Originally posted by Rondec The issue with the D600 isn't its sensor though, it is the fact that Nikon has crippled its body in comparison to the D600. I would be very satisfied with a D600 sensor in a Pentax body, just so the shutter speed isn't crippled and there is still sealing, etc.
I shoot very much wide open with my D600 and 1.8 lenses. I was honestly afraid the 1/4000 speed, that people think is a limitation, would be a problem. In reality, its not... In sunny winter days, sure, the shutter speed often go max. But its not a problem... The camera handles it pretty well, sometimes clipping out the most extreme highs. But i can see that exposure in Matrix metering has some leverage at 1/4000. Or, ill just stop down to 2.2 or 2.8 wich is still good enough for subject isolation anyway.
Remember... All those people that have been shooting D700.. Base ISO 200 and 1/8000, no one complains. and that is kinda the same as ISO 100 and 1/4000.
Imho, the difference between shutterspeeds from 1/4000 to 1/8000 is a very exagerated problem that people only see when they stare blindly at rumors and camera specs.
But sure, there are people to wich the 1/8000 are a absolute necesity for their shooting style. I can understand that.
And pentaxians would go berserk if there was a Pentax FF with only 1/4000
