Nippon Kogaku W-Nikkor•C 1:2.5 f=3.5cm RF lens in LTM vers.

Just found that neat lens, in the rare Leica thread mount (LTM) version, a 6e/4g design:




(Uc) Taunusreiter.de [this is the Nikon bajonet mount version, but optical the same]

This is mine:



Anyone has experience with that one?

The image is broken (so we can't see your lens )
Wish I had your connections, so you always post so many rare lenses (not that I could afford any of them I guess... )

[kds315*]

Fixed it. Well, it is not connections, more passion + patience

I have one. Got it a month ago or so and have only done one test roll of HP5.
It's a nice little lens with some interesting personality. The optics are the same as my Nikonos 35mm f2.5 which I use a few times a year.
The lens shows a fair bit of swirly oof area at wide open and some heavy vignetting when in close.
I don't consider this a bad thing. As you stop down or move away it tames up quite well.
Remember the following are a first test roll. Shot on M5. I guess most guys here would use this lens on a NEX or M4/3 and shoot digitally.
It's not very expensive when you find one expect to pay $200-$300. I paid $250 for mine with case and caps. It's mint.

Here you can see another finish variation of the lens mounted here on a Canon7 LTM RF. The Voigtlander "push in filter" is 32mm.


W/O at 1meter It is wild and vignettes about 2 stops by the corners



Here at f4 it is much more tame again at 1M.



Here at 1.5M the swirling is not as bad but vignetting is still 1.5 stops or so.


F5.6 well under control


f2.5 at mid range


f2.5 near infinity

Thanks a lot Andy, that's very helpful! I have the older version, all chrome, surely not mint,
but haven't payed much for it. Do you have Rotoloni's book? I wonder how many were ever
made....

[F16SUNSHINE]

no problem Klaus. I added a few more. I'll take some "Real" Photos with it this weekend. I like the lens.
I also have the W Nikkor 35 f1.8 which is much more rare and 10x as expensive for a mint LTM copy.
The f1.8 is a really sweet lens also but, it has some of the same "flaws'' at larger apertures.

[kds315*]

These add. ones look really good Andy! The f1.8 surely is a nice one,
but I wasn't really willing to throw so many g's toward one

[F16SUNSHINE]

What I liked about the lens in samples I saw before buying was how well it holds together highlights and draws tones.
If you look at the infinity shot you can see nice tone separation way into the distance. The leaves on the trees showing varying brightness.
A higher contrast and or sharper lens would blot those little details out.
This is a B+W film shooters lens in that way. I'm not sure how excited a digital color user will be with the results although, contrast is easier to add than to take away
Curious to see your result. Are you getting back into RF's Klaus? Good for you!

[kds315*]

Indeed, that I also saw. I'm not afraid of a low(er) contrast lens, it's worse
the other way round (the Apo Rodagon D is a horrible example for that!).
Yep, it seems the RF virus has hit me again Still feeling good!

Hello Tom

Not t hijack the thread.

The Nikonos 35mm f2.5 is the same optical scheme as this LTM lens and the Nikon RF mount lens.
I use mine in wet or "Adverse" conditions never have put it under the water .
It's a scale focus lens on the Nikonos but quite easy to use and handy.
if you have a Nikonos and 35mm in the attic you should pull it out and put a film in it.
These are film lenses for film cameras. Never mind adapting it. I don't think it's worth the trouble to be honest.
Have fun!

[Ymmot]

sorry, it was not my intention to hijack the thread , just got a bit too excited, guess there is some passion left here too .
I will put some film through it, thx.
I indeed found a manual for it that shows the optical scheme to be the same:
