Battery Performance

Our general method for battery testing is to reset the camera to its default settings and change the recording mode to the highest quality option. Then, we take 5 pictures without the flash and 2 pictures with the flash until the battery is dead. For more information on our battery test, please refer to our Testing Procedures page. For this test, we used the supplied proprietary batteries for the Canon S410 and the Casio Ex-Z40. For the Pentax Optio S40, we used our pair of NiMH Power2000 2500mAh batteries. All batteries were fully drained before charging for the test.

   Number of shots taken in one battery charge
Canon S410 610
Casio Z40 1,767
Pentax S40 1,236

The Casio Z40 showed a really outstanding performance, taking 1,767 frames on a single charge with its 1230mAh rechargeable NP-40. The Pentax S40 also performed very well, shooting 1,236 frames on our 2500mAh Power2000 NiMH batteries. The 840mAh NB-1LH rechargeable battery provided the Canon S410 with 610 frames on one charge. Although, the Canon S410 took the least number of frames, all three cameras proved to have extraordinary battery performance. Keep in mind that casual use of any of these cameras will result in lower numbers than we were able to achieve. Our test consists of shooting continuously until the battery is dead.

    #11: For the continuous drive section of the specs, we use the results of our test. Canon is rated at 2.5 fps, but we found that in the highest resolution and SuperFine mode, we were able to take 3 shots at 2.8 fps.

    Thanks, I'll add a little note in the specs table.

    i love my S230 with its 640x480 video capability. Believe me, once you get started with vids and a good editing program like Vegas you wont get back and pics are only the bonus :) And all that fun with such a tiny cam :)

    I consider the picture quality/optics of the Canon Powershots "ok" - if you consider it's a shoot and point and not a SLR with hyper-great image quality/zoom etc.

    Its picture quality is 'overall good' - a great allround camera with nice features (esp. the vids :). I would prefer my S230 (or newer) any time over a big/bulky camera.

    Pros:
    nice 640x480 vids
    IQ good for a point/shoot
    size
    stylish

    Cons:
    weak zoom

    Also, the continous drive information for the cannon in the specifications table is wrong.

    The "best pictures" of this lot of cameras are almost a given; the S410 has a sensor of the same generation with an area of 38.2mm(1/1.8"), as compared to the others, which have 24.7mm (1/2.5") sensors.

    What would be more interesting would be a comparison of newer cameras by major manufacturers; generally they now all come with 1/2.5" sensors, including the new canons.

    #8, Unfortunately, we were limited by which cameras we could choose and the S4i was unavailable at the time. However, we feel that the S40 is comparable to the other two cameras with respect to exposure options, size, etc. The S4i would have been a good option and we would have included it if it was available.

    How come the S4i wasn't reviewed? Isn't it more of an appropriate comparison?

    I looked at the Canon S series - they are very nice - almost bought one - THEN I found the Pentax Optio 33WR (now it's upgraded to 4 MP and called the Optio 43WR).

    It's WONDERFUL.

    First of all, it's highly water resistant, has gaskets all through it.

    Has about 13 programmed modes but I never need them really I just point and shoot and things look great. White balance is always right on.
    Panorama/stitch modes, close-up modes, etc.

    Takes SD cards.

    Quicktime movies are a bit cheesy (320 X 160) it's more the sound I have issues with than anything but most of the time it's acceptable.

    I'm guessing the Pentax 43WR goes for around 280 bucks - havent checked lately.

    If you want a camera you can take skiing, snowboarding, to the beach or stand out in the rain without worrying about damage to the electronics, this is the one. It's also not gooney looking (i.e. bright yellow etc) like some other water resistant cameras.

    #5 thanks, I have fixed the mistake
  • Gumbico - Tuesday, October 5, 2004 - link

    Actually, the S410 only allows 3 mins of vid time. That's my only gripe about this camera.

    I have the Canon and I couldn’t be happier. I’ve never been one to read through a manual and this camera was easy enough to figure out so I did not have to do so. I am always surprised at how crisp the pictures are. Of course, I am not a professional photographer but this camera provides everything that I want in a camera – good pictures and small size because I hate carrying stuff around.
