Question: Does it includes the lithium battery?
Document: Olympus has provided a lithium-ion battery pack that you can connect to a wall charge via USB or a powered USB port for your computer. (Do suggest using the wall charger for the first charge. Thereafter, the USB only charge works great! )Had a small point & shoot Olympus several years ago, and I really liked it. This camera will be my go-to camera for years to come. Or until I need a 72x optical zoom.
I do like my new camera,it operates very good,the only thing is the battery is not holding a full charge,other than that,it was a very good purchase. A battery was only $17.94, so it's still a good deal.
Great value for the money. There are only a couple of drawbacks; one is having to plug the camera in to charge the battery and the other is that it takes a bit of time to focus. (Other reviewers discuss this in more and better detail.) Overall I'm very happy with this camera and would recommend it to friends.
Took it out of the box, put battery in and memory card, pointed and shot my first picture! Easy to use, though I still need to figure out all the settings. Took it to the park today to play with it. Even extending the lens out to max the picture came out amazing.
All of the came out great, very happy with the Olympus. Battery life is quite long. Easy to charge or you can buy another battery for a few bucks and always have a spare. It has a panarama mode that is easy to access, and takes some beautiful shots. Three different photos that are put together to make one.
Love this camera! Great battery, the size is perfect but at times can become a little heavy around the neck. I use the optical zoom often to catch images of animals from afar and the clarity for me is perfect! Would highly recommended this camera for those who are on a budget and want to capture nature photos.
Easy to use, great quality pictures. Still trying to figure out how to use some of the features. I liked the massive zoom option, but have yet to get the results as shown in the description. I bought a spare battery and charger which has worked out well for me. Comfortable to hold. Great features and effects.
Very good travel camera, I also have a older Olympus SP 620 and this unit corrects some issues that I found buggy such as the lens cap falling off and battery cover hard to close ( you charge the battery in this camera) . Like all Olympus SP units this camera seems to be an odd shape but is very practical to hold and lends itself to shoot steady photos.
Was very excited at the thought of a great camera with a great zoom. Read many online reviews before purchasing. Just looking for a good camera for shooting sports, birthdays, etc. Camera had great zoom and neat features, like the 3d pics and the panorama. Loved the camera at first. Then after taking 200 pics in about an hour, camera froze and would not turn off or on or anything. Took battery out to reset.
I hate having to take batteries out of a camera to either replace or recharge. And there's nothing worse than not having enough optical zoom.The Olympus SP-810UZ is awesome! It has 36x optical zoom which is double what I had before. But the operation of the camera? It's smooth, simple, point - autofocus - shoot. I never realized how much better my photos would be with 36x optical zoom - it's amazing.The second best thing about the Olympus camera is the battery pack.
Answer: Absolutely! That was one the key selling points for me...after the 36x Optical Zoom. After the first charge, you can re-charge the camera right after downloading the photos to your computer, using the same USB cable.
