Yeah, lens brothers!
CV or VC.... I see both. I guess I over on the Leica M8/M9 thread I picked up CV and stuck with it.
Michael: I think Cosina calibrated to f/2.8 because it's probably the middle point for the focus shift before depth of field masks it. If they calibrated it to f/1.8, then everyone would complain that f/2.8 and f/4 are back focused. You're a Nikon user, so might not be familiar with this, but over on the Canon forum, the 50mm f/1.2L has been repeatedly trashed for this. Another consideration is the Zeiss ZM 50mm Sonnar. It also has focus shift and was originally optimized for f/2.8 when it was released, which probably works great for film users. But I think a lot of digital users eventually complained and my understanding is that Zeiss (well, actually Cosina) now optimizes it for f/1.5. Maybe Cosina is being old school with the 75mm by choosing to optimize for f/2.8. BTW, I don't know they've done this with any certainty, but it makes some sense.
So I received the 50mm f/1.5 this evening and I guess will give it a try over the next few days. I definitely see purple fringing from it... So far compared to the 50 Lux ASPH, the CV has a more lively background bokeh rendering, though foreground is smoother and more like the Lux, which is overall very neutral. It seems like a pretty sharp lens wide open...
Michael: yes, the 50 f/1.5 was discontinued a while ago, though Cameraquest still shows some stock. I just happened to stumble across this one used at Robert White in the UK for £300 in mint condition. I've seen it on various buy & sells for around $600 in similar condition. I think I will prefer the 50 Lux on the M9 but really picked up the CV50 for use on the GXR as a smaller fast 50 alternative to the Lux, which I don't like as much on the GXR crop.
Regarding the 35mm f/1.2 v.1: It has a reputation as being a lower contrast lens, so compared to the ZF lenses, I would think it's more the lens than the camera, though the M9 by default is probably a bit higher in contrast than the D700. The lens's contrast should also drop a bit more the closer you are to minimum focusing distance. BTW, I really like the rendering in both of those images.
