Canon New FD100mm f/2.8 is listed for Canon FD / New FD with image coverage not yet established in this record. A front screw-in filter size is not established by the checked evidence, so no diameter is recommended. The supplied research links this exact mount variant to manufacturer evidence. Body-specific AF, crop and adapter behavior remain separate checks.

Search camera lenses on AmazonChoosing a camera
Look for the Canon FD / New FD designation on the camera specification, then verify the exact model code and mount variant against its support page. The maker lists a 100 mm focal range and f/2.8 maximum aperture. A physical mount match is a starting point; still AF, movie AF, crop behavior, stabilization and firmware need separate checks.
Choosing a filter
A circular screw-in filter with a matching documented thread size is only a mechanical candidate. Magnetic filters, wide frames and stacked rings need separate system and vignetting checks. When no front thread is specified, do not buy a size from the focal length or barrel diameter.
This model cannot enter the diameter calculator until a verified front thread or dedicated holder specification is available.
