Will old ae1 lenses fit canon dslr?

Old AE-1 lenses, which typically use the Canon FD mount, are not directly compatible with modern Canon DSLRs that use the EF or EF-S mounts. However, there are adapters available that can allow you to use FD lenses on Canon DSLRs, but these may result in manual focus and exposure adjustments. It's important to note that using such adapters may limit certain functionalities of the camera. Always check compatibility and functionality before purchasing an adapter.
