9 lens mounts × 5 camera mounts
Every film-era SLR mount we cover sits farther from the film than any mirrorless mount sits from its sensor. That gap is what makes adapting work: a hollow ring makes up the difference and the lens focuses just as it did on film. Pick your lens mount and your camera to see the adapter depth, the settings to change and what each lens becomes.
