Or an 18 megapixel high ISO D90 replacement?
So what would make you "enthusiast DSLR users" happiest?
I don't want video, and can't comment on EVIL, don't know about it.
I doubt that you can get both high ISO and 18 MP in a D900 replacement. What sensor would it be? I have been looking at the DXOMark data, and it appears to me that the D90 is already a very well designed camera. Essentially identical in noise performance to the D3x, better than the D300s. It is only beaten in noise/ISO performance by the D700 and the D3s. The larger sensor area of those two suggest it will take a large chip improvement to overcome the sensor area difference.
I understand that Nikon needs to up the pixel count to compete with Canon, but what enthusiast lens will you use that can benefit from more sensor resolution and not be lens limited with an APS sensor?
What I would really like is a good pivoting display, and ability to 'read' the index rings on my old AI lenses. But I tried the D5000 in the store, and did not like the bottom hinge design for the display. I would love an ISO boost.
I have about talked myself into buying a D90 with the two kit lenses, and the price is dropping. I see the 2 lens kit now for $1550. I may need intervention before I succumb to NAS.
