The processing is wertig, the weatherproof awesome, the unit is afloat, responds without delay and it makes a whole lot of fun.
What prompted me to enter the unit back:
The form factor, ie the absolute dimensions are too big for me in practice.
The unequal gaps I can not tolerate in this price range. I find it extremely weak that Sony does not manage to make the production process so that the discs are exactly glued. Much of the competition, the better.
The 4K video mode seems to be implemented somewhat undercooked. There are no settings for the autofocus system, ie, the camera does what she wants, which is not always the desired result. Touch Focus can be adjusted in Full HD mode in 4K can not do that unfortunately. Add to this the already known fact that the camera in 4K mode is switched off after less than two minutes of recording due to overheating and the Außemtemperaturen to 20 ° C. Such deficits must either be mentioned in the specifications or is defective. Personally, I do not think Sony can solve the problem with a software update and tap a problem thermal design. For many applications, this time limit may not of concern, I was disturbed it regularly.
