I have this camera. It transitions from sun to shade well, the quality is quite good for me, but as this is my 1st proper camera that isn't one of the little 'Spy' camera's that Mastamax mentions in the previous post, I cannot really make a quality comparison. I like the way it is fully self contained, but I did have a problem with the SD cards. I bought 3 X 32 Gig SD cards from China on e-bay, and while they all worked at home before my trip, they didn't handle the vibration once mounted to the bike proper. They would make the camera 'lock up', and the only way to stop the recording was to turn off the camera. That then wiped the movie from the SD card. The 32 Gig SD card that came with the camera worked fine, I guess that what I am trying to say is use smaller capacity 'proper' SD cards.
