the reviews on this are wildly mixed.

Architect1776 Loc: In my mind

A lot of worthless links posted here, they are for Nikon lens to Canon body.
I believe there are no adapters for Canon EF mount lenses to Nikon body cameras. I would guess that there might be some obscure place that could custom make one though. The Nikon body is too thick as you know and infinity is impossible unless some optic were placed in the adapter. That is generally a last resort though and there does not appear to be a market for that. The other way around is much easier as the Canon body is much thinner and allows many lenses from other manufacturers to be mounted and focus to infinity including Nikon with no optics needed to go to infinity.
So your only option that I know of is to get a FF Canon body and then lose the flash you have which seems to not be one either. Just one of those things that don't work which is too bad. Perhaps if Nikon makes a FF mirrorless someday it will be thinner and then you will be able to use the EF lenses on it and adapters will become readily available. Not sure if or when that will happen though and if they will make it any thinner or keep the old mount.

If I remember correctly Nikon made extension tubes and I think they made a tube with a helicoild so you could adjust the extension getting you to about 3x if not they have bellows that will do just that and still be able to use your flashes however the best I ever saw was a enlarger lens set up with a 105mm Nikkor enlarging lens which you could also use reversed, Nikon used to make a BR 2 reversing ring for their 55mm macro lens which might also work for you. Macro photography is very specialized and very special equipment. Good luck in your journey.

I have long wanted to do that also. I don’t wish to buy a Canon body just for the purpose as then I would also have buy flash etc. One possibility I was looking into: B&H sells a male Nikon lens flange. Get that and a female Canon lens flange and have a machinist make a short connecting tube. I have a home machine shop so I could do that myself. You would, of course, lose all interconnectivity but that shouldn’t be a significant problem. Another option is to get lens reversing rings and mount it backwards. Again, all manual. While I was trying to decide if I wished to do that Venus announced a Laowa 25 mm f2.8 2.5-5x Ultra Macro for $399. The aperture is manual but otherwise it connects. It will not be available until the end of May. Google it, some early reviews were very impressive, in some ways better than the Canon. I have it on pre-order at B&H.

Good idea DaveC, to machine an adapter. I also have a home machine shop so can do. BUT there is the nagging issue of no aperture control. That is the stickler. The best idea I have tried so far is to get a used 25-50mm F4 AIs zoom lens and reverse it with a BR-2a ring and a 72 to 52mm step-down ring. Use a BR-6 adapter on the zoom lens mount flange surface allows the use of a double cable release to allow you to focus wide open, then depress the twin cable release button to first stop down then expose the image. And the BR-6 provides some protection to the zoom lens exposed optics which are close to the surface. I get from about 1X to 3X with that rig. Let me know how that Laowa lens works out for you.

If it's only the 5X you want I can do that with my Nikon PB-6 and my EL-Nikkor 50mm.
Second thought, may be not. I get very high magnification with the setup but may be not 5x.

I have that bellows, and that same enlarger lens. But a bellows is awkward in the field, as well as delicate? Maybe I am enthused with the possibilities of that Canon MP-E 64mm lens? A lot of macro in one package. Though the critics have said 4X is great, 5X not so much. Basically the Canon lens is a reversed zoom lens with optics optimized for one use: macro.

That Fotodiox adapter won't work. That's a Canon FD to Nikon F adapter. It's the wrong Canon mount.

The MP-E 65mm is a Canon EF mount lens. Whole different animal! Larger diameter bayonet mount, shorter lens register... but the real kicker is electronic aperture control. Both Canon and Nikon use it now (all Nikkor "G" for example)... But I've never heard of anyone ever working out a way to get the different electronic control systems to talk to each other.

I honestly do not think there is any way to use an MP-E on a Nikon body. Even if you get it to fit somehow, I doubt the electronics could ever be adapted.

You'd have better luck just getting a Canon camera to use the lens on... and a flash. In fact, as high magnification as you'll be doing, you are probably not going to be using a standard flash.

I use the Canon MR14EX Macro Ring Lite on my MP-E 65mm.... that ring light is designed to clip directly onto the front of the lens... and the lens is designed to accommodate it. In fact, the MP-E 65mm is the only lens I use a ring light with. I don't care for the effect of ring lights on lower magnifications. But it's ideal for the MP-E 65mm at 2X and greater. Current version of the MR14EX is an RT/radio controlled model that can work in conjunction with other RT flashes. I use the older version and see no need to upgrade, because I don't ever use the ring light in conjunction with other flash. (I know for certain that Yongnuo also makes a Canon ETTL compatible ring light. Others probably do, too.)

It's a topic for another thread, but I really never understood all the buzz about Nikon flash anyway.... or the disdain for Canon flash. I've been using Canon EX-series flash for years. They work great and are easy to use. My only gripe with them was that their off-camera control was via IR light, which limited placement and distance considerably. But the same was true of Nikon flash. Until, beginning around five years ago, Canon intro'd flash with much better radio control and triggering in all the RT-series flashes, plus there are now third party products that can adapt the older optically triggered flashes to the same radio control, too. Problem solved. (A couple years later Nikon followed and intro'd radio control flash, too. SB5000 I think was first, and a couple others since.)

Wouldn't be the first time someone bought a camera and accessories from a different system, just to use a particular lens. In fact, when Nikon introduced their 35mm PC lens back in the 1970s, a lot of Nikon users ended up carrying around a Konica SLR, too. It turned out that the Nikon bodies of the day could only meter that PC lens when all it's movements were reset to 0. That was a pain in the arse. Then someone discovered that the lens could be metered at any of it's settings on a Konica. body.... and that there was a widely available Nikon F to Konica K/AR. So a lot of Nikon shooters who using that special lens ended up with a T3 or similar in their camera bag, too. Demand for it drove up the price for it and to this day, the Nikon F to Konica K/AR adapter still sells for about 3X as much as other, very similar adapters that allow various other mounts be used on Konica.

If you would feel "unclean" buying a Canon camera, how about a Sony? There are adapters that allow Canon EF lenses to be used on Sony... even controlling the aperture (pricey, though.... around $400 for some of the adapters... and I don't know for certain an MP-E 65mm would work, but I also can't imagine why it wouldn't). The Sony cameras that can use EF lenses via an adapter are their mirrorless models, which are available in both APS-C and full frame formats. AFAIK, they all use electronic viewfinders, too... which would be a nice feature for some high magnification macro work. I don't know anything about the Sony flash system or if it's possible to use other system flashes with it.

Another possibility... Venus Optics Laowa is introducing a macro lens with 2.5X to 5X range of magnification that will be available in Nikon F-mount. I don't know much about it. Not in stores yet, AFAIK. Probably manual focus AND manual aperture control (as have been some of their other lenses).

Yet another possibility... get a macro bellows for your Nikon and an appropriate Nikkor to use on it. After all, the MP-E 65mm was essentially designed to serve as a replacement for bellows (which are problematic on the system's electronic mount). There are any number of bellows available for Nikon... their own and many other brands... and with the right lens they can be capable of just as high magnification.

Not sure where you heard that myth, but G lens diaphragms can be actuated mechanically.

Architect1776 Loc: In my mind

That is only for FD, has an optic in it.
The lens in question is the EF mount which is completely different and not related to the FD/FL/R mount.
