Erste Eindrücke zur A77 auf Lu-La

Auszug: The EVF

The EVF on the A77 is the largest, brightest, highest resolution and most contrasty electronic viewfinder yet, from anyone. Incidentely, it is the same 2.4 MP OLED device as the one on the A65, the NEX-7, and the FDA-EV1 accessory viewfinder for the NEX-5N.
Is it good? Yes, it's very good – for an EVF. I would go so far as to say that it is much preferable to the dim and small reflex viewfinders found on most reduced frame DSLRs. This then begs the question – how does it compare to the viewfinder on a full frame DSLR like the Sony A900.
Not so well. The viewfinder on the A900 is one of the brightest and largest found on any 35mm DSLR – ever. Sony's new OLED EVF, as good as it is, is up against what may the gold standard, and it doesn't quite deliver.

The area where I find EVFs to be problematic is in high contrast situations. As one moves from bright to dark areas the viewfinder's brightness pumps. I find this distracting. An optical viewfinder allows the eye to compensate for brightness differences, while an EVF (even one as good as Sony's new one) does its own compensation.
Outdoors the A77's viewfinder does the job, though shadow areas can become blocked up. In low light I find that it gives an unrealistically bright and contrasty impression of the scene in front of it, and also one that gets grainy as the VF's amplification is boosted to enhance visibility.
My analysis (and unlike some current US politicians I reserve the right to change my mind based on further experience and evaluation), is that the new Sony EVF is the best yet from any manufacturer, beats most low-end APS-C reflex mirror systems, but still isn't a patch on a good prism system.
Of course a good EVF allows overlays, such as live histogram and electronic level, not to mention in-viewfinder postview and playback. There are obviously lots of pros and cons to consider and no one right choice. Quelle: Luminous-Landscape.com
