Hood recommendation for M 20/4?

Any hood recommendation for the M 20/4 that will not vignette on a full frame? It has a 49mm filter thread. I can't find an original hood.

I'd be happy with anything not too expensive, e.g. a rubber hood.

Thanks in advance

I do not think such a hood excists. I have one, and even a UV-filter is tricky, you need a thin one, otherwise there will be vignetting

It definitely exists - just not enough to go around.

Thanks guys. I had a look at those hoods - wouldn't they vignette at 20mm? I would thought that's why the original square hood is so narrow?

Use a step-up ring to 52mm or 58mm,
then a hood to fit that diameter.

It's what I did for the M20/4 on an LX.
I already had the big dinner plate hood from an old Takumar 20/4.5,
58mm filter thread, so just converted to that.

In baseball terminology,
it's called "stepping up to the plate".
