My understanding of Rob's position is that he wants the best high ISO performance possible. That is somewhat dictated by the size of the sensor. Two sensors of similar of pixel count, one being larger than the other, the larger one will have better high ISO performance. This is due to the size of each individual R/G/B cell in the sensor. So with the Canon 5D being a full frame sized sensor and the Nikon D200 being and APS size, you can get a reasonable measurement of performance between them. Yes you can use software to minimize noise, but basically at the expense of detail. So Rob can do a pretty good ballpark estimate based on existing images out there.
If the D200 is adequate, then he might be able to wait on Pentax for their version. If the D200 is clearly not adequate, then he can move on to the Canon 5D. In a previous post he pretty much indicated that a larger sensor was really the direction that he wanted to go. Hence, my post. -- Best regards, Bruce Monday, February 27, 2006, 9:04:07 AM, you wrote: SB> Hi Bruce, SB> Wouldn't the quality of the images be different depending on how they were SB> processed in the camera?
