Davide, the point of forums is to discuss the realms of possibilities and nuances that may not be considered. Even Ryan started thinking about the Ultra Prime 6mm as a possibility and I'm sure if he saw the Century 6mm with adapter, he'll probably be convinced. Now is it practical to get T stop, focus gears etc on a small housing? Most probably not, but hey neither is getting a RAW or even a Pro Res camera, even @ under $1k.
Going back to the 7-14 Lumix, I remembered it showed low distortion because it is software corrected in stills. Were your tests using still software that is corrected or video that's uncorrected? My notes say CA but also barrel distortion @ 7-10mm.
The point of forums should be to let users to take an informed decision. The paradox on the interweb is that it's full of people speaking of what sex an angel is. There's space for everything of course, but when the noise increase (nuances that may not be considered) forums like this loose sense.
It happens dozen of times. Every time you google for buying a smartphone, a camera, a car... you will find someone complaining about the most exotic nuances.
MFT is probably the most versatile mount/size as today. It's not just chance that it's the second BM camera designed with this mount. You can mount nearly everything. I used for fun on my GH2 the most exotic lenses with cheap adapters.
The problem is that 90% of camera manufacturers and users don't even suspect that you can bring a camera underwater. Hence 90% of housings have ports for standard or most common lenses. You have some exception like the latest Red camera housings (but, again, we are speaking of a complete setup in excess of 30K euro).
My bet on upcoming BMPCC housings is that you will have something like Nauticam mirrorless line: a simple yet bulletproof design with standard acrylic ports for current m43 lenses. They already have everything ready. Hence forget about Tokina 11-16 or other wonderful cinema lenses. Nobody will design a custom ring adapter for manual focus or zoom for a 995$ camera.... We will see. Of course I hope to loose my bet.
BTW 7-14mm is one of the best wide angle lens out there. Tack sharp with minimum distortion and CA in real word use. Just search for it on Vimeo. I forgot that here we are filming pool tiles alll the day
Distortion is corrected in camera and it works perfectly with video too, also on Olympus bodies.
AFAIK the BMPCC has an active MFT mount so it should work. Actually a lot of people have a lot of questions on "active mount" definition.
@Timccr: you have a lot of amazing spots just near you. If you are a wreck lover i suggest to not miss the VALFIORITA near Messina: better than the THISTLEGORM.
I know that wide angle shots will likey be a problem with the BMPCC crop factor but again, sadly nobody cares fo underwater filming while designing a camera
I hope to see some BMPCC sample with the 7-14mm soon. This is what you can expect from the 7-14 on MFT mount:
