SD cards work fine for me.
(7) Leica Digital Capture does not work in Vista.
Never used or thought about using Digital Capture. And I don't have Vista. If I move from XP it'll be to a Mac.
(8) I don't care about the IR issue.
I don't what the big fuss was about with the IR issues. I slapped a filter and use the camera. Everything worked out fine. Just go and buy a filter. This IR issue had me scared from buying the M8 from almost a year. In hindsight, this was really a minor thing.
Well, I had to
buy about a dozen filters (including some as spares because they're essential, not like a UV I could do without if it got scratched or broken). Then I had to code all my wide-angle lenses. Aside from that, now it's not much of an issue, I agree. It's still irritating in that excellent digital cameras from other makers don't have that problem...but they don't offer me the ergonomics of the M8, so I accept the issue and live with it.
(9) Last, I really enjoyed using the M8.
Do put out an M9 yet. Leica must take its time. The M8 is excellent already.
The simply DNG workflow into Capture One is already leathal enough.
I personally don't care if or when Leica brings out an M9, as the M8 does what I need from it. And the lesson I learned from the M8 is that I will wait at least a year after any future model's introduction before buying one.
