is there and m-mount RF 50 close in "look" to what you get with your SLR nikkor 50/2?
i don't know anything about lens formulas and other tech stuff. i do very much care to read your subjective opinions on this.
thank you much ahead of time.
 
The 50/2 Nikkor is a Sonnar design. I am not sure that there are any M mount Sonnar lenses, but it is easily used on an M camera with an adaptor.

+1. Just use with an adapter. I see absolutely no downsides to using an LTM lens with a quality adapter.
 
The RF Nikkor 50/2 started out as the spitting image of the Zeiss Jena Sonnar 50/2 - but as either were only made in LTM and the former is more easy to come by, there is little point in adapting the latter.

But being in "SLRs", Paul probably meant the SLR 50/2. Which is a double Gauss design. The f/2 Summicron-M is pretty similar in design and results, but better coated and hence more contrasty than pre-MC versions of the Nikkor.
 
yes, the SLR nikkor 50/2. mine is a later one with multi-coating.
i understand there are formula/design differences between slr and rf lenses.
that is why i am seeking subjective opinions from you nikon slr fans who also are RF users.
it is the nikkor 50/2 "look" i am after in a 50mm lens for my r2m.
 
with the same film and developer and similar subject, the skopar showed less tonal range than the nikkor; the skopar seems to have more contrast. this may be a coatings thing.
 
Yes, you're probably right. The later coatings will have more contrast.
I think other than the earlier Summicron you will be choosing from LTM lenses rather than M mount.
Then look for single coated lenses with Double Gauss schemes.
Canon 1.8/50, Yashinon 1.8/50, Summar 2/50 (might be a great option for you) etc..
The Nikkors LTM's 50's are Sonnars rather than Gauss. My favorite though not the same look as your nikkor 2/50.

Since Nikon has always favored the Zeiss look, perhaps the ZM 50/2 Planar.

I was going to say Canon 50mm 1.8 though the Yashinon 5cm 1.8 is very similar. Basically a planar/gauss lens from the 60-70s would probably have similar characteristics with slightly less contrast than a new lens. I'm sure there are others but those are the only two similar lens I have personal experience using.

I'd steer clear of the Summar as that look is a bit more extreme than what you want, from the sounds of it. It can be a great lens but I won't really compare it to the Nikkor as it has a very different look.
 
The last Wetzlar 50 Summicron version (1969-78) is the closest according to Erwin Puts. Both are double Gauss designs made around the same time. Each relied on modern computer designs to optimize contrast over resolution. The Nikon F version of the 50/2 Nikkor is a straightforward 6/4 design much like the Canon 50/1.8 FL, FD and current version. Camera 35 magazine once tested the Summicron against the Nikkor and Canon FL in addition to other Japanese 50's. The Summicron scored a bit higher in resolution than all the others as I recall. I've used them all and the Summicron has IQ exceeding the 50/2 Nikkor or 50/1.8 Canon wide open or at f/2.8, both are a little soft and come into their own by f/4. Neither are bad, just not as good as the Summicron.
 
The SLR Nikkor 50/2 is a 6 element double Gauss.

Most similar are other 6 element double Gauss designs, for example Summicron v3 and v4, Canon 50/1.8 and 50/1.4, ZM Planar, M-Hex. Probably the Summicron v3 & Canon 50/1.8 are most similar due to speed and coating technology. Note that the Canon was built for 20 years or so, so you have to pick the right period for a good match.
