EX3, a 10.000 euro camera with great image quality but the most problems i ever experience in 20 years.
1) Back Focus problem, i think you know about it...
2) one of the ND filter unstuck and droped inside the camera.
3) the hand strap that holds the camera to you hand broke from one side (plastic), see in photo.
i need to mention that i love my equipment and i am very careful with them.
Never experience so many serious problems with other cameras half price of ex3 so sad.
IN THIS VIDEO THE AUTO FOCUS IS ON.
