A small case is included to safely store and transport the adapter.

A way to use old lenses

By Richard
Rated 5 out of 5
Date: 2025-08-19

I've been using Nikon cameras for more than 40 years. The lenses that I used with my old (film) Nikkormat EL are still good, but difficult to use with the new DLSRs. Ths adapter connects to any lens with a F-mount and allows you to use it as a telescope. Breathes new life into some very expensive relics.

Great way to use old glass

Have a stash of Minolta MD lenses I haven't touched in years. Got a thin Fotodiox MD-to-F adapter along with this Lens2scope item. Now my old lenses work very well as spotting scopes for field and boat use. These cascaded adapters modify and soften the focus point a bit, but I've been able to manage it through manual adjustment.

Is this good for target shooting spotting scope 50ft to 100 yards? Which lens mm works?
Asked by: Earnest
Yes, the Kenko Lens2scope Adapter for Nikon F Mount (Angled View), is good to create a target shooting spotting scope. the 200-500mm Nikon lens would be one of the best for 100 ft., or a 70-300mm one for 50 ft. https://bhpho.to/3VPMwHw https://bhpho.to/3VPMMX0

I assume this will work fine for I assume this can be used, with good effect, as a spotting scope at a shooting range to see where I hit while aiming. Any thoughts?

Will this fit a Nikon 6z mirrorless camera to capture photos from the spotting scope?

The Kenko Lens2scope Adapter for Nikon F Mount (Angled View), B&H # KELNFA, converts any Nikon F-mount lens into a spotting scope—it will not accommodate a camera body to capture photos.

question

Overview states it turns a 100mm lens into a 1000mm spotting scope. Shouldn't it turn a 100mm lens into a 10mm spotting scope?
Asked by: William D.
You need to divide the focal length of the lens by the focal length of the eye piece.100mm lens divided by 10mm eye piece = 10 mm spotting scope.600mm lens divided by 10 = 60 mm If yo add a 2X converter to the lens it would double the spotting scope magnification
