Don,Warning - I'm in a grumpy mood....
It's getting very tiring reading about how this camera is better than that one and the entire world as we know it is just about done.
This happens each and every time any camera manufacture releases its' newest and best camera. Saw it when the 1Ds was introduced, then again with the 1DsII and yet again with the 1DsIII (I use Canon as I really don't have any experience with Nikon). How 'bout when Phase introduced the P65+? People went nuts over it saying how medium format would never be the same and how the P65 was such a game changer. That is until the IQ backs were introduced.
Reminds me of the early days of personal computers where a new improved model was being introduced at a rate of several every 6-months.
Then there's the small sensor and 4/3's cameras.
Why do we have this compulsion to comparing different camera sensors? A 35mm camera is just that, 35mm. A full size 35mm sensor is 36x24mm. A medium format sensor is 53.9x40.4mm. At this point I really couldn't care less that there's a 35mm camera that offers 36 megapixels because no matter how you slice it, it remains what it is - 35mm and I choose not to use 35mm.
I'm not trying to bash 35mm. I'm very pleased to see that Nikon has developed a 36 megapixel 35mm camera and hope Canon will soon follow. I'm of the opinion that what Nikon has done is change the face of 35mm photography as we now know it; however, no matter the megapixel the sensor remains that of 35mm. It's very close to saying you can make a silk purse out of a pigs ear.
Again the grumpy warning...
If you feel that a high megapixel 35mm camera is "the end of medium format superiority" then you're misinformed as to what medium format brings to the table. This is close to saying medium format is superior to large format. While medium format has closed the gap that gap like the one between 35mm and medium format will always be there.
Still grumpy but at least I have it off my chest.
just instead of writing all this - give it a try, get a D800E and try it with some good glass. You will be pleased
