Wygląda na to, że inżynierowie Canona nie lubią 'pixel-peepers' i 'AF-counters'!
Z recenzji na TDP
To test burst rate, I shoot in M mode (wide open aperture, 1/8000 shutter speed), ISO 100, MF, IS off, lens cap on, all noise reduction off and just enough light on for me to see. Odd thing is, the 7D high speed burst rate drops to 4.3 fps in these conditions. It delivers 42-44 frames at 4.3 fps and repeatedly shoots two quick frames after a .75 sec pause. Canon is aware of this anomaly - and I don't know why anyone other than me that would shoot under these conditions. Those were not the numbers I knew this camera could deliver, so turn on the lights and remove the lens cap. With a SanDisk Extreme IV 16GB CF Card (UDMA), the Canon EOS 7D recorded a solid 8 fps for 24 frames followed by a repeating pause and 2 quick shots. The length of the pause starts at around .35 seconds and increases to about .75 seconds around 9 seconds into the burst.
W skrócie - trzeba robić zdjęcia, nie testy (nigdy nie myślałem, że to kiedyś napiszę! :grin::grin
