Lenstip has a review of the Voigtlander 42.5mm f/.95 out now. It's competitive with the Panasonic, but not quite as sharp for the most part. The Panasonic has incredible peak corner resolution, but the Voigtlander's corners sharpen up sooner, even if they plateau a little too much. Here: http://www.lenstip.com/395.1-Lens_review-Voigtlander_Nokton_42.5_mm_f_0.95_Introduction.html Voigtlander Resolution PL43 Resolution: On the other hand, the Voigtlander does far better with longitudinal CA: Voigtlander PL43 ...but worse on lateral CA: Voigtlander PL43 And worse Coma than the PL43 Voigtlander PL43 The Voigtlander has better Vignetting though, especially at f/1.4 Voigtlander PL43 I think the lenstip summary is a good one: Anyway...it's an interesting comparison. Certainly something to think about.
