I'm worried it might by too stiff. I would be using it on a Yashicamat.
I'm also thinking of getting one made by Hama. Its the only one available locally. Though im worried that the little metal part, that pokes out as you press down the button, is too short for the Yashica. Does anyone have the Hama one?
I have the adapter. My current long cable release is unusable with it though, because the metal part that pokes out is too short (10mm). I have another cable release which works with it, but is only 15cm long and has no lock. Therefore I needed a new one. Should be here in a week or two.
