Olympus 4/3 lens on BMPCC

I just received a 4/3 to M43 adapter in the mail.
$40-ish on ebay:

I have an old Olympus DSLR, the E-500 which came with 2 kit lenses.

I took a punt on this adapter and as soon as it arrived I tried the 2 lenses on the Pocket.

One worked, one didn't.
I can't believe it.
An 8 year old lens works on the Pocket with auto-focus and auto-aperture.
I'm not used to auto functions on a video camera but I can see it has it's uses.

I've just successfully adapted a good quality B4 ENG zoom to run on the Pocket as well.

I love this camera.

That second setup is great - except you have to know where to look or you won't find the camera...

Are you making fun of my camera?
yes, it looks a bit ridiculous.
However, the images are better than off the F900 this lens was used on.

I also have used 4/3rds lens, Pany/Leica 14-50 zoom, and all features work with Pocket cam. However, auto focus did not work on AF100.

Hello Pablito,

A couple of questions if that's OK.

Does the B4 zoom cover the Black Magic Pocket Camera sensor without vignetting?

And which one is it?

Thanks in advance.

Does the B4 zoom cover the Black Magic Pocket Camera sensor without vignetting?

The lens has a built in doubler, or telephoto extender which can be switched in.
Without the doubler it vignettes from 8-60mm, but is ok from there to 130mm.
With the doubler, there is no vignetting but it loses 2 stops and is a bit softer.
This would apply to any tele extender.
As it is quite a fast lens, the loss of 2 stops is not drastic.
The doubler brings it from f1:1.8 to f1:4
There is still usable focal distance without the doubler from 60-130mm, and it's sharper and faster.

I paid AU$2500 for it 2 years ago and it was about $12,000 new I believe.
It has internal focus, is parfocal and has a fancy digital servo that makes zoom and focus just beautiful to use.
I sold the digital zoom and focus controllers and was trying to sell the lens but couldn't even get a $1000 for it so I decided to keep it to use it with the BMPCC.

My initial tests seem to show it is quite sharp and usable.
It seems to focus best at around f5.6 so only works in a well lit scene.

And which one is it?

It is a Canon J16ax8BIASD

Canon "J" lenses are 2/3", with a "V" they are 1". Get the latter ones!

The V prefix are usually C Mount and not B4.
