Unfortunately necessary 1

I have the Sony Action Cam bought me as a cheaper alternative to GoPro3 with unacceptable for me less features because I was convinced of the form factor and sufficient for me functions. Since I almost exclusively want to use under water the Cam, I drove immediately after purchase at a river near to the recording quality before the summer test. Even locally I transferred the video via WiFi on your smartphone and unfortunately had to find a penetrating blur. Home on the Full HD TV, a small disaster. Constantly one waits watching the video that the autofocus focuses, but unfortunately it does not happen, but the little blur remains permanently exist.

Then I searched for Underwater Accessories and came across the Sony AKA-RD1 spare covers for Action Cam Kit. Well, I think the price before much too high, but it occurs fortunately a significant improvement in recording quality, color saturation and sharpness, which has soothed me something. I want to say in any case clear that in my view underwater without needing a flat lense cover AKA RD1a (straight wheel) are completely useless. A trip to the Red Sea or in the Pacific would be a cinematic disaster! There are at the relevant video platforms comparative video, which I can only recommend and show why you can not get around it.

That was it but also already! Unfortunately, I have the flat lense edge with darker environments, a small mirror, which is permanently on retest at the same place. Since it was very cloudy and dark, I still hope that now the holiday reflections disappear in abundant sunshine. All in all, unfortunately, a must for underwater with a few limitations.
