Welcome. I haven't posted picutres in a while, and have to remember how to link pictures from Flickr all over again.

Every year around this time I get on a fast lens kick, so have been experimenting with various 50's. I'm looking for 1.4'ish, but always get curious about the f2 Nikkor again. I took it out today and shot a roll back and forth with the 50 Summarit 1.5 lens with both shot at f2. I just looked at the negs and am heading to the darkroom to make some prints.

I thought the Summarit at f2 would be substantially sharper and contrastier, but any differences aren't all that obvious so far just looking at the negs with a loupe. Backgrounds do seem smoother with the Summarit, but I'm not sure I won't prefer the Nikkor when I see the prints.

There are not many index marks in this close range, so using the red focus scale for accurate close focus seems improbable. The focus cam keeps moving as the lens focuses closer, but uncouples from the M-mount camera (I have tried a few) at the end of the first focus scale. Is this the normal design for this lens? I am a bit mystified at the purpose of the close focus capability.

Cheers,

I also have this lens and have been using it on my Tower/Nicca Barnack clone. I am wondering if anyone has tried the close focus capability on a digital camera and how well it works?

I have w/an M 240 using live view & it works fine (same goes for the 5cm/1.4 Nikkor-S).

My AI'ed Nikkor-HC 50/2 (F-Mount) is my main walking around lens. I took all of my film shots on my recent Israel/Palestine trip through it. It's just so... creamy.

Can someone confirm the pitch of the 40.5 thread please? There seems to be conflicting opinions on this.
Thank you

Thank you Erik, are you referring to 0.5 or 0.75 when you say 'old'?

I really don't know, but I had a lot of trouble of finding a fitting shade for the lens. Finally I found a plastic Nikkorex shade with a chrome fitting for the Nikkorex 5cm f/2.5 lens that fitted well. Very nice shade that also fits the Nikon rangefinder version of this lens.

Hmm -- my Nikkor-H.C 50/2 LTM has no trouble mounting a modern generic 40.5mm screw-in hood. Maybe Nikon changed the thread pitch at some point?

That's what I'm thinking. What number is yours?
I'm hoping to be able to use screw in Heliopan filters and hood with 0.5 pitch.

Mine is s/n 742925 (pretty late, with black aperture ring).

From recent information the optical formula of the Nikkor-H 5cm/2 did undergo some changes during it's production.
The Nikkor-H 5cm/2 was originally designed in 1946 using German Schott "barium" glass and a collapsble mount.
When the new Nikon 1 camera was produced in 1947 a very small number of these cameras were fitted with Nikkor-H 5cm/2 lenses serial nos.609xxx.Due to the stock of German Schott "barium" glass running out Nippon Kogaku had to re-design and re-formulate the Nikkor-H 5cm/2 using "non-barium" glass that they had in stock as they were not allowed to produce their own "barium" glass because of restrictions made by the Occupation government.This series of lenses was the 708xxx and was supplied with most early Nikon 1 cameras.By late 1948 to 1950 supplies of newer glass types became available and presumably the 5008xxxx series in a fixed mount stabilised the design for the later series of Nikkor-H 5cm/2 lenses.

I recently read about this in ニコン物語 (Nikon Story) and 明るい暗箱 (Bright Dark Box), which are the two most detailed books in Japanese on Nikon's early history. Its true that the optical formula of the Nikkor-H 5cm F2 did go through some changes very early on in its production cycle. Different glass had to be used for one particular element, so the design was tweaked to accommodate that. I'd have to go back and reread the sections again, but I don't think the story above quite fits what is written in these Japanese books though.

Unhappy

I recently found a nice Nikkor HC 50mm f/2 in LTM and I am quite happy with this lens.

However, the filter thread size is a mystery to me. I tried 43mm, 40.5mm, 40mm, 39mm, but none of my filters fits. I guess there is some kind of special filter needed. Hmmmmm, can anybody help me?

40.5 but a different pitch. Hoya filters should work; B+W filters are not so tolerant.

40.5 mm diameter with a 0.5mm pitch.
B+W filters work fine on mine.

I found that the F-Pro were not loose enough; the old school front loaders, more.

Using F-Pro on both my 50mm f2 and also my 50mm 1.4 although the 1.4 is a larger diameter of course.

I had no problem with a B&W 40.5mm filter on my Nikkor 5cm f2 lens on the Nikon S2, but it wasn't an LTM lens. Maybe the thread diameter is different on the LTM version of the lens.

Maybe some were different or possibly a damaged thread?

Thanks for all the replies, but now I think that my problem is sligthly different. On my sample, the aperture numbers are quite at the top of the lens body. In pictures that I googled I can see that other Nikkors have a slightly "higher" lens body with a filter thread, as for example as in the picture in this posting. It's not clear to me if there is something wrong with my lens...??

At least on the 50/2 with black aperture ring there is a metal ring in front of the aperture that easily unscrews, and sometimes the lens is sold without. Not sure what the thread size of that ring is.

Happy to have joined the ranks of Nikkor-H 5cm F2 owners (thanks to the Mod on this thread!). Have been scanning results from my first shots and hope to post something soon.

Are these ltm Nikkors different than their contemporary couterparts in F mount? (f/2, f/1.4)

Yes, they were Sonnar variants (same optical formula as the Nikon rangefinder versions), whereas the F mount 50s were more Planar(?)-like. The 5m/2 Nikkor-H was based on the Carl Zeiss Jena 5cm/2 Sonnar & the 5cm/1.4 Nikkor-S was based on the Carl Zeiss Jena 5cm/1.5 Sonnar (recall that Nippon Kogaku based many of the features on the Nikon rangefinders on the Zeiss Ikon Contax rangefinders).
