What to expect#
Aperture control: lenses with a manual aperture ring work directly; electronically controlled lenses (no ring) need a smart adapter or one with a built-in aperture lever.
Focus: use focus peaking and magnification in the viewfinder. Exposure metering works normally because the camera meters through the lens at working aperture.
Crop factor: on a 2.7× crop Nikon 1 (CX) body a 50 mm Sigma SA lens frames like 135 mm. A focal reducer (“speed booster”) can bring back some width and gain about a stop of light.

Frequently asked questions#
Will Sigma SA lenses autofocus on Nikon 1 (CX)?
No — adapted lenses are manual focus on this combination.
Does a Sigma SA to Nikon 1 (CX) adapter affect image quality?
A glass-free adapter is just a precisely machined spacer, so image quality is unchanged when it is built to the right thickness. Cheap adapters can be slightly too thin or thick, which shifts the infinity mark.
