The on-off switch is difficult to use. There is no "dial" for switching shooting modes, so it takes extra steps to go through the menu each time. Does take good photos, but the zoom is nothing to write home about.

Bought this exactly to be a point and shoot camera. It sometimes takes great pictures, but most of the time focusing is a problem.
Indoors it is not fast enough to capture the image. It has a delayed response indoors especially trying to use it with the flash.
I can take very nice pictures in daylight or not using flash option.

The quality of the pics are not that good. Also, you cannot zoom in while taking a video...I mean, really?! What's that?! So crappy. It finally died the other day (fell on the floor and the lens detached from the inside) which I am honestly happy. Now I can get something better. Buy at your own risk and know that this is just a delicate camera for occasional photos...

I bought this in hopes to replace my Sony RX100 due to its 10X zoom and touchscreen.  The ZS100 is great during the day with good lighting especially fully zoomed out.  I was taking pics of a cross country meet and was pleasantly surprised that the Auto function did a good job adjusting the shutter, speed/exposure and focus quickly.  It was encouraging because the Sony RX100 required manual changes to do that ahead of time.  Also, the touch continuous autofocus on a subject worked great during tracking.  Unfortunately, it failed all my expectations in low light performance.  I was inside a decently lit basketball gym (night game so no natural light to help) taking picks of the game.  This time the auto function did not work well with the exposure and shutter speed.  Movements were blurry and the focus too noticeablely longer than before.  This was especially bad when zoomed out 4X-10X (since this is past the RX100 optical zoom of 3.6X).  I had to manually adjust most settings and I just couldn't get clear, crisp images.  I had to go past 6400 iso to get good exposure the further I zoomed out so that made things very grainy.  When I did get a good pic, the focus usually seemed soft which is another trade off to the lens that Ive read about. I did take images with the RX100 during the same game and felt the digital zoom actually looked better than the ZS100.  I decided the ZS100 zoom performance was not good enough in low light to replace my RX100 so I returned it.

This camera does indeed take magnificent pictures if you are outdoors or somewhere very brightly lit. Magnificent! But indoors or someplace with medium light, not even low light, MEDIUM LIGHT, it does a general focus rather than picking an object or face and focusing on that. It's weird to explain, but rather than a small green box indicating where the camera is focusing, one big box appears and takes up most of the screen, and there is no way to change it. The general focus means that it doesn't actually focus on anything so nothing looks sharp. At all your family gatherings such as birthdays and holidays, the pictures will be disappointing, even mid-day with all the shades open, the pictures are severely lacking. The zoom was a nice bonus but not needed so I swapped it for Canon SD 940 IS and couldn't be happier. Outdoor pictures are just as good but indoor pictures are far superior.

When pictures turn out good, they turn out really good (great, excellent, so much better than with other digital cameras) with vivid colors and great sharpness.  However, in low light conditions they don't turn out that good.
I bought this camera only for it's great optical zoom which is the greatest advantage of this camera so you can compose what you really want.  8x optical is more than twice as much as what most digital cameras offer and I don't know how those other cameras sell with such a useless zoom (3x optical is nothing!) 3x optical is just ridiculous when 8x is already available.
The autofocus is sometimes very disappointing.  It might let you down when you need it the most.  For example, African Safari, great opportunities missed because the autofocus just took too long or just didn't focus at all!  Very frustrating. Like if you went to Africa every day!
I had the c700 model before this one and I'm not sure if selling it to my brother was a nice thing to do with a brother.  Had the same problems. Big surprise when I found that the C-720 doesn't have sound capability in the video mode. C700 had. Why would Olympus come up with a newer model with more resolution but decrease the zoom to 8x and take out the sound capability?  Go figure!!  Bottom line: if you don't care about having sound on your video clips, don't care missing some once in a lifetime photo opportunities because the autozoom didn't work, then go for it!  But, if you don't mind spending [a more money], maybe the c730 will not have all the flaws of it's predecessors.  However, that's what I thought when I upgraded from the c700 to the c720 so we are back to the beginning and Olympus is unpredictable.  Lets be positive and think that maybe they get it right this time.

