| p.1 #3 · burst speed and buffer depth - Is it affected by file size? |
You would think so, but not necessarily. The 7D had an odd behavior before the latest firmware update when shooting RAW+jpg. The buffer was always limited to 7, and that didn't change even if you used sRAW+low rez jpg.
As Paul noted, some of that was probably the conversion to jpg, but you'd still think that the huge difference in file sizes would have some effect.
In that case, it seemed like it was more a firmware limitation than an actual processing speed issue. And the dramatic increase in RAW+jpg buffer from the new firmware seems to bear that out.
I think you'll just have to play with it. The buffer size in the viewfinder should give you a pretty good idea.
