A:AnswerThe Canon 710 has a slightly wider aperture f/3.2 vs f/3.3; the PowerShot SX720 HS has more zoom 40x vs 30x; better wide angle 24 mm vs 25 mm and slightly longer battery life 250 shots vs 230 shots.
A:AnswerYea. I'm returning the camera because of this issue. Sometimes it will never focus, the little square will keep bouncing around and I can't get it to bracket around the subject I want to photograph. This is the Canon SX 720.
A:AnswerThe camera can be connected to a Windows computer. The files from the camera will show up as a drive so pictures and videos can be copied to the computer.
A:AnswerYou can use both option like USB and wireless to transfer your images to PC or any smart phone. For wireless, you have to be on a same wireless network to connect your camera with a PC. For USB, just download its original application and connect the camera via USB cable.
A:AnswerDepending on how new your battery is. I took mine to California and took pictures and video off and on all day starting with a full charge. Even took video up Hwy 1 in Malibu for 8 miles while stopping off to take pics of the ocean. I can't say an exact hour but can approximate I had it going 4 hrs total with no problems and battery still left. Note this was a new battery not one used for a year plus. All batteries lose life over time. I have purchased a back up battery since now that I have more use on mine. But still no problems - satisfied with the life of use.
A:AnswerYeah -- I believe it is optical. The image stabilization works well, even at high zoom. It is most affective when the subject has a particular feature, like the eyes on a face, to focus on.
A:AnswerThe video audio is terrible. The microphones point straight up so they aren't bad if the one holding the camera does all the talking. I record audio with the Tascam DR-05 and then replace the video audio in post-production.
A:AnswerThis may be late but for others out there it works okay. My dad enjoys taking photos of the Northern Lights as well. From what he tells me is you need a camera with long exposure and the larger the MP the better. To take good quality photos of the Northern Lights it would be better to have a more professional camera, aka Nikon, or else the colors will not be nearly as bright as you see them.
