What camera under $4k is best suited for for interviews and seminar videography. I am getting into two camera shoots and need to look into buying two cameras. Most of my work is taping seminars and corporate/business interviews. Some of the shoots the clients want raw footage as they already have an editor. I currently shoot 1080p but 4k resolution would be nice so it's future proof but not a must. Unlimited time recording is a must. I have used DSLR's so I do own canon and Nikon glass. I am open to either cinema type cameras such as the canon C100 or fixed lens video cameras. I am impressed with the specs on the newly released Panasonic UX90 and UX180. What's your take?