Outside it takes brilliant pictures, inside, not that great. Most of the time they come out very pixelated and the flash has a long delay and is blinding for those in the picture. It also drains the batteries (no matter brand or price and forgot it if they are not rechargeable) so fast you can't get through an entire event with it.

It takes sharp clear hi res pictures. But I don't like it when I hold it as there are no holding grip. Secondly, zooming capability is so limited compared to similar size Panasonic DMC-ZS20.

I like it but compared to some of the other cameras out there, it's not the best photo for your value. It is super tiny and better than any point and shoot. But without a super fast zoom lens, I just use my f/2.8 kit prime lens and it works well. No complaints, just buyer's remorse considering the other cameras on the market.

This camera is good for a novice.  Picture clarity was good, although the zoom was painfully slow!  Too slow for me.  Unfortunately, had to return it.

Pros: very good for point and shoot.

Cons: The zoom doesn't work as intended, it makes big noise, so while recording you get even the zoom noise.

I like the zoom, it is useful. It can even take pics of the moon. The bad part it the focus. It is a slow procedure.

This camera works well for an inexpensive camera but does not focus when zoomed in. I purchased it to film my son's football and baseball games so I am zoomed in almost all the time. When zoomed in tightly the picture becomes grainy. So for us, it didn't work out.

I returned the camer and received a prompt refund.

My family bought this camera for me as a gift prior to our family vacation based upon the rave reviews. I loved the display, ease of use, and compact size, but I am not impressed with its performance. The camera takes fairly decent photos if your subjects are in good lighting and are perfectly still, but if there is movement of any kind, the pictures often come out with ghost-like blurring. I tried using the action setting to see if that would help with the blurring, but it did not appear to make any difference. Many of our vacation pictures came out blurred, and I missed a lot of photo opportunities because I could not get the camera to focus in time to get the shot IF it focused at all.

While waiting for our flight in an airport terminal, our sons were sitting on the floor a short distance across from us as they charged their laptop with a wall outlet that they had found. I tried to capture the moment, but no matter how many pictures I took, I could not get the camera to focus even though I tried different settings, flash vs no flash, and distances with the zoom. I don't know if it was because of the lighting in the terminal or the reflection of the shiny polished floor that they were sitting on that was causing the issue. I had the same problem at a family member's home one morning during breakfast. Most of the family was standing around talking, while other family members moved about. Once again, almost all the photos blurred. I'm pretty certain that the camera was having a hard time focusing because of the lighting in that instance. Another time our kids and their cousins were playing in a family member's front yard. The time of day was perfect; it was early evening with lots of natural indirect light. But every single photo blurred except the ones that I took of people that were standing perfectly still. Some of the photos came out with one person focused, while another right next to them looked ghost-like because they were in motion. For someone like me who likes to catch natural photos of people and life in action, I would not recommend this camera.

It doesn't take pictures ...the megapixels suck...its talks back to me and can't seem to find where in the menu to shut it up....I brought it with me on location for an engagement shoot, and the clients complained that it looks to "Fisher-Pricey"....BAHHH ....what do they know about cameras.....Sod decided to put it in my little nephew's first Easter basket and he loved it! ;) Looking to turn him into a pro Photographer as well.

Hmm, I am really wondering how this gets such a good rating.  It was easy to set up and attach, points for that.  But the pictures are far from tack sharp.  I wish I had saved the money and put it towards a good zoom lens for my SLR.  I'd like to see some photos by the folks who gave this 4 or 5 stars.  And I've got good binoculars, Nikon Monarchs.  I'd day save your money.

Very good zoom camera. Takes great pictures, easy to operate, very good image stabilization at high zoom.
Does ok in low light situations (for a non "SLR" like camera). And yes - just like the other users mentioned - it has kind of a cheap feel - however the photos you get from the camera make you forget about it.
