#34. "RE: Don't forget about your lens selections for this bad boy" In response to In response to 31
One thing to keep in mind, that even though the sensor might have more resolution than the lens, it doesn't mean it's a bad image, just that you aren't utilizing the potential of the camera. If whatever you had been shooting with a D700 provided the quality you needed then you will get at least that on the D800. It's not like you're taking a step backward, it's just that you have more possible steps forward.
I have the 70-200 II right now. I used to have the 70-200 I. On the D700 I didn't really see much of a difference between the two wide open at most focal lengths. The II was a bit sharper from F/4+. Things might be different on the D800, but given the resolving power of both lenses I would expect them to hold up quite well. The I "in general" has "slightly" softer borders and corners over the II, but on the D700 I really didn't see much of a difference. Maybe we'll notice that difference more on the D800.
I think one thing that people may not be as happy with is using the I with a 1.4X, 1.7X or 2X on a D800. A 1.4X was doable on the D700, especially at F/5.6+, but that won't be the case on the D800. You'll need F/8 to meet the D800 sensor res. Not saying that wide open it will be horrible, just not much better than you already get with the D700 Better in the center but the edges/corners won't improve much, if any. And if you don't care about the edges and corners being softer then it does't really matter. We're just talking overall across the frame performance.
I haven't done much video but I have a friend that does. He's more concerned about moire than I am, but until we start seeing some video from D800E's against moire inducing fabrics and such we won't really know how big an issue it is.
