The camera comes with an impressive amount of accessories and has some attractive frame rates for slow and fast motion, which is why it's so frustrating that the picture quality is so bad.
*** Fixed focus lens ***
With a 175 ° -Fischaugenobjektiv you can get a very wide view of a scene, which makes sense for an action camera. Theoretically it makes for an action camera also makes sense to have a lens that can image close to and further away Situated objects simultaneously sharp. This reduces problems with focusing on fast-moving objects. The disadvantage is that the sharpness of the lens from distances of one meter, although satisfactory, it is not good if objects less than one meter away. Unfortunately, taking this a bit to enjoy it as fisheye lenses the size of nearby objects distort: the huge nose of a friend stands out from the image and is smaller again when he turns his head, but the subject is the Rollei always blurred. When shooting with the Rollei people, it is advisable to continue to be removed so that they are sharp, and then the angle of the lens 'wide' to 'medium' or 'close' to make, so they do not in the picture seem small.
***IMAGE QUALITY***
Even under ideal lighting conditions are Rollei Bullet 5S videos very noisy, which is apparently caused by the compression used. If the lighting conditions are less than ideal, the image quality will be even more from, it occurs very strong noise and banding. It really makes no sense to include such images in Full HD resolution.
*** UNDERWATER ***
Underwater photography places high demands on each camera. One of the biggest challenges is the lack of light. Another problem is the turbidity which occurs even in the clearest water and it is very difficult to get enough contrast in the subject - unless the subject is very close to the camera. Since the Rollei has a rather poor performance in low light and near objects can not focus, it is virtually useless for use underwater. That's really a shame, because the underwater housing is very robust and very well sealed.
*** Other disadvantages ***
The camera will beep at each picture and when starting and stopping a video recording. It makes sense to have auditory indicators that inform the user that the recording has started, for example, when the camera is attached to the helmet, where you can not see. However, it is very annoying,
To hear a tone at each picture, especially when these beeps can not be turned off using the snapshot feature and. Even more annoying sounds that accompany each button, but fortunately you can at least stop them.
The camera has a digital (rather than optical) image stabilization and a digital (instead of an optical) zoom.
There is no manual control for the exposure.
You need a screwdriver to open the remote control to change the battery.
***SUMMARY***
I was really looking forward to this camera and how to use underwater and for slow motion video, but the image quality is extremely disappointing. I can not recommend a purchase unfortunately.
