Most of my pictures were made at f/1.1.
Of course (well except for those stopped down). In this kind of thread it's completely normal that we'd see a lot of f/1.1 pictures. Then again, at least my personal experience is that I'm not exclusively using lenses wide open.
No Nikon SLR is nearly as compact or handy as an M with the Nokton 50mm f/1.1 or produces the same quality.
I don't have the two for a side-by-side comparison here, but now that you ask I've just run the numbers through Google and it seems that with this kind of lens a rangefinder really doesn't have much of a size advantage anymore:
Rangefinder: Leica M7, Nokton 1.1: body 138 x 79.5 mm, total depth 95 mm (38 body + 57 lens), weight 1040 grams (610 + 430).
Personally I use an M5, but it would have been a little unfair to use that as a baseline.
SLR: Nikon FG, Nikkor 1.2: body 136 x 87.5 mm, total depth 101 mm (54 body + 47 lens), weight 870 grams (490 + 380)
The SLR combination is slightly higher (however, only in the center because of the mirror box). The lens protrudes more, but only slightly so. Both lenses are about equally fat. The rangefinder combination is about 15% heavier than the SLR.
Incidentally it would work with a Canon, too: AE-1 with nFD 50/1.2 L: body 141 x 87 mm, total depth 98 mm (47.5 body + 50.5 lens), weight 970 grams (590 + 380). Note that this is with the "L" version; the non-"L" f/1.2 lens is smaller.
The rangefinder lens is a quarter of a stop or so faster.
However, I think this kind of exercise in numbers is actually quite worthless. It's much more a question which particular lens one likes better and which style of focusing one prefers. The lenses are decades apart and quite different. For example I dislike rangefinder focusing for long lenses and for fast 50s because for me it feels comparatively inaccurate to a good SLR focusing screen. With wideangles it's different, which is why I use rangefinders for those. YMMV.
Your opinion about the 35's is totally unclear. Please explain what you mean.
I mean that I found the output from the 35/f1.2 Nokton wide open
much more appealing than that of the 35/1.4 (confusingly also named Nokton, hence the unclarity) and also better than the 1.7. Between those it's not just a question of shallow DOF. Between the 50/1.1 and 50/1.5, for example, I'm under the impression that it is.
Then again, most of the shots here are scanned and scaled down to the extent that the difference between f/1.4 or so and f/1.1 would be pretty hard to visualise. Seeing how scale, viewing distance etc. enter into all the equations on DOF calculations, it would be interesting to run the numbers for the circles of confusion: if you're looking at a 950x700 or so scanned image on an 17" screen viewed from 70cm away or so (the configuration I'm looking at right now), what's the minimum aperture where the DOF difference in a 50mm lens can be physically displayed?
Never heard such nonsense.
If this is already how you go into the discussion I don't think there's much confidence to be had in the remainder of it. If you like your lens, nice for you, you made a good purchase. Personally after looking at quite a number of shots from the lens I'm not as convinced as you are. That's just fine, tastes differ, I'm not attacking you.
The Nokton is a very good lens from a technical point of view; outstanding, probably. I'm not doubting the technical achievements, but those are hardly surprising again, after all the design is 30 years or so younger. Personally it just doesn't look like it's doing anything that for me would make it worth the $1100 or so.
