Hi, now I use a Sony AX100 for my UHD video documentaries around the world (look at my signature). I'd like to buy a videocamera that can give a better image quality, otherwise I will continue to film with Sony AX100. I mean better definition, chromatism, color quality, etc. My budget is around 4000-4500 euro. I think Panasonic HC-X1 is a good videocamera but it has two handicaps for me. It is the bigger and heavier than my Sony AX100. I can think to buy it only if this videocamera gives a real better and clear image quality that my Sony AX100. I watched many videos on the Internet but I can't trust them. I need your suggestions, above all if you use or used both Panasonic HC-X1 vs Sony AX100. Thanks
