Sunglasses: The Rollei is yes with transparent and tinted lenses, which you just often requires the sunscreen to go skiing. I would never rely on a pair of sunglasses without UV shielding tested. In this way you can make wonderful eyes broken, and it's not worth it.
Optics: purpose incorporation into the spectacle frame, the camera is reduced to a minimum size. This need not be bad, but good optical elements are more expensive, the more they are miniaturized. Otherwise you have to make any concessions regarding the recording quality, and so it is here. Not that the recordings would be very bad, but the color fidelity and light sensitivity fall over a larger model such as the GoPro significantly. Now Rollei is anyway not for high-class cameras known we have a Rollei model as entry-level camera for our son, but it's okay if a sufficient but that as an adult, you have to think.
Sound: recording in stereo, but only one microphone What is this? For Sale stupid I can myself. Okay, one understands anyway only recordings that were made while standing, otherwise the slipstream is rushing everything.
Parameter settings: Out of sheer smallness is in the POV of course no room for any adjustment, since only remains on and off. One can things like sensitivity or white balance set by connecting the glasses via USB to a PC or laptop and you of course on the ski slopes or in other sports wherever you go. So no, that is not thought out.
"What you get is what you see: This is the big difference between this eyewear and Action Cams that are being worn on the chest. The camera sees exactly what your carrier looks at one hand nice, but is also on the other hand, that it has never been a continuous perspective when taking a ski, bicycle or motorcycle ride (etc.), but it just swung around at every traffic light, side or even Schulterblick ever. Faster head movements are then only desolate scribbling in recording ,
Price: Yes, the Rollei is markedly more favorable than the current, slightly larger Action Cams. This has, as I said, even its base in reductions in the quality. A strong buy recommendation can not submit for this lifestylige camera.
