Is the ttartisan 10mm f 2 asph worth buying used?

I'd say yes, it's a good candidate for buying used. The used market is one of the best ways to save on good gear, and this is a manual-focus prime with no stabilisation, so there's little electronics to wear out. Check the glass for fungus, scratches, and haze, and make sure the aperture ring and focus ring move smoothly. I can't tell you what it costs used, so compare current listings before you buy.

It's built for APS-C, so it frames like 15mm on Sony E, Fujifilm X, or Nikon Z bodies. Good matches from the catalogue include the Fujifilm X-T30 II, the Sony a6400, and the Nikon Z50. For general advice on buying a secondhand body, see buying used.
