What is it's purpose?
I ordered a used 28+90 adapter, and of course it arrived without the wrench. I'm not sure I need it, but figured I'd inquire about it's purpose.
PS: I haven't installed or otherwise used it yet.

Isn't the rear cap that comes with the adapter also a "wrench"-- there are teeth on the back side that can aid in removing an adapter from a camera body when no lens is attached.
I don't think the wrech is needed-- just carefully thread the adapter onto your lens, and then attach to camera body. Tighten appropiately by hand.

Some brands of adapter do come with a "skate key" metal wrench. It has two pins that fit into recesses in the front (lens) face of the adapter.
I can only assume the skate key is for the convenience of people who like to take ONE adapter and install it in an M-mount body, then screw different LTM lenses in and out of the adapter. Having the skate key would it easier to remove the adapter from the camera body, which otherwise would be difficult because of the lack of a gripping surface.
Seems bats to me -- I'd rather have an adapter for each lens, so I can change them more quickly -- but I guess there are people who do it.

Ah I see...

The skate key would definitely make removing the adapter easier i'd guess.
With that being the case, and not owning a skate key, it looks like I could use one of the wrenches purchased from MicroTools--the type used to take retaining rings off lenses when stripping them down. Yes?

Adapters can easily be removed by mounting the lens in the body, and unscrewing by hand without pressing the release button on the body.
I've never seen a need for a key or wrench.

Right...but what about when you want to remove the adapter from the body?dpetrzelka said:

As dptrzldkcvptrazptrkla noted, usually you can use a lens as a wrench. Just screw the lens into the adapter fairly firmly, then press the bayonet release on the camera body and twist. Unless the body's bayonet mount is really, really stiff, the adapter will usually un-bayonet from the body before the lens unscrews from the adapter.
Once the adapter has twisted to the fully released position, it will stop there. Then, if you want to remove the lens from the adapter, you can go ahead and unscrew it. In the released position, the adapter will lift easily out of the body's bayonet mount.
Times when the skate key comes in handy: (1) When you need to get the adapter out of the body (perhaps to mount an M-mount lens) and don't have a screw-mount lens handy; (2) if the bayonet mount in your camera is really tight, so tight that the lens unscrews from the adapter rather than turning the adapter to the unlocked position.
Tip: If you only need to do this occasionally (or once) and don't want to buy a pin wrench just for that purpose, get some rubber tape from a hardware store and put two small strips on opposite faces of the adapter. Then press the bayonet release button with a finger while twisting the adapter with your thumbs. The super-friction of the tape gives you a strong grip that will usually be enough to twist the adapter.
Incidentally, rubber tape is useful for a lot of other camera and household chores, such as unscrewing front lens rings, wind-lever hub rings, stubborn jar lids, etc. This is not thin vinyl electrical tape -- it is made of flexible, rather tacky rubber, about 1/16 inch thick, and has a peel-off liner on one surface to keep the tape from sticking to itself.
Its intended purpose is to insulate and waterproof electrical connections -- it's so "gooey" that it fuses to itself as you wrap the splice (so it's sometimes called "self-fusing tape.") But this same gooey, tacky property makes it very handy for any time when you need to create a cushioned, high-friction gripping surface to help you unscrew stuck parts by hand.

The Voigtlander brand of adapter ring comes with a rear lenscap that has a raised key that matches a notch in the ring. The cap functions as a key. I didn't know this until I read the instruction sheet that came with the ring.

Dancing in the grain
I bought an Nokton 1.5 50mm with a wrong (35mm) Voigtlaender Type I adapter mounted. I've been trying to make it come off the lens for most of the morning today, but the thing just doesn't want to move.
Is there some comprehensible how-to that would explain what to do? i tried mounting a rear lens cap on it and removing it by turning the lens cap while holding the lens by the back part of it....
I'm afraid to damage the lens and/or the adapter, as I don't know if I'm turning it in the right direction (that is counterclockwise with the rear lens cap facing me).
I don't want to use the body as a wrench as I don't want to damage the camera.
Can someone share suggestions how to unscrew the adapter? I don't know for how long it's been on the lens.
