AI Lens mount (Letus)

[Shooter]

Does a Non AI Nikon Lens, mount to a Letus AI Adapter (or is it no go at all.) ?

[Charles Lowthian]

If it's the standard bayonet (nikon) mount, should be fine as there is enough space in the adapter between the mount and the glass to allow for any 'extra room' needed on older nikon lenses.
