Summary
Pros:
solid, very well-made and compact barrel at the same time,
very good f/0.95 aperture,
sensational image quality in the frame centre,
good image resolution on the edge of the frame,
chromatic aberration controlled in an excellent way,
decent correction of astigmatism,
not very bothersome distortion.
Cons:
the image is distinctly „fuzzy†at the maximum relative aperture,
significant vignetting near the maximum relative aperture,
high coma.
The flaws of the Nokton 0.95/25 are quite typical for very fast lenses with the field of view on the level of 40-50 degrees. In fact almost every single one of them features huge vignetting, high coma and an average image quality at the maximum relative aperture. Splendid fastness, compact dimensions, perfect build quality and exemplary image quality on slight stopping down are the chief assets of the Voigtlander, tested here. Such advantages are certainly not common in the case of classic 50 mm lenses so the users of the Micro 4/3 system gain here a very strong point.

The users of a mirco 4/3rds system do NOT gain a "very strong point" here.... They merely gain an interesting lens ONLY for the 4/3rds camera they own.
Lets do the math:
25mm x 2 crop factor = 50mm
f0.95 x 2 crop factor = f1.9
So.... basically a 50mm f1.8 equivalent. Want to compare prices? Even 50mm f1.4 lenses are most of the times more affordable.
That is for full frame.
What about APS-C?
Canon 35mm f2 (full frame + APS-C)
Canon 35mm f1.4 L USM (full frame + APS-C)
Nikon 35mm f1.8 DX (APS-C)
Sony 35mm f1.8 (APS-C)
Sigma 30mm f1.4 EX DC HSM (APS-C)
Tokina 35mm f2.8 1:1 macro (APS-C)
It was only 4/3rds which did not offer any "standard" lens with such an aperture. Now they finally have one option, without AF though.
