Re: non-full RAW files

[Randy Little <randyslittle@xxxxxxxxx>]

of course the burst rate is affected by the capture size.   Burst rate is limited by memory on board before transferring the files to the card.   And Quality will not be affected at all.  Only dimensions.  Back to burst rate this is exactly how the Sony A99 increases its burst rate from 6 fps to 10fps.   Its also basically how my Leaf Aptus goes from  .9 to 1.2 fps and a 10 frame burst rate to unlimited burst rate.  (its using compression vs  not compressed raw.)

Well, that may very well be, but if Canon's own site didn't mention that,
I wouldn't guarantee that those smaller raw captures will necessarily
speed up the burst rate. Certainly, the writes to the card will be faster,
but there is a physical limit on the burst rate of a given camera which
smaller files would not affect. And if the card write speed was limiting,
then you should be able to speed up the burst rate by simply getting a
faster card.
