Works as advertised. Fits my hasselblad 80mm lens perfectly.

Junk

This adapter is junk. It doesn’t fit securely on my stock Hasselblad 80mm. Without modification, this product and the filter you attached can fall right off the lens

See any errors on this page?

question

Is this compatible with a Canon EF50mm f/1.8 STM lens? I have 58mm filters.
Asked by: Mary M.
No. Zeiss/Hasselblad only.
