Sony NEX czy Olympus PEN?

[Piotr_0602]

Test dwóch szkiełek do NEXów.

Optycznie tak sobie (50mm) albo kiepsko (30mm).
Trochę powtarza się historia z naleśnikiem 16mm f/2.8 - trzeba przymknąć, brzegi mydlane, aberracja przeszkadza.
Ale jest też zaleta pięćdziesiątki - śliczny bookeh.

Świetna matryca, i ogólnie świetne body (NEX-7), gdyby jeszcze AF był szybszy to byłoby body-ideał. Za to optyka w NEX-ach szwankuje. Do tej pory 16/2.8, 30/3.5 czy 50/1.8 niezbyt udane albo kiepskie.

To odwrotnie niż w micro43 które ma za to świetną optykę (choć z najnowszym zoomem 12-50mm Olympus zaliczył wpadkę), stałki małe, optycznie świetne, ale matryce do tej pory były w tyle za NEX-ami.



portret (o ile ekwiwalent 75mm wystarczy) - 50mm f/1.8

"Technically it is not without flaws. It delivers a very sharp center performance but the corners/borders are soft at large apertures. However, considering the typical applications (e.g. portraits) at such settings this is probably not a show-stopper. The image quality is very impressive if you stop down to f/4-f/8 where the lens is almost capable of exploiting the potential of the 24 megapixel Sony sensor. Lateral CAs are slightly visible but not really an issue. The vignetting could be a little lower at f/1.8 though. A real highlight of the Sony lens is the quality of the bokeh which is among the very best that we've seen in this class so far. Portrait photographers will love this aspect!"

macro - 30mm f/3.5

"The Sony E 30mm f/3.5 macro lens delivered a rather disappointing performance on the Sony NEX 7. The center image quality is absolutely great but the border- and especially corner-quality is sub-standard. The rather high amount of lateral CAs isn't helpful either."

"The image quality is generally good around f/8 but avoid large aperture settings. This is a good idea to bypass the rather heavy amount of vignetting at f/3.5 anyway. Image distortions shouldn't be a big issue but we've seen better macro lenses here as well"
