Is the voigtl nder nokton 75mm f 1 5 aspherical worth buying used?
The Nokton 75mm f/1.5 is a manual-focus prime, so it suits photographers who don't mind focusing by hand. It's full frame at 75mm, and on APS-C it frames like about 112mm (Sony E or Nikon Z) or 120mm (Canon RF). It fits a long list of bodies, including the Sony a7 III, Nikon Z6 II and Canon EOS R6.
I don't have used prices for this lens on the site, so I can't say whether a given price is a bargain. The general case for buying used still holds: a body or lens one or two generations old often gives most of the value for much less. Check the condition carefully, and budget for a new genuine battery with any used body.
