Re: Consecutive Shooting With *ist D

Thanks to everyone who pointed out that (of course!) images go into the 
buffer in Raw format. This hadn't occurred to me. So the buffer size is, 
indeed, perhaps 45 - 50 mb.

Consecutive Shooting With *ist D

[Joseph Tainter]

I wanted to see what it could do. In Raw mode, the answer is 5 frames. 
Then it pauses for a long time before you can take another. I assumed 
that this was due to the size of the buffer, so I tried it in Tiff mode. 
Again, it shot 5 consecutive frames before it had to pause to catch its 
breath. This means that the buffer holds at least 85 mb. It also means 
that the buffer could have held 6 Raw photos (13 mb apiece) in 
consecutive mode. So the buffer size is not the limiting factor. I tried 
it again at highest jpeg. Again it took 5 shots before pausing, but 
recovered and took number 6 much quicker that in Raw or Tiff.

So does the processor's capability set the limitation on consecutive 
mode shooting?

A questionable assumption.  The buffer almost certainly holds the images in
a format very close to raw mode, before any time has been spent processing.
It's probably fairly close to 64MB in size (5 x 12MB, plus settings).

The conversion to the selected output mode (plus adding thumbnail images)
will take place as the images are read from the buffer and written out to
the CF card.
