"sawed off" Jupiter 12? Possible to make it shorter?

[paniolo]

Hello Photographers,
you all know the "famous" Jupiter 12 35mm 2.8 lens in LTM mount. Wouldn't be nice to make it shorter somehow to let it not block the bottom corner of the viewfinder anymore?

Any chance to do this without harming the mechanics?
I imagine just to cut off the "sunshade" and shorten the aperture controle.

Regards
Paniolo

Are you using it on a Barnack, or on an M? If a Barnack, I guess you are already using an accessory finder. If it blocks the M finder, maybe the simplest thing would be to use an accessory finder there as well?

Cheap stuff. Just cut the corner off and see what happens.

OP, I googled it for you in Russian.
Construction of J-12.

The answer is, no.
Do not vandalize. Russian will come and shave your head off, Pherdinand is next in the list. 😎

nananana, i dont like external viewfinders.
I just want to use that on my M2.

Would it be safe to cut along here?

Would that put enough out of the way from view so that it is worth doing this?

It still looks as though you'll be interfering with the mechanics. Honestly it sounds like a terrible idea and if the view annoys you that much then buy a different lens. If you're really in love with the optics then you could have the lens block remounted into an alternative barrel, but doing that is expensive.

You are right. I will better use it how it is.

Chicken.

Just put it to the belt sander. What could go wrong 😉
