I must admit I'd be a bit concerned about buying a camera which has been on the market for quite some time and is of such a high price where it only appears as though most of the known issues "are being" resolved - I'd wait until they are resolved, or see what the M10 has in store for us and at what price.
I started shooting digital in my work when the Nikon D1 came out. That was about twelve years and I have yet to see a digital camera that didn't initially have problems. The D1 had many issues and at that time the camera had to go back to Nikon to have firmware updated. Nikon didn't get things right till the D1x which I bought and that too had problems. Leica is just trying to get their digital legs under them. This is why I didn't buy one until now. I suspect the M10 will have its own issues and take a year or so to iron out. When they get fixed I may upgrade if the camera offers something I want.
I've been very lucky I guess. My new D800 has been flawless but there are known issues.
Yes I feel the ZM lenses perform better wide open compared to the ZF 2 on the D800. I bought the 25/2, 35/2 & 100/2. The D800 is brutal on lenses. The 100 was amazing at all apertures but from f2-4 there was terrible aberrations with smearing purple fringing around bright contrasty areas like leaves against the sky. I've never seen it so bad in any lens. It correct well inLY4 however. The 25 was terrible in the outer 1/3 wide open and e en extended into the inner area. This improved by F8 but never disappeared. The edges and corners were unusable at wide apertures. The 35 was quite soft in the outer 1/3 until f5.6 and became good. It was. Ever as sharp as I expected. It was acceptable but. It up to the cost of the lens.
I have a Nikon 16-35 f4, 24-70 f2.8, 70-200 f2.8 VRII, 85g 1.8 and the 24 & 85 pc lenses. Every one of the Nikon lenses performed at least as good if not better as the Zeiss at the same apertures. It was like they were f8enses not f2. I need lenses that are usable wide open.
My medium format digital is A Hasselblad V system with all current Zeiss glass. I use the CFV39 back and all of my MF glass performs quite well T max apertures. They do improve a little when stopped down but they're excellent wide open. This is what I expected from the ZF glass but didnd get.
Let's hope my M9 is a good one.
If Zeiss lenses need coded who do you send them to? Is coding with a pen ok? It's the back focus correction driven by the menu lens selection too?
Many thanks for all the info
