Re: FM Review: Voigtlander 90mm f/2.8 APO-Skopar | |
I doubt you'd be able to pick a difference in a blind test with the center, but the midframe and corner show exactly the sort of microcontrast loss you'd expect with significant distortion correction; and in the case of the corner, there is some loss of resolution visible as well.
Relatively coarse/ low frequency structures look similar, but its the fine fractal nature of the vegetation that takes a hit - as well, there's a sort of haze over the image that degrades the impression of 3D, so more of an issue for landscape photography.
Overall, the Sigma does well though, and I'd probably chose it over the new Cosina for landscape. Begs the question: what was Cosina up to here? It should of been relatively easy to produce a razor sharp lens acros the frame: the fact that its not, well, that must be on purpose, and provide some, as yet, undiscovered quality in the rendering.
