hi guys,
i am wanting to purchase a 7d, as i cant wait for the long over due 1dsmk4 to do video.
but i will also want to do fast fps with the motor-drive. on the specs it says it can shoot 8fps.
last night i rented a 7d to try to shoot some action at 8fs. everything we tried (several hours of mucking around with it), we couldn't get the camera to shoot faster than 4fps when shooting dark subjects, but got 8fps when shooting bright light.
we aren't new to canons, and know most of the controls that effect frame rate (ive used almost every canon professional camera, over 20 years).
here are the settings tried with no success at improving the frame rate-
- lens set at manual focus- so no slowing down for camera to focus.
- camera set on manual, with faster that 250th sec shutter speed.
- we tried raw only
- we tried small jpegs only.
- all testing was done at the first part of the buffer -ie, waited for the buffer to clear before trying again.
- we used a sandisk extreme 4 card (one of the fastest available).
- i also tried a different card.
- of cause- the camera was set at "H" on drive settings
we wondered if lots of noise would be causing the slow down from shooting the dark stuff, but when i tested with well exposed flash lit subjects with the modeling lamps off with very fast strobes(capable of over 12fps recharge), the camera still went very slow . so that throws out the idea of noisy files slowing things down.
the issue isn't an isolated one, and appears to do the same with the latest firmware.
http://photography-on-the.net/forum/showth...9335&page=5reading this thread, apparently there is no slowdown when using only live view. this of cause isn't an answer to the problem though.
have you guys got any answers (hidden custom functions??)? i really want this camera to shoot at the speed that the canon specs say they do.
thanks paul
