Hello! From some lists i noticed that sigma 30mm & 60mm DN ART lenses should be compatible with x5. So i bought 30mm and it its only kinda working => AF works but cant change aperture. And if i take photo screen goes black and take shot button keeps going around like it is loading. Image doesn't come back without reboot. Video record works without problem. I am using 1.08FW since i had problems with video and 3.11. app.
