macro question
May 9, 2019 09:11:12 #
Hi everyone,
This is my first time posting a question I love reading this forum..anyways.
I have an El 2.8 50mm lens, this was for enlarging back in the film days..I noticed some posts showing awesome macro shots when lens is reversed with a tube.
Question: What size tube and What adapter should I use for nikon d7100 or d5100 or d700?
any ideas or comments from someone doing this would be welcome.
Thanks . 🙂

A reversing ring is what’s used to reverse a lens, not a "tube". If by tube you mean extension tubes, I don’t know if these are designed to work on a reversed prime. They’re designed to connect to the camera body and then to a lens.

Check out the links on the first page of the True Macro Forum:

The discontinued Nikon BR-15 ring will adapt your lens. If you cannot find one used, this will work as well:

If you have specific questions, just ask. Close-up and macro photography is fascinating, enjoy!

not sure of correct name for "tubes$ ky understanding is that different lengths will have an effect on magnification.

Your understanding is correct. You can add extension tubes to increase magnification, whether the lens is reversed or not. I don’t think you’ll gain anything by reversing your EL Nikkor. About anything you could want to know about the subject, including terminology, will be found in the True Macro section.
Edit: For more versatility with tubes, check the FotodioX Viselex Macro Helicoid tube.

I use my Nikkor EL lenses on the bellow. They work great.
I use one of this

and a Nikon PB-6 bellow.

Just a caveat ...
Many older enlarger lenses don't really adjust focus.
They are *made* for an enlarger- as in, you move the camera to adjust the physical distance.

And thus I use it on the bellow which provides focus but generally only for close up. My 135mm EL Nikkor on the bellow can focus to infinity. The 105mm can focus to about 30ft. I also use the 80mm and 50mm but those only for very short distance.

When reversing a lens you use a step up or step down ring. This fastens on the end of the lens using the 'filter' thread.
Extension tubes generally come in sets of three sizes which gives a variety of lengths. (Interchangeable) some of the cheap plastic ones can be used in full manual only as they do not contain any electronics. To use, you manually focus. OR the expensive extension tubes specific to your camera have electronic contacts. If you are using old lenses...they will not have electronic contacts to match your camera - so use manual focus...
Macro requires a lot of thought with lighting....you get so close that there is very little incidental light. Look at small 'daylight' led torches or anglepoise lights so that you can direct the light.
I have used cheap extension rings - they work! however, you sometimes have to manually open the lens shutter when you screw the 'end tube' on. there is a spring loaded pin on the lens and a tiny lever (which may need a little gentle prodding) on the tube. make sure that this engages as you screw then together. There is one on every ring, but the 'end' one is the only one to worry about. the threads are very delicate so rub a little petroleum jelly (vaseline) on them and 'be gentle'. AND wash your hands before handling lens!
Have fun

This site should help to describe the process and kit needed to undertake what you are trying to achieve with the enlarger leans (microscope objectives can be used too) - see here: http://extreme-macro.co.uk/componon-28mm/
