I bought mine from www.speedgraphic.co.uk about 3-4 months ago. Cost was about 30 GBP (excl. delivery). I've just checked and they don't seem to be selling them now. However a quick ebay search for "Kood + Nikon" reveals a couple - again for about £30 GBP. The adapter comes with a cap and "spanner" (not shown above).


Hi Sichko,

is there any magnifying factor involved with the use of glass element in those kind of adapters? For exemple, a 50mm lens become a 60mm (1,2X factor) or stays the same?
Thanks.

Great Bothanic Gardem and gogeous shots. One day I will do something similar!! Very Happy

I have a similar image from Phoenix rupicola (Cliff Date Palm), it was take at my Bothanic Garden.

I will try this adapter. Thanks for share the information.

Good stuff John, the Jupiter 37A is one of my faves, you do it justice here. I have adapted mine as others have suggested with a Pentax-k t2 mount and it works perfectly, money permitting I am planning to do the same with all my Russian 'A' lenses.

Hi Gaetano. thanks for resurrecting an 11 month old thread ! One of the suppliers (srb-griturn) suggests a factor of 1.2 exactly as you suggest. I prepared a calibration curve by photographing a metre rule at different focal lengths using a 55-200 zoom. Using this curve I estimated the 135mm + glass adapter to have an effective focal length of ~ 150mm suggesting a factor of ~ 1.1. This might be an advantage or disadvantage depending upon your point of view. I later acquired a 120 mm lens and convinved myself that the EFL of 150 mm was more useful than the native FL of 135 mm. |However, as Poolhall suggests a T2-adapter based mount is better in some respects.

There was a forumer many moons ago that posted some Nikon+Kood
adapter shots, nice focus and sharpness to the images. Don't know how
I missed this thread, but those are some lovely shots, Sichko!

Sichko, thanks for the time you spent with lens and adapter, trying to find the effective multiplying factor.

I'm really surprised you got such nice results with an adapter. My cousin tried something similar and had terrible results. Nice work.

Thanks for your comments. I bought the adapter early in my MF career when I didn't know much about these things. I think it was suggested by a staff journalist (with a serious photography background) on "Amateur Photography" - a UK weekly. I think that I must have been lucky because there appear to be a number of different makes of "glass adapter" and some of them are not so good - as Ron's cousin's experience indicates.

There are a few threads on the Nikon-M42-glass adapter debate on this forum. I don't think that I'm the only one who has had good results with the Kood adapter. And other forum members have recommended one made by Bower.

The adapters I've heard woes about are of Chinese manufacture, where
the optics were not the same quality as the Japanese Kood. And I'm not
out to bash Chinese products, either.

I've just had a copy of the Jupiter 37A turn up, using it on a Pentax K20D with the Pentax M42 adapter it performs quite nicely.

I have done some research in M42/Nikon adapters again, and I´ll give you a short update:

- I´ve got one of these KOOD adapters, too. I´m not so happy with mine, the glass lens makes a pretty cheap appearance, and there are many glares and glow on contrasty edges, especially at open apertures.

- The KOOD adapter indeed is PERFECT for mounting Mamiya/Sekor SX lenses. The aperture ring doesn´t get stuck because the diameter of the adapter is smaller than the clearance at the lenses back. The top of the lens exactly reaches 12 o´clock position when screwed in.

- The aperture doesn´t work with this adapter, as the aperture pin isn´t pushed. But I have solved this problem by putting a hard rubber seal (initially bought for the dish washing machine Laughing ) into the KOOD-adapter. It fits perfectly. If you are looking for something similar, it should be max. 40mm (outside) and at least 31mm (inside), and appr. 3mm thick.
Now I can use the aperture ring on my SX lenses, it works at all F-stops. Of course the viewfinder gets darker now when stopping down, but this doesn´t bother me at all.

- Focusing is still difficult. The D50 doesn´t have a great viewfinder, and the electronic focus indicator - which works just great with old Nikkors - seems to be distracted by the adapter. So it indicated correct focus not just in a single spot, but in a certain range of a few degrees when turning the focus ring. This makes things pretty hard, especially at low light.

- Real infinity focus doesn´t seem to work, when I put the lens at infinity focus, rooftops in 25m distance are sharp, but not the trees at the horizon. I feel this is a bit strange.

