I was initially ecstatic about interchangeable lenses...until I saw my options at the moment (like I can afford anything else). You can toss on any $10k Fujinon lenses you have sitting around, or the first wave of ghetto rig prime lens mount adapters are rolling out...offering a minimum default of 7x optical zoom due to an optics relationship problem. Does the wide get wide enough, I´d say not particularly for my taste. My first buy will be a .66 wide angle the second it gets worked out by the potential manufacturers. Sony, in all its ¨messin with you¨glory, decided to short us a few mm depth on the 72mm lens mount...hence, all Z1 screw on adapters are useless (even the ones listed on the B&H add-ons drop down menu) and manufacturers need to commit and produce Z7 only group (still holding my breath).
I primarily went Z7 because of cost point, including CF cards. As a recent MA in Documentary Filmmaking grad...$$$ was the defining factor. Mike, if you are gunna go big and do ex-1 (SxS card workflow only), why mess around...grab the EX-3! You can see an awsome first look video review on Philip Bloom´s blog (if you don´t know the brother, check out his videos...sick!). Since the review he has been crying about missing his EX-1, but whatever (you´ll have to read what all thats about).
By the way...your IMDB credit listing is retarded (as in amazing). REEEEESPECT!
