SVBONY SV149 Nikon AF Lens to 1.25″ Camera & Eyepiece Adapter

Product Overview

The SVBONY SV149 is a mechanical adapter that puts a Nikon AF (F-mount) camera lens in front of a 1.25″ eyepiece or 1.25″-nosepiece astronomy camera. One side takes the Nikon bayonet; the other is a 1.25″ holder with a brass ring that grips the barrel. The CNC-machined aluminium body uses an M52 x 0.75 adapter thread, measures 78 x 58 x 60 mm and weighs 137 g.

Who It's For

This is a good match if you own Nikon AF lenses and want to use one as a short-focal-length imaging optic for an astronomy camera, for wide-field Milky Way, constellation and large-nebula framing, or as a simple lens-plus-eyepiece viewer.

Key Features & Design

• Nikon AF bayonet: accepts most Nikon F-mount DSLR lenses.
• 1.25″ holder with brass ring: holds an eyepiece or camera nosepiece securely without scratching the barrel and keeps it from slipping out.
• M52 x 0.75 adapter thread.
• CNC-machined aluminium alloy: all-metal construction, black finish.

Recommended Uses

• Wide-field astrophotography with a Nikon lens and a 1.25″ astronomy camera.
• Lens-based guiding or finder setups using a camera lens as the optic.
• Visual use of a camera lens with a 1.25″ eyepiece.

Compatibility and Accessory Notes

• Lens side: Nikon AF-Mount (F-mount) lenses.
• Output: any 1.25″ eyepiece or 1.25″ camera nosepiece.
• Mechanical only: there are no electronic contacts between lens and camera.
• Canon version: SVBONY also makes the SV149 for Canon EF/EF-S lenses as a separate model.

If you are pairing a particular lens and camera and want to confirm the fit, send us both and we will check it with you.

Good to Know Before You Order

• No electronic control: it is a mechanical adapter, so autofocus and electronic aperture control are not available.
• Lens and camera sold separately.
• Bundle style: SVBONY also lists an SV149-SV405CC camera bundle; this listing is the adapter on its own.

Frequently Asked Questions

Does it work with Canon lenses?

Bottom Line

In short: a 137 g all-metal adapter that turns a Nikon AF lens into a wide-field optic for a 1.25″ astronomy camera or eyepiece.