Here are two example shots with my SX 28mm F2,8 at F5,6. In the first, I got close to focusing the branches correctly. In the second, I completely messed things up, because I wanted to focus on the star, but you know, this indicator thing... So in fact, the focus is now on the side window of the balcony.

A link to the full resolution image is below the 900px version.

I´d like to know what you think. As far as I am concerned, I just admire those colours. They are so intense and dreamy, and completely different from all of my Nikkors. I didn´t use any post processing at all.

Richard - in connection with the mount I'm not sure what you mean by "A series". Is it the "A" in Jupiter 11A, Jupiter 37A, etc. ? The 11A and 37 A certainly seem to have identical mounts. I actually tried this idea a few weeks ago with an 11A. I had an M42 T mount from a PrinzGalaxy. I removed the insert (which had the T female thread 42 x0.75 mm) and was left with the M42 "collar" with the 3 grub screws. Unfortunately this collar wouldn't fit over the end of the 11A (after removing the original M42 mount). Looking on ebay, at pictures of Nikon T mounts, I think that I'll have the same problem with a new mount.


To be aware that M42 T mount adapter in the market having 2 sizes of "collar" (inner daimeter) depend on its manufacturer.
So you have to know which brand name having smaller collar that can fit to "A series".

This type should fit..

Click here to see on Ebay

... I bought a Nikon mount from the same seller. It was identical with the one in the listing except that it didn't have the name "KOOD" printed on it.

I also obtained an identical mount from speedgraphic...

If you carry out a search on this forum you will find several discussions and sets of pictures.

Hi guys, I'm a newcomer to a old thread but I noticed that sichko mentioned that he received a Helios 44M alongside his Jupiter...

Just wondering whether any of you have managed to use the Kood/Nikon adaptor you discussed here with any of the Helios 44 variants? My understanding is that you can't use an optical type adaptor with lenses where the rear element protrudes beyond the M42 screw thread, and I believe from various sellers on eBay that the 44s all protrude by a couple of mm...

I'm hoping this is a myth (!) but would love to hear from any of you if you've tried fitting a 44 to a Nikon... I'm desperate to get some fast-ish portrait glass for my D100 but I'm on a very limited budget.

Thanks...

(PS I have, of course, been looking out for Ai/AiS Nikkors but they don't seem to be going quite so cheaply...)

Being a Canon shooter I don't need glass adapters, but wanted to say welcome to the forum!

Thanks Martin... I love my Nikon but I'll admit there have been moments, trawling the internet late at night looking into this topic, when I've let the odd "doh!" slip out... Wink

After reading this note, ordered in http://www.speedgraphic.co.uk/ Kood body adapter.

Sent some Chinese forgery. Terrible quality of the lenses. The claim said that Kood adapters do in the far East and are the most cheap for the quality. Therefore, it is very strange that you write here and give positive feedback. Very disappointed that I spent time on purchase of this shit.

If it was a forgery why didn't you return it it ?

I reported what I saw. I obtained results of similar quality using the CZJ Flektogon 2.4/35mm and a couple of other M42 mount lenses.

You appear to be comparing my results, obtained with what Speed-Graphic describe as a KOOD adapter, with your results obtained with what you desribe as a forgery.

Again, if it was a forgery .....

The seller told, that this Kood body adapter, produced in the far East and cheapest option for quality. In other words, this is China, not Japan.
Other, apparently, they do not sell. And a link to this site I have seen only in your topic.
That is, if You bought this code on them, and then Your adapter cheapest option, as they say. And I wonder how You have it-a Japanese with excellent results?

Why not come back? Because I don't want to go to the post office and to do the transfer, it's time spent is more expensive.

P.S.
Why do you think that your code is not the same fake from China, if bought from the same vendor?
Isn't that the United Kingdom with the supply from China?
Probably because you are trying to dark glasses, so that the difference is not so noticeable, as fast optics.

In my case I encountered another and with the problem of focus in the viewfinder.

Somehow put the image in the viewfinder, with this lens adapter, I get the focus on the picture. With the usual adapter without lens, this effect is not.

Fujinon 50 1,4 + Lens adapter.


Fujinon 50 1,4 + without lens adapter

Focus was on average stick.
Why this is so, can not understand!

It is even worse than just bad quality of the image.
