God, I hate to start a 'help me with lens choice' thread but I've reached a limit. I've been shooting with a BMPCC for about three (four?) years.
Background: I'd started with some vintage 16mm glass which was okay but had some issues. Tried an Angenieux 15-150mm that seems softer on the files than it looks on the screen. Tried some Panny's but my camera doesn't seem to want to autofocus. Everything looked a little soft anyway. I'm mainly a still photographer so I've been traveling with 4x5, BMPCC, Hasselblad and a Pentax K1000 (35mm). I tried using a Pentax 35mm zoom (35-70mm) with the BMPCC and turned off focus peaking and I finally started getting images I liked. The problem is that once I started wanting to shoot more cinematically (less of the same kind of stuff that I shoot with my still cameras) that crop factor became a problem. I started to fish about for a vintage (i.e. cheap) solution but decided to look into something better for the camera. As someone pointed out, with the BMPCC you don't need vintage glass filtering for the overly sharpened digital look.
I would characterize my work as documentary in the way that Chris Marker (without the voiceover) is. Landscapes, cityscapes, noirish warehouses and burned out homes. No characters, ambient location sound only.
Question: I see that Tokina makes a 11-16mm cine-zoom that would be pretty wide for me and it's appealing because it's currently on sale. The thing is what do I match that with? I want a manual cine lens and not an AF lens. I can't find a longer zoom that fits my budget but thought perhaps perhaps a Veydra prime to go a little longer perhaps the 25mm. That's under 2k for a start. I figure I can get a longer prime down the road if necessary. I prefer zooms because I hate futzing with extra equipment when I'm out and about because of time constraints but 2-3 lenses doesn't seem bad.
Does that sound reasonable?
