    I got this new TLR, it's a Seagull GC-104. There's no thread size printed inside the lens cap like usual, so I looked in the manual, and the english-translated part says this:

    "Can be provided with a lens hood and filter. The connector sizes of them are as follows: M34x0.5 thread type, or ø 36mm slip on type."

    Can anyone make sense of that? I want to get a step-up ring so I can use my "screw-on" filters with this. Since I don't think(?) it would be called the "slip on type," I assume the important number here is M34x0.5, which I have never seen before.

    Would this be 34mm do you think?

    Thanks!

    After some (rather unsuccessful) Googling, might this mean 34mm with a thread pitch of 0.5mm?

    I think it's 34mm, though I've never had a Seagull- my TLR of choice was the Mamiya C330, which had interchangeable lenses :)

    Thanks! Do you know if this "M" notation has a name or anything? I don't even know what to Google for.
