How does the D800(E) video compare? I have not shot any video yet with mine.
Since the D800 does the ever other line interpreting in LV mode, wonder if Sony sensor thing?
Thought I'd chime in on this one since I spent some brief time with the a99. The D800's video capabilities easily best the ones of the a99. The ability to zoom in to check critical focus in live view is one of the main advantages of the D800. And like one poster here mentioned, the a99's video was definitely soft in comparison to footage I captured on the D800. The D800 was sharper with better color reproduction for video in my experience. Another annoyances is not being able to press the record button and enter right into video mode that allows you to change your exposure settings. Instead you have to switch the dial to movie mode and then you can change your settings. It also works the same way with manual and autofocus, but even more quirky. To switch to manual focus, you need to be in a still shooting mode, change to manual/auto focus, then switch back to movie mode. It's the most ridiculous implementation of video I've seen in a DSLR. The D800 and 5D Mark III are much much better options for shooting video.
I ended up not liking the a99 as a camera at all, although I had high hopes for it. I love the look and feel of it and I figured it would be the perfect blend for photos and stills. However, I must admit the 5D Mark III takes the crown there. It's the most balanced camera out of the a99 and D800. Shooting stills is smooth as butter and focusing is wonderful (compared to the D800) and switching to shooting video is seamless (compared to the a99). And the image quality is great as well, but that's a given. Again, all my opinion, but I thought this may help you make a decision.
