Timings & File Sizes

Timing Notes: All times calculated as an average of three operations. Unless otherwise stated all timings were made on a 2400 x 1800 NORMAL quality JPEG image (around 740 KB).

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.

OFF to Shot Taken   2.2 Very Fast

This little snapper is VERY VERY FAST... Aided by having no zoom mechanism it takes just 1.8 seconds to open the metal lens cover, extend the lens and be powered up and ready to shoot. And because of the fixed lens focus speeds are very fast (except macro focus which hunts a little). This is (so far) the fastest camera in our "Off to Shot Taken" test.. Put simply this means that if you pick up the camera you can have it switched on and a shot taken just in 2.2 seconds.

* 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

Here we'd normally test how many shots can be taken in a row before you have to wait for the internal buffer to be flushed out to the storage card. Well, I don't know how Fujifilm have done it but even at full size / resolution (2400 x 1800 JPEG FINE about 1.6MB per image) you NEVER have to wait between shots, in fact you can get an average of about 2.5 seconds between shots shooting until the card fills up... An amazing performance for such a little camera (lets hope this technology development is going into the upcoming 4900Z).


File Flush Timing

Timings shown below are the time taken for the camera to "flush" the image out to the SmartMedia card (when activity indicator next to the viewfnider stops flashing). As with most modern digital cameras the 40i continues to write data out to the SmartMedia card in parallel with other camera operations (which explains why you don't have to wait between shots).

The estimated number of images per 8 MB SmartMedia card is given as a guide to beginners (as that's what's bundled with the camera - bundle may differ by region).

Battery life

Battey life wasn't as good as we'd have liked (probably because the camera only uses two batteries), using the LCD to frame the shots the two 1600mAh NiMH's provided lasted about an hour and around 80 images, so taking a spare set of batteries with you when you go out is a good idea. Add to that any battery usage from listening to MP3's and you'll have to be real careful that you have enough batteries with you. Having said that, Kudos to Fujifilm for supplying what a probably the most powerful NiMH on the market (1600mAh). (Battery life for MP3 playback is discussed in the Music section of this review).
