Ultron 40mm f/2 versions

[sanmich]

I became interested in this lens, but can't really understand the different versions.
I think there are at least three of them based on their focus ring: 1- chrome, 2- rubber, 3- scalloped anidized

Are there any differences other than cosmetic?

incidentally, what is your experience with it?

That's correct, there's three different versions of barrel, all with the same optics. The "SL" chrome ring and bayonet hood mount version (and rabbit ears in the case of the Nikon F-mount version) was first, then it was replaced by the "SLII" rubber focus ring version, which was then replaced by the "SLII N" knurled metal focus ring version.

I can't tell you how it performs as, while I've used several Voigtlander SLR lenses in other focal lengths, I've never used this one. Seems highly regarded though.

I have the first version, which I prefer as I need the meter coupling for my FTN meter. It is very sharp, and distortion free.

In fact, it replaced all of my Nikkor 35mm lenses:
1.4 AIS, f/2 AIS, and 2.8 AIS.
It replaced my Nikkor 50mm f/1.8 AI also, as the contrast is greater wide open with the Voigtlander.

AFAIK, all versions have the same optics, just different cosmetics.

I loved this lens. I think I've had the SLII version. Wonderful craftmanship, great optics, essentially flare-free and distortion free, super-sharp. Lovely. I've sold it only because I got rid of my Nikon FX gear. I recommend.

There is a major difference between the SL1 and SL2 versions, and that is the SL2 versions are chipped so they can be recognized electronically, and have the aperture controlled (when set to min value) by compatible cameras such as the Nikon F6, and countless Nikon digital cameras.
Optically they are all the same and fantastic. The only difference between the two SL2 versions is the shape and construction of the focus ring.

I have had all three. Yes same optics which btw is about the sharpest lens I have ever seen on a Nikon.

Maybe worth noting is that the SL series of lenses was originally made available in about half a dozen different SLR mounts...Besides Nikon there were Olympus OM, Pentax KA bayonet and even Pentax M42 screw mount. In each mount, they were made so that the focus and aperture controls rotate in the direction common to that brand's own lenses.

I have the original SL for Pentax KA mount. Suggest you could do a search for this lens in the RFF Gallery, and find some samples.

Here it is on a Pentax LX...
