great to see rolling shutter is minimal!

Not sure where 1.3 came from. The BMPCC sensor diagonal is 14.32 mm. That's 1/1.5 of the GH2's 21.41 mm, or 1/1.38 of the GH3's 19.83 mm 16:9 sensor area.

Personally, I find that when dealing with multiple formats, using crop factors to convert focal lengths to a reference format is more trouble than it's worth. And since a lot of cameras these days have built-in crop modes, it's like a switchable multi-format camera, so we can often be dealing with multiple formats. I just take the ratio of the focal length to the format size. E.g., 20 mm lens on the GH2's 21.5 mm is close to 1:1 - a normal lens. A 14 mm lens on a 21.41 mm sensor is 0.65: a wide lens. An 8 mm lens on 1080 ETC's 8.3 mm is normal. 15 or 16 mm on BMPCC's 14.3 mm is normal. Etc., etc.

This is probably going to sound like a stupid question, but the Prores bitrate of 220Mbps, is that referring to megabytes or megabits? Does this mean I could use my Sandisk 32GB Extreme Pro 95MB or do I need something faster?

RE: CA and Distortion correction --

CA, at the very least, you should not have to worry about if you're using Resolve. Give me a bit here to finish exporting some more of my feature film, then I'll upload a quick CA removal test with motion in regards to the 25/0.95 SLR Magic wide open.

Now that I've learned how to do this, and it really does take but a few seconds to fix, CA is no longer an issue for me on any lens, which is a pretty huge thing considering it can be a bit discouraging.

Will throw up a link in a bit here.

Why does this thread still read 2K?

@Vitaliy_Kiselev it seems to me the issue with RED / Sony over RAW isn't that RED are claiming they do compressed RAW, but the fact that they to a YUV transform of the RBG sensor data and compress and process the Y separately (from what I've read of the patent).

That's not what would be happening in this implementation of compressed DNG, which is already in the spec.

Personally i'm not going to worry about getting ultra wide on the BMPC when I get it. I have other cameras to pull a landscape with. In fact I might just use the GoPro Hero3 for this purpose. It's not like most of the shots i'd be likely to do in a narrative are going to be needing an ultra wide angle. With what is currently available for m4/3 I can get plenty wide for most of the scenes i'd be looking to shoot and then I might just go Anamorphic anyway so there are options.

@John_Farragut do you think some of those lenses will support image stabilisation? I think that working IS is important for such a small and light camera.

As already mentioned, you can always check how much lenses will distort at Photozone, they compare the uncorrected frames for all µFT lenses. But I wouldn't worry too much about correction issues, now that Resolve 10 is supporting Plug-Ins. I'm sure what we need will be ported soon.

@kodakmoment: True, it will rocket now. Last year I bought a 12, 16 and 25 and passed on the 9.5, since it would vignette massively on the GH-2. Stupid me! But I got a Mutar…

Bmpcc shoot raw and you grade the footage in post and encode into 8bit codec

Canon dslr uses picture styles and converts raw into 8 bit in camera, so custom picture styles can be a way to make canon cameras behaves as a bmpcc...

@_gl Thx I hadnt considered jello as an issue.

-I am REALLY confused about the 1.3x crop factor here can someone please simplify if I am using my 25mm summilux on this is it WIDER than on a gh2?....Was he meaning to say 3.1x?.... I dont understand how a smaller sensor means the camera has a lower crop factor than Gh2? The only thing I want to know is HOW WIDE will my M43 lenses be as compared to Gh2?

@shian So my lenses will be wider than when they are on my GH2?
