Memory buffer upgrade If anyone knows more about it there should be a discussion of the memory buffer upgrade Why for example does doubling the memory result is more than double from 28 to 68 the number of shots in NEF RAW 12 bit lossless compressed mode FX mode but no increase at all in small JPGs it remains at 130 I suspect this is related to the fact that small files can be shited to main memory at a rate close to the maximum frame rate of the camera but much larger files can t be transfered as quickly But a more detailed explanation would be useful
