The reason for this decision is the brilliant image stabilizer. What I film? Mainly my little daughter. I've never had a camera stabilizer which works so awesome, even if I run my daughter behind her. The picture quality is class. At least during the day and that's where it differs significantly from the PJ650 is significantly better in the dark and has additionally installed a projector. The projector I'd find true practical and the higher light intensity would have been nice, but there is still a "small" difference in price, so I have decided consciously for the CX410.
The operation is practically on the touch screen. The sound quality was very good inside, you just have to be careful that you do not get too sliding around with your fingers on the camera, which transfers easily to the camera. Sound recordings so is outside in the wind one thing. I had expected here but not too much, because there is a problem with almost any built-in microphone here. Therefore, I had bought into the microphone ECM XYST1M that fits on the accessory shoe and is supplied with "pompom" and therefore protects very well against wind and is also "rubberized" or uncoupled to camera noise not to transfer.
Conclusion:
Completely satisfied, doing what I expected, who expected more have to pay more and take the larger model PJ650.
