Two days ago Sony presented new 35mm full-frame DSLR camera A900 in Student Center here in Zagreb. It’s first full-frame 24.5 MP DSLR with stabilization in body!
I had a few shots with it and camera is great. View finder with 100% coverage is excellent, big and bright. People complained that camera is heavy but I found it ok with 895 g, it is after all a full-frame camera. Bad points go to position of Auto focus points which are too close to center.
I tested it only a few minutes so a have only a few shots but here they are (right click -> save as):
ISO 400, 1/90 sec, RAW converted to JPEG in post processing (16.2 MB)
ISO 800, 1/125 sec, RAW converted to JPEG in post processing (16.9 MB)
ISO 1600, 1/200 sec, RAW converted to JPEG in post processing (20.2 MB)
ISO 6400, 1/3000 sec, RAW converted to JPEG in post processing (27.7 MB)
All shots are made with Zeiss ZA Planar T* 85mm f/1.4 ( Sony SAL-85F14Z ) at f/1.4.
As you see there is no visible deference between ISO 400 and 800:
At ISO 1600 and 6400 noise is visible:
ISO 6400, lots of grain, but still, it’s 6400 and the need for it is just in very special occasions.
