ok, here's a quick and dirty focus test of the B&H Angenieux RF 10mm f1.8 using a Metabones C-M43 adapter.
 
The first shot is as you'd expect to use the adapter, with the lens on fairly tight.
Not going to win any awards with this one...
 
Next, I unscrewed the lens a bit.
Getting better...
 
Next, I stopped down to f5.6 with the lens still loose.
Now we're getting somewhere...
 
Last, f8 still loose
Best of all I think. 
Even with a bit of vignetting at the corners, I like this lens.
I prefer 2.35 anyway...
 
As I say, quick and dirty test. I'll try to get something more photogenic during the week.
 
Right, I'm off to make some shims...

My Metabones C-M43 adapter arrived today but I've only had 20 minutes to try it out.

What I did discover with my Angenieux 10mm is that if I tighten the lens into place I can't achieve good focus.
However, if I unscrew the lens on the adapter, about 1/6th of a turn, it pops into focus nicely.

Basically I will have to add a shim between the lens and the C adapter. Not too difficult.

Try it on yours, It may work. Be careful not to loosen it too much, as I said, I only undid mine about 30 degrees - very carefuly!

Also, to get the best out of the 10mm you'll need to stop down to it's 'sweet spot' which will be around f5.6

I'll upload pix when I get a chance. (Which means when I've figured out how...)

Eagerly awaiting your Pocket Cinema Camera? You already have a micro for thirds camera and some C-mount lenses? Want to know if they will cover the sensor of the Pocket? Lets find out! I hope you will add your results, so we can make this list growing.
 
I will only add lenses to the lists when you have proof, in other words: images.
 
How?

Because we know the active sensor area of the BMPCC measures 12,48 x 7,02 mm, it is fairly easy to check if our C-mount lenses will cover the full sensor. Calculate this by taking a picture with a lens on your micro four thirds camera, and crop out the image area of theBMPCC.
 


In Photoshop:
Open the image. Go to Edit > Image Size, uncheck resample image. Change Image width to 19 centimeters, press ok Go to Image > Canvas Size, change dimensions to 12,48 x 7,02cm, press OK to crop the image to BMPCC size. Resize to 1920x1080 pixels Post your results! Note: If you shoot on the GH3 or other MFT camera's, the sensor size is 17 x 13mm, so change the width in step 3 to 17 cm!

To lazy to do it yourself or you can't work it out? Upload the full resolution files and I'll do it.

List terms explained:

Yes = covers the full sensor of the Blackmagic Pocket Cinema Camera
No = doesn't cover the sensor
Needs modification = Doesn't fit on C-mount to M43-adapter without modifications
Equivalent = The focal length and depth equivalent on a fullframe camera (5D Mark III for example)

Taylor Hobson Serital 1" f1.9 (25mm)
Another old newsreel lens. Nabbed this one off ebay for £40 ($60) Bargain!   Focused at infinity at f1.9 and then f5.6 the Red box is the BM Pocket Cinema Camera crop  
Minimum focusing distance at f1.9 and f5.6
 
I'm happy I got a bargain with this one. Not good wide open, but then most lens' aren't.
Stop it down a bit and it gets really nice.
 
Should cover the PCC sensor with ease.
 
P.S. Don't judge these shots on their artistic merit, I just shoved the camera out the backdoor...

Taylor Hobson 1" f1.9 (25mm)
I think this is another Serital but it's not marked so I can't be sure. It looks very similar to the Serital but it's slightly longer and is slightly bigger in diameter. Focused at infinity at f1.9 and then f5.6  
Minimum focusing distance at f1.9 and f5.6
 
Again the Red box is the BM Pocket Cinema Camera crop
 
I chose the same subject matter for all three lens' in order that people looking
to get any of these can have some form of comparison.
Although hardly a scientific one.
 
I think I'll dig out my old Arri Schneiders and my Cooke tomorrow...

Taylor Hobson Super Comat 1" f1.9 (25mm)
 
It's an old newsreel lens I picked up when I bought a Filmo a few years ago.
Mines not great and it's tiny, which makes it a pig to use, but it works
(a minor miracle considering it's easily 60 years old)
Focused at infinity at f1.9 and then f5.6 the Red box is the BM Pocket Cinema Camera crop
 
 
Minimum focusing distance at f1.9 and f5.6
 
I'm using a red box rather than the canvas resize method because I find it easier
to judge the falloff on these old lens'.
 
My file naming has gone a bit pear shaped. Ignore the 'mm' after the f stop value in the picture titles

I know this is a C mount compatability list but is anyone interested in other cine lens options?

I've got some old Arri ST lenses and a nice new adapter from Metabones that I'll be trying in the next few days.

Should I post results here or keep this one to C mount lenses?

I guess what I'm getting at is that for wide angle lens' adapter manufacturing quality does start to matter.

With a small sensor wide lens' are very intolerant of back focus errors.
The B&H Angenieux 10mm f1.8 is a fantastic lens. They cost a fortune when they were new.
The lack of focus wide open in the test shot back in post #88 could well be down to incorrect flange depth.
I put more faith in Pierre Angenieux than I do in a $10 C mount adapter!

I don't have a C to M43 to test this but I do have a cheapo ebay C to Nikon 1 adapter for my J1.
I'll put my Ang 10mm on my J1 and check it against a focus chart and see.

Hi All, really useful thread.

Just waiting on some C mount adapters to arrive and I will add my lenses results to the list.

One thing I don't think has been fully addressed is the quality and accuracy of the adapters.
In order to achieve correct flange depth they have to be accurate to at least 1/100th of a millimeter ( possibly even 1/1000th )
I've also noticed on my C to Nikon 1 adapter is off centre. Vignetting is always greater in the top corners rather than the bottom, suggesting the C mount hole is above centre. (Could also be that the sensor is mis aligned, but i'm more inclined to trust Nikon than the adapter)

Given that most adapters are really cheap it may be worth us sharing info on the adapters we are using.
It won't have much effect on sensor coverage but will have a big effect on ability to focus, barrel distance marks and overall focus issues.

I have a couple cheapies on order from Ebay but they may well come from the same workshop in China so may be identical. We'll see...
I also have the much more expensive Metabones adapter on it's way which seems to have a very wide base for the lens. Again we'll see...


Julian, wouldn't you be better off modifying an adapter rather than your lens?
Cheaper to replace an adapter than a lens?
