Hi,
I've been trying to get sharp/focused footage with my BMPCC this morning and seem to be having a difficult time.
It seems like focus peeking doesn't always work, since even when I've got something as sharp as it can be on the LCD, I don't see any green on it (and yes, peeking is on). Even when I do see the green so that whatever I'm shooting is presumably in focus, when I watch it on my computer it looks... soft. I recall reading that footage may need to/can be sharpened in post when shot in film mode, but the Sharpen effect in After Effects seems to only make it look more pixelated and magnify the noise.
I've tried the Voigtlander 17.5 mm and Panasonic 12-35 mm (with both manual and auto focus) so far and felt the same about footage shot with both lenses, so I figure it's either the camera or me. I'm hoping it's just me. If anyone can give me any tips on how to get things in better focus or otherwise get sharper footage, I'd appreciate it.
Is it possible that it is the camera? Has anyone else had any trouble getting "tack sharp" footage from the BMPCC? I read that footage would be sharper if shot with the BMCC at 2.5k and then downscaled to 1080P. Would it be significantly sharper such that I might want to reconsider going the pocket route after all?
Also, I feel like I need to get my eyes/head checked after watching a panning shot with 23.98 fps with 180 degree shutter speed. It seems like an unnatural blur, almost as if a fast strobe effect has been applied. Is this what everyone is talking about when they recommend using a 172.8 shutter speed? I wasn't sure if I should use 172.8 or 180 since the manual says:
and I am shooting 23.98 fps and not 24p, and I don't know how many hertz power supplies are here in the USA. Can anyone tell me whether I ought to be using 172.8 when shooting at 23.98 in the USA?

While 180 degrees is commonly regarded as a normal shutter angle, you may need to use a Shutter Angle of 172.8 degrees to minimize flickering light when shooting 24p in countries with 50 hertz power supplies. You can use any shutter angle to shoot 24p in countries with 60 hertz power supplies and most people will choose 180 degrees for a normal look.
