Well it’s not that the Nikons, under the D200, don’t function with “a whole pile of lenses”, they just will not use the auto exposure modes with manual lenses. They can’t use the onboard light meter. However, digital photograph has given us a whole new dimension to exposure metering with the histogram. Given that digital shots are free using the histogram to determine exposure is easier than a hand held light meter. If someone doesn’t want to shoot manually, don’t use manual lenses.
Oh, you Canon fanatics. You’re as bad as … us Nikon fanatics.
