Timings & File Sizes
All tests on this page have been re-run using the production S75, most results are identical, though most notably (and probably one of the most important timings) the shot-to-shot time is now down to 3.6 seconds (from 6 seconds for the pre-production unit), the S75 allows you to take the next shot (buffer space allowing) before it has finished flushing the current image out to the Memory Stick (not true for TIFF or TEXT images).
Overall it's relatively quick, probably limited most by a small internal buffer (just two images at any resolution) and the time it takes the lens to extend (affects start-up times).
Timing Notes: All times calculated as an average of three operations. Unless otherwise stated all timings were made on a 2048 x 1536 FINE JPEG image (approx. 1.3 MB per image). *U

Burst 2 Mode
On thing missing on all Sony digital cameras was any form of continuous shooting mode, the S75 makes a step in the right direction though it's still lacking a real continuous mode. The new "Burst 2" shooting mode allows you to take two frames in a burst (0.7 secs apart; 1.4 fps equiv.) it's there, I'm not sure how useful it is but at least Sony have recognised their weakness and have at least partially addressed it. To summarise: *U
- Two frames 0.7 secs apart, wait 6 seconds before you can take the next burst.
File Flush / Display Timing
There are three timings below, I'll describe each in turn:
- Time to process - this is the amount of time after pressing
the shutter release button before the camera returns control to you,
the image may still be being written away to the Memory Stick but you
can begin to take the next shot.
- Time to flush - this is the amount of time it takes the camera
to process and flush; complete writing the image to the Memory Stick.
It is taken from the moment the shutter release is pressed to the moment
the red light beside the Memory Stick slot (inside the compartment)
goes out. This timing includes the time to process.
- Time to display - this is the amount of time it takes the camera to display the image, most digital cameras first display a rough version of the image (a thumbnail from the file header) and then load the full resolution image, you can't manipulate the image until it is fully loaded (magnify etc.) however you can interrupt this loading process skip to the next image.
The S75 appears to have enough buffer space to hold a maximum of two images at a time (which makes sense when you consider the Burst 2 mode), so it's possible to snap a shot and still have space for one more.

* All file sizes are an average of three files. As is the case with JPEG it's difficult to predict the size of an image because it will vary a fair amount depending on the content of the image (especially the amount of detail captured). For example, take a photograph of a fairly empty wall and you'll get a small JPEG, take a photograph of a bush with a lot of detail and you'll get a larger image. File sizes here are closer to the later, the larger size of file you should expect.
** Majority of this time is spent processing (generating) the GIF file.
Excellent, just as we'd expected. The S75 uses the same powerful NP-FM50 "M series" InfoLithium (Lithium-Ion) battery we saw in the S70 (rated at 7.2V 8.5Wh, 1200mAh). On a full charge the camera reports over 130 minutes remaining, in our tests this appeared to fairly accurate, indeed on many occasions with judicious use of the LCD the camera will last a good days "outing" without need for a second battery. Add to this in-camera charging and supplied charger / AC adapter and you have to say that one thing Sony do very well is rechargeable power. Very, very good indeed.
