An he is correct, it does indeed work using a canon body and lens, I have done it many time before I got my macro lens. Though I prefer to use a Reverse Mount lens converter that I posted a picture of in another post earlier.

Cool!

These adapters that have the electronics, have been available for Canon dSLR's for a long long time. I bought mine almost 12 years ago now.They will work with any of the Canon EF or EF/S lens. I have never tried them on a lens made by any other camera lens maker. I am sure if the lens is made to mount to a canon dSLR it will work just as well. I do not know if such a adapter for Nikon or not.

Novoflex offers adapters like this, but they cost a lot more than $60. They offer Canon, Nikon and Sony. I didn't look for any other cameras.

Just Google "Novoflex reverse adapter canon" or nikon or sony to see them. Maybe someone else makes these. I didn't search for any of them.

When reversing a lens, there is a limited range of focal lengths that this will work. Highest magnification comes from shorter focal lengths. The following FL's work: 28mm, 35mm and 50mm. As you move to longer FL's, they will not obtain focus as the focal plane moves into the lens.

Manual macro lenses can be cheap enough that you can bypass reversing lens altogether. In the case of macro lenses, the longer the FL, the longer the working distance. I have several manual macro lenses in different focal lengths, and they really do work well.

Yeah, I have seen the prices that Novoflex is asking for their stuff. It put it out of the range most people beginning in Macro would spend. I have long past using reverse lens. Not that they didn't work, I have just purchased true macro lens along my journey, like the 60mm, 90mm, 100mm and the IRIX 150mm. I have even been using microscope objectives in the 5X and 10X range. I believe that using reverse lens and things like extension tubes are a great way to dabble in Macro photography without breaking the bank, when starting out.

First I've seen one. Great solution.

If you were using a Canon you would set your aperture to f/11 and then press the DOF button, and while holding the DOF button your would remove the lens, and then turn off the camera. The lens now will be set to f11 and can be reversed mounted. If you want a different aperture you would have to go throuh that whole process again while choosing a different aperture size.

Ahhhh, no.
Luckily I have an old 50mm FD on a camera in the curio cabinet. Some day I'll try playing with that.
(Not urgent as my Sony H-1 focuses down to 2cm.)

Same as film camera , 100 % manual function , get descent results after some practice . An old 50mm lens work best .

Okay. I am educated on using a reversing ring with an electronic lens, but my question is why one would use this Rube Goldberg setup over a dedicated macro lens. Do you get the same flat field and corner to corner sharpness that are typical of dedicated macro lenses?

If you wanna fuss around, you could set an aperture with the lens mounted normally and then remove the lens BEFORE powering off. Now you have a fixed aperture lens, f/stop as you chose it. Now you can reverse mount it. This works on most cameras but its really more trouble than its worth.

For me, reversing any lens has always been more trouble than what it's worth !

It's CHEAP and challenging .......that is the attraction

On the old Canon FD lenses one could lock the aperture and manually adjust it.
I've no idea how one would do that with the current lenses for digital cameras.

Stuck wide open in that case?

The ones I have tried stick at smallest aperature which is likely what you wanted anyway.

Hopefully you, unlike everyone else, have not yet lost the stoopid little black plastic doodad Canon generously supplied with your FD lens.

Acoarst, I dont remember how to use it cuz I always threw it away. Maybe youve kept the box, and all contents, for the past 50 years ? If so then the instructions are also in the box.

Period.

Years ago (50?) I used to use a ring to reverse my lens on the camera for macro. Going through some boxes in the closet I came across a couple. How different would it be using these rings on a DSLR

I used to do the same thing, back in my film days, when I couldn't afford a macro lens.

In fact, one of the last photos that I took using a reversing ring was almost 50-years ago (48 to be exact) as seen below.

Shortly after this, while I still couldn't afford a macro lens, I opted for a cheaper solution, a set of extension tubes. This was superior to reversing the lens since the extension tubes connected the lens' aperture controls to the camera so that you could use the automatic thru the lens exposure system. The set came in three sizes, 14, 21 and 28mm. They could be used individually or in pairs or even all three, to get maximum magnification.

Today, with my Sony a6500 mirrorless camera, I can now afford a dedicated macro lens, in this case, an Artisans f2.8 60mm Macro lens. That being said, I also have a set of extension tubes for my E-mount lens, only this set consists of two tubes, a 10 and a 16mm, which again, can be used individually or together. And again, they allow the full automatic functioning of your lens, including aperture as well as focus.

Now here's that nearly 48-year old picture:
