Is the voigtl nder septon 40mm f 2 aspherical worth buying used?

Yes, I think it's a good candidate for buying used. This is a manual-focus prime, so there's no autofocus to wear out or lose, and an older copy gives you the same 40mm, f/2 view. The used market is one of the best ways to afford good gear, and a simple lens like this suits it well.

It's a full frame lens that fits Sony E and Nikon Z mounts. On a full frame body it frames as 40mm, and on APS-C it frames like 60mm. It isn't stabilised, so you'll rely on your camera's own stabilisation if it has any. Before you pay, check the focus ring for smoothness and the glass for scratches or haze, since you can't test autofocus to find problems. You can see the full specs and compatible bodies on the lens page.
