Hi everybody, Bohus here for FotodioxPro.com
and in this video we're going to be showing you one of the most eagerly anticipated Fotodiox products ever,
the B4 Magic lens adapter and the PowerLynx Kit.
These let you attach a B4 motorized zoom lens onto the Black Magic Pocket Cinema Camera.
Now, for those of us who have been shooting video for
a while, the DSLR revolution has been amazing.
You've got all those lens choices, shallow depth of field
effects... but we've been missing an important
thing – the powered zoom! C'mon... the cheapest camcorder has powered zoom, right?
Now, what the pros use is something like this, this is a B4 ENG Broadcast lens.
ENG stand for Electronic News Gathering.
B4 is the name of the mount, that's this bayonet mount on the back here, 
and this lens attaches to a camera with a 2/3” sensor –
which is very similar in size to the sensor inside the
Black Magic Pocket Cinema Camera.
But, I'm getting a little ahead of myself. Let's talk about zoom lenses and why you care about zoom lenses.
Zoom lenses are a powerful visual narrative tool, when you use the zoom sparingly. 
Back when I was a teacher in film school, I had students who would often trombone in and out
of a scene and it looked crazy and gave you vertigo. 
For me, zoom lenses are powerful and I use them mostly for a couple of things:
a subtle zoom in on a poignant moment... nice
and slow way to draw attention to something
important in the frame and it can be very very subtle.
Or you're shooting live events or a documentary, some place where you can't predict the framing, 
or something might change while you're shooting, a zoom lens can help you compensate for that.
Also – and this is a biggie – a zoom lens makes camera placement easier. When you have a non-zooming
prime lens you have to zoom with your feet
which of course means getting physically closer to your subject.
But with a zoom you can just get closer at the push of a button.
A photographer's still zoom isn't perfect
for a couple of reasons. For one those zoom lenses are not
parfocal – which means that the aperture will change during the zoom action, 
so that means that it's gonna flicker in a weird way, you can't really use
that footage in your project. Plus, it's hard
to manually reproduce the smoothness 
of a motorized zoom.
I mean, you can put a follow focus thingy on your zoom lens but you're never gonna get it as smooth as like a nice creeping dramatic zoom.
There are solutions out there. Right now there
are a handful of motorized ENG style zoom
lenses for DSLRs, but they're tremendously expensive, they start at like 10 grand.
There are also lens adapters out there that will
let you mount one of these old beauties onto
your digital video camera, but those are around
a thousand on their own. For most of us, those
solutions are out of reach...
So here at Fotodiox we created the B4 Magic
Lens Adapter. You can get the adapter on its own,
or you can get it as part of the PowerLynx Kit which also includes everything you need to power the
zoom motor. Both the B4 Magic Lens Adapter
and the PowerLynx kit are available starting
today, and I think you're going to happy at the breakthrough prices that we're offering.
Now we've had our beta team testing the B4 Magic
Lens Adapter on projects all around the world,
including broadcast TV. The word came back to us
that the B4 Magic and the PowerLynx Kit are
just what filmmakers and video makers have been waiting for for a long time, and now the
wait is over – both the B4 magic and the
PowerLynx Kit are available starting today.
Here's how we do it. We created this kit expressly
for the Black Magic Pocket Cinema camera,
which is a popular and affordable camera for filmmakers. We are going to support other camera configurations
soon, but for now it's all about the BMPCC.
Then you just have to source a B4 lens. There
are thousands of these in the world, which
is why they're so inexpensive. We can't recommend
any specific models, but look for more recent
premium models. Most of the lenses you're
going to find were for cameras in the Standard
Definition video era, but the higher end lenses
from back then often resolve out to HD resolutions. You just have to shop around a little bit.
Connecting the parts of the system is easy
– just like using any other lens adapter.
Simply mount the B4 magic onto your lens,
and then attach it to your camera. The adapter
has a tripod foot, and the base is Arca-Swiss
compatible for quick release tripod heads.
If you've also got the PowerLynx Kit, connect
your battery pack to the lens using our special
adapter cable, and your lens is now powered up and you are ready to zoom.
If you want a closer look at the specifics
of what comes in the kit, we'll be releasing
an unboxing video tomorrow.
Let's talk about a few more specifics of what
to look for in a lens...
You want a B4 mount. Again, that's just what this bayonet mounting system is called on the back
and make sure that your lens is designed for 2/3” sensor camera. Also look for one that has a 6 pin
or 12 pin cable – this is what we'll use
to power the lens.
You also want to shoot with your lens at f/5.6
and above. These lenses are optimized to work
at 5.6, and our adapter is designed with that in mind. 
Now you may ask "why would they design B4 lenses that way? Why would the focus be
best at 5.6 and above?" Well that is the kind of TV heritage of these lenses talking.
With f/5.6 you get a nice range of depth of field
so actors can be a little flexible in hitting
their marks.The action can be kind of free and loose while you're shooting.
You don't have to worry about hitting a specific mark because there's like a
a razor thin depth of field that you get when you shoot at lower f/stops. That means fewer retakes, focusing is easier.
And on this guy when you dip below
f/5.6, you're going to get soft focus pretty fast, and that's not going to give you the the result that you want.
So, where to find the lens? Well eBay and Craigslist are great choices. Actually, mine came from eBay, You can often find the
lens with the obsolete camera still attached, it's a nice trophy piece fir your shelf,
And another place to check out is the "B4 on M4/3” group on Facebook.
There are a lot
of folks on there who can offer advice on which
lenses to get, and there are frequently second hand deals on there as well.
Once you've got your lens in hand, you can
order a B4 Magic Lens Adapter, or the PowerLynx
Kit, remember it includes the adapter and everything
you need to power the zoom lens,
and you can get either of those starting today.
The B4 Magic Lens Adapter is normally $399.95,
but you can order it today for $249.95 – 
you're going to save $150!
The PowerLynx Kit is normally $499.95, but
you can order it today for $349.95. that deal
gets you the whole kit for a savings of $150
off of the full price.
So basically you spend $350 on a PowerLynx
kit, a hundred or two on the lens, and you've
got powered zoom back in your toolkit. Now remember, this is for the Black Magic Pocket Cinema Camera
users right now. If you're not using
the amazing BMPCC, which camera do you think
we should support next? Or maybe you've got

Lens Adapter? Well, jot it down in the comments

Thanks a lot for watching and thanks for all the support you've given us as we've been

My name's Bohus, thanks for watching.
