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 the Nikon Coolpix 4100 and the Pentax Optio S40, we used our pair of NiMH Power2000 2500mAh batteries. For the other cameras, we used the included battery packs. All batteries were fully drained before charging for the test.

Number of shots taken in one battery charge
Casio EX-Z40 1,767
Nikon 4100 1,315
Pentax S40 1,236
Canon SD300 1,028
Olympus Verve 400

In our battery test, the Nikon 4100 puts in a very respectable performance - shooting 1,315 frames on a single charge. We highly recommend getting some high-powered NiMH batteries. They put in a far superior performance to alkaline batteries and are much more cost effective.

    Pardons for continuing the OT thread...

    "Barf" is Farsi for "snow", and a popular brand of laundry detergent and shampoo available at any corner store in Iran. In the same vein, a "barfi" is the guy who shovels the snow off of your roof.

    I was looking at Nikon, but bought a Kodak DX7440 instead. This gives you a good lens which has very little barrel distortion compared to all Nikon point and shoot. Plus manual settings for EVERYTHING and near instant shutter response, that Nikon's line lacks.

    The only bad thing about P&S cameras, are the 4:3 ratio of the pictures. I'd rather 35mm film ratio of 3:2, like all SLR cameras got.

    Camera reviews...

    Epinions is worthwhile sometimes, and as someone else mentioned, dcresource is good. Another one I found valuable is Steve's Digicams (

    The Canon A75/A510 and A85/A520 were models I had considered, and I was all set to purchase an A85 after the 520 was released and the prices on the A85 dropped significantly.

    However, the Nikon Coolpix 5400 was just too good a deal to pass up. :-)

    Magnesium case, 5.1 MP, ED lens, flash hotshoe, LCD screen that swivels, diopter adjustment for the viewfinder... it's a level above any of the Canon 75/85/95 etc. models.

    There are only two drawbacks to the 5400 (and some other Nikons).

    One is that it takes a Li-ion battery pack. You can also use a standard Lithium disposable battery in an emergency. The good thing is that other companies make replacement packs that are cheaper than Nikon's. I was against this type of pack and wanted a camera that takes AA cells. I decided I can bend a little since the 5400 has so much else to offer.

    The other drawback is the lack of an auto-focus helper light for low-light conditions. It hasn't proved to be a problem yet, and I plan to get a cheap LED pointer and use that if needed.

    hoppa here is one review of Canon A510/520 I have been able to dig up:

    I seems that A520 is a total waste of money since quality is not improved and due to larger files it is a bit slower and it even has more noise, so it's A510 all the way. I bought one and I am very happy with it. LOVE the all manual controls and it's very snappy.

    Even movies are much better than I expected from 320x240@15 FPS up to 3 mins. Perfectly OK for goofying around, since this is primarily a still and not a movie camera. Even so it still puts this Nikon to shame.

    Lens is a bit soft in corners at wider apertures, so I use Aperture Value at 5.5 to 7.1 and the quality is great.

    Overall I think it is _the_ best camera for the money, I'm just having some strange problems when the camera refuses to shoot with flash and then tells me to change the batteries and turns off even though the batteries are far from depleted and even new fresh from the charger don't help. It happened twice in two weeks since I have it and is very annoying, since it comes out of the blue and disappears as mysteriously as it appears. Thankfully I bought it at a local camera shop so RMAing it will be easy.

    Thanks for the review. You guys should really review the new Canon A510/520. From what I've seen they (at least the 510) blow everything else in the price range away. Compared to the entry-level Nikons, they offer full manual controls, longer lenses and much sharper pictures. Certainly seems like a better choice to me. Reply
