multiple adapter on one lens, will it work?

i have some m42 and exakta mount lens. currently i own a canon eos body. so i have m42 and exakta to canon adapter. but i want to buy a fuji mirorrless camera.

my question is, can i just stick those lens into their canon adapter and then stick it that into canon-fuji adapter? so that i just have to buy canon-fuji adapter to use my canon and all of my vintage lenses

In theory, yes. In practice many of these combinations will work, but some won't. We've used stacked adapters like this many times with few problems.

However... we recently acquired a generic Nikon G to Fujifilm X adapter which fits our X-E1 camera perfectly. When trying to fit it onto a set of generic FX extension tubes, it won't mount.

I suspect that the slight variations in the dimensions of these independent products sometimes add up to make an incompatible combination. The only way to know for sure if two such adapters will fit and work together is to try them. For branded adapters a web search may find someone who's tried the combination before.

Hope this helps.

My lenses all have EF mounts, several brands vintage, several brands EF including 2 Canon lenses. The vintage ones got either an adapter (Olympus OM) or were converted to EF mount (FD, Minolta MD). I used them on my Canon 5DII but had a switch to an A7RII in mind. Made that switch and bought an MC-11 EF-FE adapter. Over time I put programmable AF confirmation chips on the EF mounts of the vintage lenses. The focal length of all lenses is now correctly transferred to the A7RII for IBIS and EXIF, not the maximum aperture. With some care the play between the camera body and lens with two adapters can be very little, with the converted mounts it was alright from the beginning. I did not like the slight rotational play with some lenses but that could be solved by exchanging small screws with slightly bigger head ones so the EF bayonet has less slack on the rotation. With the OM-EF adapters I solved it with some tiny drops of polyurethane glue that expands between the adapter plate and the lens plate. easy enough to remove that in the future but fixes them nicely. Main issue was the connection between the electronic connectors (chips and OEM EF) of the Sigma MC-11. The adapter is less forgiving/somewhat too tight, even to EF lenses. Changed the chips and one Tokina EF lens to get it right, they had no problem on the 5DII.

I was adapting to an EOS camera before I made a move to my NEX-7 and now A7r, so I had 3-5 EF adapters with EF caps for most mounts so I didn't have to swap the adapters, it worked quite well, I had originally planned to just get an EF to E adapter and continue as I had before, but it turned out to be a less an ideal setup, because with multiple adapters each has a tolerance and when they stack, the combined tolerance can drift closer or farther depending on the combination, and each time you add an adapter, there is an increased risk of light leaks, and also an increased risk of the lens not being parallel to the sensor, so I've mostly moved to a dedicated E mount adapter for each mount.

As others have mentioned, each (extra) adapter you use increases the chances of something going out of specification.

In practice, it can work, and rather well: I use a Techart Pro autofocusing adapter on my Sony A7RII, which has a Leica M mount on the lens side. I use M lenses with it, but also Contax, Leica R, Olympus OM, Rolleiflex QBM and Pentax K lenses, each type with its own adapter to M mount. I've carefully checked infinity calibration and flatness of field for each combination, shimming where necessary (2 of the adapters).

The results are excellent, but without the careful checking and adjusting, 2 of the 5 combinations would have yielded suboptimal results.

so i tried this configuration on my friend's sony A7s with canon adapter.

nikon-canon-sony
m42-canon-sony
exakta-canon-sony

all of them works fine, and focus correctly. so i think my fuji will work as fine as this sony.

thanks!

I've used M42, OM & PK to EOS adapters (&reversing rings) on several EOS-MFT adapters (normal, helicoid, focal reducing & tiltable models). No noticeable problems with any of these.

For normal photography it's unlikely that the alignment errors will have a significant effect, the lens might be slightly off center or tilted by ~0.001° but this would only show in careful test shots. (An individual element being decentered makes much more difference IIRC).

Issues become more noticeable if electronic comms are needed but all off mine are dumb adapters. Sometimes poorly made adapters can have excess freeplay which could easily become more of an issue as more connectors are stacked.
