Battery life not impressive. And for a "rugged" camera, the body scratched VERY easily. I had an old Canon D10 that finally stopped working after many many years of hard use, most of the time bouncing around the cockpit and it still looks great. After one trip out the TG3 had paint scratched off all over the place, and it wasn't a particularly rough use day.
This camera ruined my vacation pics. I'll be avoiding Olympus in the future.
The biggest feature is something that gets overlooked on compact cameras, the Lens, and this has a good one. F2.0 which means the camera captures more light in darker settings and that also helps when underwater, inside dark rooms and taking multiple shots at once, rapid fire style from 5fps to 60fps!!! (fps = frames per second) The fps depends on the size of the files you are capturing. I got some amazing pics of my wife getting ice water dumped on her for the ALS challenge which I took at 5 pictures a second at 16M with great high quality which I blew up to 24"x36" with great results!
The Micro setting is remarkable! As I mentioned above I used that setting to take some great pics at about 30' of all sorts of marine life which was really cool and most turned out great. You can literally set the camera 1/4" from your subject and take a picture with great detail, just mind the light, I used an underwater light for most of the shots I took to get more detail.
I could go on and on about this camera (and I am) but for a camera guy I don't think there is anything even close to this camera unless you take a DSLR made for underwater conditions which is thousands of dollars more and you can't drop those!
Now for the part my wife loves, you can control almost everything on this camera from your smart phone and then import the pictures to your phone! Yes you use your phone to snap pictures, program your settings and all off of a WiFi connection in the camera! Even I think this is supper cool and I have used it more than once to get in the picture without having to run into the shot within the 8-12 seconds timer counting down! Just use the phone to remotely take the picture while you stay put, and you can even see the image the camera sees on your phone before you take the picture, too cool!
There is sooooo much more to this camera that I haven't even touched on so go check out the Olympus site and do your own research to find out all the rest of the stuff this camera can do including taking video!
OK ready for the negatives I have found? The dials, levers, buttons and catches (battery compartment) are all small and can not be operated by big hands with gloves. There isn't a fix for it but just be aware that the buttons are all small. The telephoto is only 4x so it's not able to zoom in close on anything because the lens is fixed in the body case but some of that is solved by moving closer to your subject or cropping your shot later which only helps to a point before you start losing quality.
I am a moderate to good photographer and have been taking pictures for over 35 years with all types of cameras so I do think I know a good picture when I see it. I have taken some great pics with cheap cameras so its not only the camera but the photographers ability that counts, but it you have some skills or are willing to learn this is a fantastic all around tough camera. I am very happy with my Olympus TG3
