What do the XH cameras have that the XL H1 doesn ?
A The XH series camcorders include a few features not found on the XL H1, such as a new, very fast autofocus technology called “Instant AF” which utilizes a passive IR sensor. On the XH G1, the HD and SD output over SDI embeds audio and Time Code along with video, whereas SDI output is video only (without audio or Time Code) on the XL H1. The XH series camcorder lenses have manual iris control rings and a wider field of view compared to the XL H1. Some of their custom preset image controls have an adjustment range of +50 to -50 (compared to +9 to -9 on the XL H1). Master RGB adjustment at the CCD level is 140% greater than that of the XL H1. There is a new Sky Detail Control feature, similar to Skin Detail Control, and a separate six-axis color correction feature. The camera menu displays are customizable, and user-programmable function buttons which can be set up as desired, as an example for “shockless” adjustment of white balance, gain, or exposure.
