I am very happy with my HD3 as I have been with my HD2. No problems whatsoever. Since I have HD2 bacpacs I can use these with both cameras and battery bacpac for HD2 provides longer shoot time due to larger battery. I one of these who wanted exposure lock at the first frame. When doing time lapse of cloudy sky there is no other way avoid constant washout of blue sky or clouds. This feature is absolute must for me and I am very happy that HD3 has it. But exposure lock option for video would be what I am looking forward to as well.
