What filter size does the leica summarit m 50mm f 2 4 take?

I don't have filter size for the Leica Summarit-M 50mm f/2.4 on this site, so I can't give you a thread size without guessing. The lens page covers what I do know: it's a manual-focus, non-stabilised prime for full frame, and it fits the Leica M mount. You can check Leica Summarit-M 50mm f/2.4 for the rest of its details.

For the actual thread size, your best bet is the lens body itself, where the size is usually engraved, or Leica's own documentation. If you're buying filters, check the size before you order. If you tell me what you plan to shoot, I can point you to the right kit on the landscape page, which covers filters like the circular polariser.
