Starting a shoot in June and looking at maybe purchasing an HVX200a. I already have 2 HVX200s and 1 HPX500. For those who have one, I'm wondering what everyone's first impressions of the 200a compared to the 200 are. I guess I'm wondering how much everyone has noticed less noise in the camera, and better low light performance. I may be doing underwater shooting with the camera in lower light area... I guess I just want some real world opinions on how much better the 200a is than the 200... and is it really noticeable? Will it match up better with an HPX2000? or are they just minor tweaks really? Also, is the imager a true 1.1 million pixel imager, and does it make a difference in sharpness?
