I have always thought Sony was flimsy in their build quality but their stuff gets the job done. The FS100 footage and file supposedly is good enough for a big screen (shot w/F3), whereas I hear (but haven't seen) that many who watched the AF100's performance (on screen) in the big comparison study done in the Zacuto documentary was not good. Then I read Barry Green's remarks in another thread about these two cams where he says footage comparisons are not even an issue (sorry to paraphrase him). So, how do you all feel about your purchase? Is the grass greener? Do you have any doubts? Regrets? I am already seeing a thread about cheap plasticy build concerns on the FS100. Thoughts about your AF100 appreciated, good and bad. One last point: I was planning to buy the FS100 and bought the VG10 as a B camera. I have modern Nikon glass (14-24 2.8, 17-55 2.8DX, 60 2.8, 70-200 2.8, 300 2.8). The crop on this is 2x right? That means I'm not going to have much insofar as wide is concerned, at 28mm with the 14 correct? I also read that NDs aren't necessary for DOF and shutter speed control but I am new to this level of video work and could use an explanation/clarification if poss.
