Sony Handycam Users Manual NEW!
In addition to the new zoom function, the NEX-VG30 includes new picture effects, a better viewfinder, and a multi-interface shoe that fits a wider array of accessories than the NEX-VG20. The hot shoe mount will support a new XLR mic kit that will allow the NEX-VG30 (or the NEX-VG900) to record balanced audio via XLR inputs at an additional cost. Sony also made a few changes with regard to button placement and body design that should give users quicker access to manual exposure controls.
