What is clear is that is for 100, such a small image sensor and a lens behind an additional covering, you can not expect photos that produce quality cameras and anyone who does not really need the 'underwater capability ", I recommend another camera.
Basic suitability for underwater use:
Here I was very pleasantly surprised, because I took the camera after purchasing it to Egypt, where I photographed extensively water. Lt. Manufacturer keeps the camera 1h 10m and a maximum water depth and I want no one to motivate them to exceed these limits, in my use but was also two hours snorkeling with many photos in 2-5m depth no problem.
The important thing is certainly to make sure that the the battery compartment is closed and clean any debris etc. sit on the seals. Also, I have the camera thoroughly washed after use in salt water and dried gently and then let it dry completely. To the buttons unfortunately have relatively large gaps in which also like to settle grains of sand. Here is the supplied brush of immense help. While on vacation I have the camera actually loaded every night and thus the battery compartment so 6 x open is never penetrated when properly handle water and I would give 5 points.
The images below the surface (ie, up to about 50cm depth) are in the underwater mode when clear water very nice and hardly need to be reworked, you go deeper, or has low light, of course, suggests the absorption of water too extreme and the images get a strong blue / cyan engraving and colors suffer with suitable post but I could get good results relatively easily even in such pictures, in order to restore the colors. IAR, it is sufficient to reinforce the contrasts of each RGB color curves. (Good instructions can be found if you search for DEHAZE tutorial).
During my missions, the flash has unfortunately proven to be disruptive, less than the lightning on the fact that this highlights the extremely small particles suspended in the water and so images are created that one of photos with flash snowfall knows.
Also positive the great and good (even underwater) is recognizable display
Point deduction is available for the following disadvantages:
the camera is of course not very bright and the optical focus relatively slow. Fast Focusing is therefore not possible so that you do not get good / sharp pictures in many situations and with me about 50% of the images was committee.
Another negative point is the fact that the underwater mode does not work particularly well. I would have liked a more suitable color matching here by the camera so as not to have to put yourself so much in the post.
The video feature is great in itself, to me, however, was not entirely clear until the very end how the camera focuses here, so that when the video and some of it was available to the Committee and the underwater mode showed no effect, the videos are therefore generally relatively Cyan fusty. In addition, the video button is very large and I have the video recording mode often accidentally activated.
Given the price of this camera, its basically relatively good durability, and the results I am actually very happy with the purchase and can recommend them for use when snorkeling very.
