Question: batteries I am interested in this camera and the A590 but am a bit turned off with the idea of using AA batteries.  Can anyone, who has used both AA batteries and the battery packs, tell me what are the advantages/disadvantages and which they recommend?  Im going on a trip and want to get a new camera so Im trying to pick something convenient for travel.  Also I will be travelling out of the country (already got a converter set).  Any advice would be appreciated!
Document: Suggest you look at some of the other highly rated models. Do not pick this one if you can only get the version that uses AA batteries. We could not get through a single day of moderate use without going through 4 or even 6 new batteries. The camera works fine and the quality of the pictures is good. If you are just interested in something to shoot some pix with, there may be too many bells and whistles on this for you.
This is a great purchase. You definitely need to purchase a photo card with more space. I also kept extra AA batteries with me in case, but used the camera for a 2 wk trip & never needed to replace them. The only other thing I would recommend is to find a screen protector, even in the case, mine is now a bit scratched. But I love the large screen, the video footage with sound, the zoom & everything else about this camera.
I take my movies on Standard mode 640x480 30fps. By using that you'll get the clarity of almost HD movies. Oh, I use rechargeable Ni-MH AA batteries. I was in Denver, CO for three days last month and took 150 photos and three movies on one set of rechargeable AAs, and they still had juice in them when I got home. I also use a 16GB memory so I'll won't run out, but I do carry a 4GB SanDick ExtremeIII memory card as backup.
Canon Powershot SX110IS 9MP Digital Camera with 10x Optical Image Stabilized Zoom (Black)I took this camera on a 5 week travel trip across the US and got the most amazing photographs; even a professional photographer was impressed with the clarity, especially when we practiced "drive by" photography while speeding down the highway at 70mph. The only drawback is there is no view finder, so after trying to look through the flash attachment a couple of times, I figured out that wasn't going to work.
I really love this camera, i've had it for awhile now, 8 months. First my negatives are that the Flash is super slow, and trying to take sport shots is horrible. That might be user error though. I was scared to get a camera that uses double AA, but I got energizer batteries and i take millions of pictures and my camera never dies. On a recent week long trip to cali i took atleast 200 pics and never had to charge my batteries.
This is the best camera I have ever owned! The pictures are crystal clear, and I never get a fuzzy picture. I have two small children and I can set the camera to the kids and pets setting and get great quick shots of them. We just took it to the snow and got great shots of the kids, and great video as well! I would recommend this camera to anyone and everyone!
Macro shooting is amazing. You can practically touch the subject with the lens and get a clear, very detailed shot!If you want a quick convenient camera for casual shooting, don't really care about too much zoom, don't get this camera. Get something smaller and faster, and something that comes with a rechargeable lithium battery. I would stick to Nikons, Sonys and Canons. This one takes two AA's, and dealing with those has its pros and cons.
Both a good and a bad thing, although mostly good since you can change batteries when in the field or find extras at a local shop.+Direct-Print to printer with a USB cable (I've never used this, but could be useful and convenient for some)Cons:-Okay battery life. Battery can be used quickly  when using the flash a lot or using optical zoom often. Setting the LCD brightness down can help. I bought High-Capacity rechargeable AA batteries and these helped a lot.
Runs for about 2 weeks (used almost every day) on 2 AA rechargeable NiMH batteries from Energizer. I use an 8gb SDHC card from SanDisk and love it. My only gripe is that when it came new in box there was a screw missing from the back of the camera. Nothing that would be a show stopper, I just can't believe Canon would miss something like that. (Which is why I use Nikon DSLR's. :)  That was in jest for those of you Nikon haters.)
ISO greater than 200 is pointless as photos will be overcome by noise. If all you plan to do is have people hold still while you take a picture from less than seven feet, then you'll be fine. If you are trying to get action shots indoors, forget about it.This camera will gobble batteries faster than a pig runs to slops. You'll be lucky to get fifty pictures out of a new set of alkaline batteries.
Answer: +1 on Ryan's post.I just recently bought this sx110is camera, and when I was shopping for my new digital camera my very first criteria was AA batteries.It goes without saying that having a universally available power suppy while traveling is indispensible.  It's so easy to forget to charge proprietary batteries - and that's if you remembered to bring the charger.Even at home, I never want to have the day come that I want to capture a moment but can't, because I forgot to charge the battery pack.It's true that you'll get more shots per charge on a proprietary battery pack, but when you can get several hundred from a set of AA's, what else do you need?The one downfall of the 2xAA's in this canon is a long flash recharge time (during which you cannot take any pictures, flash or not) - around 5 seconds if you use the highest of 3 flash settings (flash recharge is pretty quick on the medium or low flash settings).  If you're going to be at an engagement where you're going to want quicker turnaround (wedding/whatever) you can always buy Lithium AA's - expensive, but great performance.Also consider that a typical lithium battery pack will only last around 5 years.  It's the nature of lithiums.   Plus, if you care, niMH is better for the environment than lithium...
