I would love to see a side by side of the Nokton next to the Panasonic 24mm f1.4. 1/2 the price and you get the benefits of an electronic connection. Unlikely, but anyone out there own both?
Besides the Nokton being 1.12 stops faster, the build quality, macro focusing distance, stepless aperture, and long focus throw are more than worth the price difference. Optically, I can't say which one's better at a give aperture.
NOKTOR hands down. My work horse. A normal lens on the AF or GH. Mine's not stepless either. Half stop steps. Great for low-light night shots, no talent roasting ever required.
+1 on Noktor. LOVES that lens! I shot at f5.6 all day with that lens today and everything locked in so nicely. Yeah, it's got beautiful bokeh too, for sure but it performs beautifully all around
