Yesterday another lens arrived and was tested as working fine:
Voigtländer Color-Heliar 75mm f/2.5 (Leica LTM screw mount, using an LTM to M adapter)
It's a very nice lens. The size is comparable to the Zeiss 21mm ZM, but at 230 grams, it's about 50 grams lighter. Mechanically, it's on par with the Zeiss lenses. Focusing is very smooth. I actually like the ridged focusing ring better than the tabbed Zeiss one. (It's probably a left-over from how I was used to zoom and focus using Canon lenses, seeing that most rangefinder people *demand* focusing tabs...) A difference to the Zeiss lenses is that the C-H 75mm f/2.5 has half stops for it's aperture ring, while the Zeiss lenses have third stops.
It starts out sharp at f/2.5 already. The lens does not need any sharpening, or only a little bit, when used on the AA-filterless GXR-M.
According to reviews the Summarit 75mm f/2.5 is even sharper in the center, but the Voigtländer seems to have a better control of purple fringing. The Voigtländer also is about 100 grams lighter. It's price of €425 makes it a steal compared to the Leica, which comes in at aroud €1275. It's A pity that this lens is out of production. The new version is the Classic-Heliar 75mm f/1.8, but that extra stop makes it much larger, almost twice as heavy (427 grams), and more expensive (€ 629).
Very happy with this lens with regard to price/performance ratio, even though it has a "strange" 112mm FOV on the GXR-M. Luckily I know the FOV from using the 70-200 on Canon
