I recently acquired the Komura 28mm f3.5 for what I now think is a very good price after shooting it (from a very reputable London Leica dealer).
Anyway, I can't for the life of me figure out how to detach the lens hood to mount a 55mm filter. I can see the filter thread, but can't figure out how the hood comes off (without excessive twisting).
Any ideas?

Should simply screw off. I had a 28mm Komura at one time and had a 55mm Komura hood attached, which was an SLR hood and the brand name did not line up correctly on the lens, but it worked fine. Simple screw-in hood.
Maybe it's been on there a long time and froze in its threads... Good luck.

Ahh, thanks. I was hoping there was a secret little switch rather than fear-inducing twisting. Will give it another go.

Yep. It's a screw top ;-)

Drip a few drops of 97% alcohol into the groove between hood and thread and let it sit for half an hour. Also, before trying to unscrew again, carefully but firmly tap the hood all around the front edge while setting it with the rear cap onto a firm surface.
The alcohol might dissolve anything chemical that's in there and bonds the parts, the tapping might loosen any oxidation between the thread and the (probably) aluminium lens hood.
Let us know what did the trick!?

Sorry, forgot to follow up...
Magically, it twisted off just fine when I tried again, not much friction. The only issue now is that the hood obviously isn't designed to work with a filter (images show a lot of vignetting if its on with a filter).
Thanks guys.
