First, the autofocus problem: I have tested all lenses including my Canon 50mm 1.8.. Everything brilliantly sharp.
But I am also very pleased overall with the results:
+ Very versatile (swivel monitor, Live View, many AF points, etc.)
+ Very good image quality (s. But below)
+ Very good feel, very good workmanship
+ Wireless control
+ Good videos
but
- Saturation is a bit high. Can be adjusted probably; am still trying out all the possibilities.
Conclusion: For photographers who want to achieve really creative and high-quality recordings, certainly a clear recommendation; for beginners or people who want to take pictures only on vacation, rather too demanding.
