Timings & File Sizes

Timing Notes: All times calculated as an average of three operations. Unless otherwise stated all timings were made on a 2048 x 1536 JPEG (***) image (around 800 KB per image).

File Size Notes: 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.

Symbols: ~ = roughly / approximately.

Play: INDEX thumbnail view (2 x 2) <1.0  
Play: Zoom-in <1.0  
Auto Focus LAG 0.6 - 1.6 Best case is 0.6 seconds *
Shutter Release LAG 0.1 Fast *
Total LAG ~0.7 No pre-focus, one complete press *
OFF to Shot Taken 7.8  

Once you've got it powered up and that lens mechanism has extended the 3000Z is really quite fast, showing fast Auto Focus times and fast shutter lag you can quickly click-click-click through the shots without much delay.

* LAG times are often misunderstood and so are described below:

Auto Focus LAG is (roughly) the amount of time it takes the camera to auto focus (a half-press and hold of the shutter release button), this timing is normally the most variable as its affected by the subject matter, current focus position, still or moving subject etc. This timing is an average.

Shutter Release LAG is the amount of time it takes to take the shot after auto focus, this timing assumes you have already focused (half-pressed the shutter release) and now press the shutter release button all the way down to take the shot. This timing is an average.

Total LAG is the total time it takes (not just the two above added together) if you haven't pre-focused, that is no finger touching the shutter release button, press it all the way down in one movement, this new timing is how long it would take if you were in one of those spur-of-the-moment situations. This timing is an average.


Maximum shots in a row

The table below defines the maximum number of shots which can be taken in a row before the camera makes you wait (measured as "wait before restarting") for space to become available in the internal buffer.

Size / Resolution
 
Maximum shots
in a row
Wait before restarting
2048 x 1536 Super-Fine (***) 4 5.6 secs
2048 x 1536 Fine (**) 9 3.0 secs
640 x 480 Standard (*) >50 n/a


Continuous / Movie Modes

The PhotoPC 3000Z has one continuous (burst) shooting mode and one Movie mode.

Continuous Mode Image Size Quality Approx. frames
per sec (LCD on)
Max no. of frames
Continuous 2048 x 1536 *** 1.6 fps 3
Continuous 2048 x 1536 ** 1.5 fps 7
Continuous 640 x 480 * 1.4 fps 41
Movie 320 x 240 MOV 15.0 fps (25 secs)


File Flush Timing

Timings shown below are the time taken for the camera to "flush" the image out to the Compact Flash card (when CF activity indicator on the top LCD panel stops animating). The PhotoPC 3000Z continues to write data out from the internal buffer to the Compact Flash card in parallel to your shooting the next shot, that means that the times below do NOT represent how long you have to wait between shots, that delay is less than 1 second (other than for HyPict or TIFF images).

The estimated number of images per 16 MB Compact Flash card is given as a guide to beginners (as that's what's bundled with the camera - bundle may differ by region).

Battery life

I mentioned this earlier in the review but Kudos again to Epson for supplying an excellent set of 1500 mAh NiMH rechargeable batteries and a charger. Digital cameras which take AA style batteries are pretty much useless without a good set of NiMH rechargeable and Epson haven't ignored that fact. The batteries supplied will last for ages and ages, with careful use of the LCD (switching it off between shots) or by using just the viewfinder you should be able to last half a day or more on a single charge.
