Re: D4s has smaller RAW buffer than D4??
In reply to DudleyG, 7 months ago

I just ran a quick test with the D4 and the D4s using the same lens.

I took AF-C sequence of about 15 shots (jpeg - large - fine) with D4s using the Sony 32gb(N) XQD card and the light stayed on about 5 seconds.

I then put the Sony 16gb(H) XQD card in the D4s, took 15 shots, and the light also stayed on for about 5 seconds.

I then put the 32gb(N) card in the D4, took 15 shots and the light was only on about 2 or 3 seconds. I then put the 16gb(H) card in the D4, took 15 shots and the light was only on 2 or 3 seconds.

Bottom line, the green light stays on a lot longer on the D4s while writing to the card than on the D4. It has me wondering if the D4s isn't clearing the buffer and/or writing to the card as fast as the D4 can. For what it is worth, I have the latest firmware 1.10 on the D4.

If that is so, that would help explain why the buffer fills up faster on the D4s than on the D4 if the D4s can't clear the buffer as well as the D4.
