Question: Why did you choose this camera?
Document: This camera is great. Shutter speed is very quick and you can capture whatever image or moment you want. Many different settings to choose from.
This is a great point and shoot, video camera and also can be used for conventional planned photographs. It is quick between shots or shoot a series from which you can choose the best.
I did not buy this camera from Amazon because of the cost of shipping; but I choose it thanks to Amazon reviews. This camera had the lowest 1 star rating of all other similar products(around 5%) and this is what tipped the scales for me. I have had this camera for a few weeks now and it lives up to its name 'power shot'.
This camera is very nice. Most of my photographs are of my grandchildren and they both participate in sports so the zoom lens comes in very handy. I'm able to get close shots even from across the field.The clarity and color of the images are very good. It has a mind boggling variety of modes to choose from. The separate video button is a big plus.
Did I mention that it weighs only a half a pound and fits in the pocket of my pants and coats? And of course, I always had it with me cause it is so easy to have along. We have all the unexpected shots as well!! I can have it out of my pocket (not in the backpack and have to choose a lens), zoomed and focused in a few seconds while the big camera guys are still getting their bag down!
I bought this camera because of the good reviews. And it is a very nice camera with an excellent zoom for a pocket camera. However, there are two things I don't care for. One, the camera gives you very few shoot modes to choose between. Instead, the camera automatically chooses a mode, and if it isn't the mode you want, there is no way to change it. Two, the camera doesn't have a good macro mode.
If you choose the vivid option be forewarned that your colors will become over saturated. I noticed that if I tried to take a macro picture of a flower while being 2'-5' from the subject that the camera would not focus on it. However if I was standing in my yard and trying to take a picture of a neighbor's flower in their yard (maybe 20') that macro was fine. (My A650 has absolutely no problems doing this).
I can choose shutter speed and aperture, change the white balance, etc.! I also love the quiet setting, it makes no noise or flashes at all, so I can sneak up on the boys during naps and take pictures without waking them!Overall, if you need something easy, with great quality images that allows you to take pictures of a wide range of things, this is the camera for you!! !
I got this camera to take photos of my grandsons' band concerts. I appreciate all the reviewers who led me to choose this camera.It is easy to focus, download to my computer and the software is easy to use. The colors in the viewer when I'm taking the picture are not accurate in the pink/purple range. But the computer image was fine. Taking pictures of butterflies was somewhat frustrating because there is a time lag before I can take another shot.
There are supposed to be over 50 settings for the camera to choose from in AUTO mode; however, I've only seen a few of the icons displaying which setting the camera is using, and each time, it's been incorrect for the scene. I have two girls, ages 3 & 5. I was told by a Canon Rep that this camera would take excellent action shots of the kids. I have yet to get one. The pictures turn out completely distorted and blurry if there is any movement.
Answer: takes great pictures in low light. I find all I need to use is the "auto" mode. Shoots fast as well, no distortion. The 20x zoom is fantastic. I did own a Panasonic Lumix which was 4 years old. I researched Panasonic, Nikon, Fuji and this was the best and I have now owned it for over three months.. Also the battery lasts a long time as well!
