Thanks to Kristian for sharing this. Some of the used gear probably will never end up in most people's hands, so it's fantastic to see, what these lenses look like (and who the f cares about laboratory approved rigging - seriously be grateful for what you got to see and stop moaning this and that).
Does anyone here own the Nokton and uses it on an M9 or Monochrom? I've been sitting on the fence about buying one, as the Noctilux is out of reach at the moment (spent all my $$$ on the Monochrom!).
Regardless of its more affordable price, is it a good lens?
Vince, I can't help with the Nokton, as I didn't shoot one long enough to get a opinion on it's imaging but I do have a 50/1 v4 and an older v2 50 Summilux and can tell you, that they share a lot of similarities in rendering @ƒ1.4 and ƒ2.
If the budget isn't covering a Noctilux, a v2 Summilux (in any of it's many guises) is a fantastic lens, to use instead.
As I commented - similarities.
You won't get the shallow DOF, if that's what you're after, you won't get the 1 stop more light (with the Mono though I find, that ƒ1.4 lenses really allow to shoot in the deep night, where the Noctilux was my most used low light lens on the M8 and M9).
You won't get the look with strong vignetting, as any of the ƒ1 Noctilux lenses will give (and no, this specific look cannot be done in post processing, one can only ape it, if that's, what is wanted, but it will never look the same).
The files though have remarkable similarities in detail and rendering, especially around ƒ2.
You won't get the very smooth background rendering with the Summilux - it somehow seems more distracting @ ƒ1.4 (which is, where I don't like the v2 Summilux lens actually - the v2 Summilux really, really sings @ ƒ2, where I just adore it).
