5. Normal buffer depth (RAW only, ISO100, with “record” function set to “Standard”, just the CF card in the respective slot).
This was in tune with specs (21 shots) with me getting 19, 20 and 21 shots before fps drop in 3 consecutive AIS/High-fps series.
6. "Buffer rate in DPRAW option enabled with just cf card inside".
This was above specs (7shots). I got 9, 12 and 14 shots in 3 consecutive AIS/High-fps runs, pointing at different areas before the FPS rate dropped.
7. "Same as above but with a SD card inside shooting large jpegs and DPRAW in the cf card (does the sd card slot gimp the buffer rate?)"
I found this request a bit odd and thought it would make more sense making it the other way around, so I set the “record” function to “Rec. Separately”, with RAW going to the SD and large Jpegs to the CF card. I got 10, 11 and 11 shots before fps drop in those conditions.
8. Now for the impressive bit: I repeated test 5) but with just the SD card in slot 2 and to my (our) amazement the buffer would simply not top-up, with throughput to the card of such an high number of frames that I had to eventually give up and cut the shutter.
We found this odd and made sure that everything was set as in 5) above (RAW only, ISO100, with “record” function set to “Standard”, just the SD card in the respective slot, AIS and high-speed drive engaged) and repeated the test. Same results.
I was, like, “Pretty impressive, no?” and he was, like “Yes...” but immediately added “but we don’t make this claim”, lol...
