Is the voigtl nder nokton vintage line 35mm f 1 5 aspherical worth it?
It depends on what you shoot and which camera you own. This is a manual-focus 35mm f/1.5 for full-frame Leica M bodies, with no autofocus and no stabilisation, so it suits people who already like working that way. The fast aperture is the reason to buy it. It's built for low light, people and food, which is what my lenses guide recommends a fast standard prime for.
If you shoot a Leica M, good pairings are the Leica M11, the Leica M10, or the Leica M (Typ 240). If you want to spend less, the Voigtländer Ultron 35mm f/2 is the same focal length on full frame, but it gives up a stop of light. I don't list prices on these pages, so check those before you decide.
