1] El-Nikkor Enlarger lens to Nikon bellows

Struggled with this for a few days, finally used parts that I had available. I'm certain there are better ways of doing this - let's see some Smile

A far more elegant solution.
I paid Can$20.00 locally for the T-mount adapter Sad .

Details? M39 - F mount and various iterations turned up nothing useful on EBay

Remember that even though these are enlarging lenses, is is advisable to mount them in reverse when using them above 1:1.

There are many Nikon reverse adapters out there (F-mount on one side, 52mm threaded on other side). Many enlarging lenses have a 40.5mm filter thread. My preference is to use a 40.5-52mm stepping ring (see eBay #110300237550) together with the above mentioned Nikon reversing ring. This makes a very nice arrangement. (If you are really lucky you might find a Nikon made "F-Mount EL-Nikkor Reverse Adapter")

The T-mount thread is M42x0.75. The "Pentax thread" that was once a common mount is the same diameter but a different pitch... M42x1.0

You can always find a good use for a T-mount. While not that common, it's not too hard to locate T-mount "reverse adapters" that have a male T thread on one side and a male "filter thread" (52mm, 49mm, 55mm...) on the other. See eBay item # 310083275474 (although seller does not state thread size) and item #91125 on this page: http://www.pacificrimcamera.com/catalog/cd31.htm

If you get hooked on this type of photography (and I think you have Wink ) you will likely try a microscope objective at some time, and you can get T-mount to RMS adapters that will solve the mounting problem with most objectives. (Edmunds Optical item # NT52-301)

So I'm pretty confident you will always find a good use for your Nikon T-mount adapter.

mgoodm3: my question was (and is) what did you actually order (part #?) and from whom in China (e-mail addrress? company web site?) .

Charles: yes I'm hooked. Thanks for the useful info. Have ordered the 42.5-50mm ring and the NT52-301 (plus some other stuff) and waiting impatiently
Yesterday I used the El-Nikkor 50/2.8 mounted normally (non-reversed) at about 2.9x mag. and am very impressed with the resulting image quality, certainly nowhere approaching your image quality but presentable.

I predominantly use enlarging lenses reversed for >1:1, but I also like to see how well they perform normally mounted. For $15 shipped, it's a no lose situation for me. This adapter doesn't fit onto my extension tubes (kenko), but does fit fine on my Nikon bellows.

I want to get a longer enlarging lens (~135) to use normally mounted as a bellows lens (like the Nikon 105mm short mount).

NU,

I'll upload some images of various EL-Nikkor configerations later today (Australian Time).

There are some differences in regard to mounting when dealing with the older (Mr Zenji Wakimoto) EL-Nikkors and the later (Mr Mori) EL-Nikkors.

Another link here to an older thread:

http://www.photomacrography.net/forum/viewtopic.php?t=3510&highlight=nikkors

Quote:
There is a difference in the filter thread size (34.5mm) of the older (chrome base) 80, and 105 ELs (not sure about the 63mm). The later versions have a 40.5mm filter thread - the same as the original 50/f2.8. This is important to know for reverse mounting.

Here is the EL-Nikkor 2.8/50mm reversed mounted.

Quote:
To enclose and protect the end of a reversed Nikon lens, EL-Nikkor or Micro Nikkor I use a Nikon BR3. It allows you to attach filters... To use the BR3 with a reversed EL-Nikkor you will still need the 39mm to Nikon Mount adapter.

Thanks Craig, proves the old adage "A picture (or 2) is worth a thousand words"

Your 50/2.8 differs from those of mgoodm3 and NU's - care to comment?


I have edited the Topic title to better reflect the contents of the discussion.

Perhaps someone will begin a new topic for another set-up.

There are two versions of the 50mm El Nikkor f2.8 NikonUser, the old version and the newer f2.8N version. I presume the "N" stands for "New". I think Craig's is the old original version?

This is the "N" version which is I presume mgoodm3's and yours:-

I seem to recall Charles Krebs said the "N" version was the better one?

Thanks Dave. I had assumed the newer 'N" version had an "N" mark somewhere on the lens housing; my lens has no such marking (perhaps it was just on the box, which I do not have).

Actually the one I posted was a 75mm. I also have an older style 50/2.8
