Hmmm, I have been watching the releases for some time as I want one camera in particular. The cameras released so far are not the ones I would purchase just yet. Personally I will be waiting for the releases in the second half of the year. I don't have the same problems that Peter has. My camera is working well.
The cameras coming will have higher through puts and larger sensors. My goal is to capture at 2.5x with one sensor and no mosaics.
The version you mention Dave, is a cmos sensor and certainly not my choice of sensor. Every thing sounds good at 90fps but your machine has to be able to guts that down. I can tell you that a fast machine is essential and I mean fast. You will have to buy a gaming fast machine and top of the line to even come close to that frame rate at 4mp.
Pete your machine must be too slow. I bought a 4 grand machine and it cranks out this stuff like no bodies business. 3 minutes to do a 4 gig data file from start to finish. Capture in real time view.
