Update: the ISO 3200 is not the maximum value but rather a comment from the photographer that ISO 3200 was very usable. Also, it was mentioned in the comments that this could be the replacement of the D300s (info sent by some native speakers - thanks).
This rumor came from the World Wide Web and I cannot vouch for its validity (thanks to everyone who sent that in).
The Russian nature photographer Igor Shpilenok has arrived in Kamchatka for 10 days and the rumor is that he will be testing a new camera from unidentified company (hint: he is a Nikon shooter, check his blog). The rumored specs are:
- 20MP crop sensor
- HD movie mode
- 10 frames per second
- single CF card slot
- working ISO: 3200
I am not sure if the camera on the picture is the actual test piece or just a reference photo (the Nikon logo is taped):
