7artisans 18mm f 5 6 vs voigtl nder super wide heliar 15mm f 4 5 aspherical iii?

Both are manual-focus primes for full-frame bodies, so the choice mostly comes down to how wide you want to go.

The Voigtländer Super Wide-Heliar 15mm f/4.5 is the wider of the two and the one I'd pick for interiors, big landscapes and dramatic perspective. It also covers Leica M, which the 7Artisans doesn't.

The 7Artisans 18mm f/5.6 is a gentler wide angle. It mounts on L-Mount as well as Sony E and Nikon Z, so it's the one for Panasonic, Leica SL or Sigma bodies. Its slower f/5.6 gives you less light and less background blur than the 15mm's f/4.5.

If you're unsure, start with the 15mm for its wider view. If you shoot L-Mount, the 18mm is your only option here.
