After many months (or years?) of mulling, I decided to buy an XL2. So far, I LOVE it. I had a Fujinon T14 lens I picked up at an auction a couple of years ago, so I immediately made an adapter for it, for times when I want full manual control (most of the time).
The only things I'm not overly fond of are the lack of focus marks on the lens, and the viewfinder magnifier/eye cup, which is just in the way most of the time. I also have a CAPDIV hard drive recorder, which I tried to mount in various places, but it has kind of an awkward form-factor.
So now I'm going to remove the internals of the CAPDIV and make an enclosure that holds both the CAPDIV and a 5.6" monitor in a ore ergonomic design. I will mount that on a tripod plate so that it's held beside the camera where the viewfinder sits, removing the stock viewfinder.
Will post some pix as I move forward with this.
