Is the laowa argus 45mm f 0 95 ff worth buying used?
I can't tell you what a used Laowa Argus 45mm should cost, because the site doesn't list prices. It's a manual-focus prime with no stabilisation, so it suits people who enjoy focusing by hand. Its fast aperture is the main reason to own it, and that's where a used copy makes sense. The buying used guide makes the case that good gear is one of the easiest things to buy second-hand.
It mounts on Sony E, Nikon Z and Canon RF, and the lens page lists every full-frame and APS-C body it fits. Compare any used price with new before you buy, and make sure you actually like manual focus. If you're still choosing your first body, your first camera is a good place to start.
