Thanks for the input Pete and Scott.
Yeah, the lens adaptor would be a 'down the line' kind of thing. I'm not completely sold on it (mostly because of the cost), but it'll be hard to judge till I actually start shooting and seeing what I need.
For now, I don't think I'll use all of my $2500 budget. I'll just save it now, so in a couple years or so I can talk the wife into letting me get something higher end. I will probably buy some lights. Can you guys suggest any less expensive lighting equipment to get started?
Also, I'm looking into building a DIY steadicam since I can't justify buying a Merlin just yet.
And for sure...for the time being I will immerse myself into learning the fundamentals. (I wouldn't know where to start trying to use filters like a polarizer and ND neutral density grad filter Pete)
