Hi, I'd like to know if anyone has actually measured the D300 frame rate when shooting in 8 fps mode using the battery grip and if so, what rate you measured. I recently found out about the bracket burst trick of getting more than 6 fps without the grip. Just by listening to the camera sound, it is obviously shooting at a rate higher than 6 fps but I was curious what the actual rate was so I measured it and found it to be about 7.25 fps. I did this by using a microphone next to the camera to record the mechanical sounds during the shoot and then I analyzed the audio waveform to measure the peak-to-peak timings. (BTW, I also measured the non-burst rate and found it to be very close to 6 as expected). I don't have a battery grip and hence can't perform this measurement to see if the camera actually gets close to 8 fps. (Maybe the rate with the grip is also 7.25 fps and Nikon is "rounding up" the spec.) Has anyone done a simliar rate analysis with the battery grip and if so, what rate do you get? I'm considering getting the grip and wanted to know if I would get an fps benefit. Thanks.
