Question: what batteries? last question:I'm seeing in some reviews that nimh batteries are best.  Others say the lithium ones are best.  Can anyone comment on this?  Thank you all for your answers.
Document: I even did comparisons with my H2, and the Canon S5 IS definitely produces better quality photos. I look forward to really getting this camera out more! !Edited: I ended up returning the camera after seeing photos that were taken with the Panasonic DMC FZ18. The Canon has many neat features and does produce very nice photos, but the end product is better with the Panasonic in my opinion. In addition, the Panasonic uses a rechargeable Lithium battery, which is an improvement over the Canon's four AA batteries.
I did a lot of research before buying this camera. I am basically happy with it. The controls are much more accessible than with small point-and-shoots. I like that it uses regular NiMH AA batteries, and they last a long time.That said "there is no magic". This is a camera with a small sensor and a lot of zoom. It needs light to take good pictures. It is far better off when shooting at ISO 200 or below.
I have had my camera for about a month and a half now, and I'm totally pleased with the pictures it takes! The zoom is amazing and doesn't get as grainy as others I have used in the past. The battery life (uses 4 AA batteries) is remarkable and much better than I had expected. Has the ability to take pictures while shooting video (although you end up with a freeze frame in your video).
I'm very happy with the S5 I bought to replace an S3 -- except, as noted elesewhere, I hate that the SD card is now in the battery compartment. The hot shoe (external flash socket) is a HUGE help, since the builtin flash on these cameras is pretty wimpy. The camera takes unbelievably good pictures and has excellent first shot and shot-to-shot times (it helps if you use the Energizer e2 Lithium Batteries).
It gets annoying, but you just have to be extra careful. I wouldn't say that's a reason not to buy this camera though. I would advise in purchasing a good quality camera bag and lens cleaner in case you are like me and keep the lens cap off most of the time. I have been pleasantly surprised with how well the batteries last in this camera- this too depends on how much you are using the flash, zoom and other features.
Is anyone else as flummoxed by the negative consumer and expert reviews of this camera as I am? If I were paranoid, I'd think a conspiracy existed to drive down the cost of this remarkable camera.The range of controls is very broad, their setup is intuitive, and the camera's performance is exemplary. Not only am I pleased with how the camera handles and what it will do, but I'm WAY pleased with the images it produces.
The camera is bought for its value. I m satisfied with the price and its value. It was delivered on time as described on the website.Coming to the camera review, after all reviews accross the web, I found this the best in digital camera category. Next to this would be a SLR.The features like face detection,shutter speed , image stabilization technology are awsome.The batteries consumption is just ok.One drawback I found is tat shooting pictures in night mode.
Others  like I said, who have more experience with this type of camera may jump right in and feel at home with it. I would say that it is a great purchase for someone who wants to learn more about digital photography by leaving their point and shoot behind and not have to worry about buying another camera in a few years or more. Just be ready to take a BIG STEP!At 8 megipixals and 12x optical zoom I find that I really don't need anymore even though it is out there to buy.
We bought this camera largely based on reviews of others and to upgrade to a more manual, higher quality point and shoot. We were amazed by its video capabilities. Others give similar praise. Where we were disappointed was in the quality of the stills. The auto focus is hit and miss. My $200 Sony does better in this category. Maybe a quarter of the indoor photos we took were slightly out of focus. That's hard to forgive, but unforgiveable is the flash.
We usually use rechargeable NiMH AA batteries, but can also use regular alkaline AA batteries, which saves worrying with a charger on longer trips. The pictures display well on either a portable computer or even larger flat screen tv's.
Answer: Low self-discharge NiMH cells (such as Sanyo eneloop and Rayovac Hybrid) are rechargeable just like regular NiMH cells. But unlike regular NiMH cells which lose their charge within a few weeks, those LSD cells can retain 80% of thier charge for up to 1 year. That means they have both the advantages of rechargeable (high power, low operating cost) and alkaline (long storage life).Read my reviews on "Sanyo eneloop battery charging kit" to learn more.
