It is very very hard to get a good image of any black cat. Sable is very active, very black and even harder to catch.
The F200EXR at 800% DR catches her perfectly. Image has had +2/3 ev exp correction, A touch of sharpening and the WB warmed a touch in Silkypix
1/52 sec, f3.3, 28mm-e, ISO 200, DR Mode at forced 800%DR
