Zunow EOS to PL Adapter


I was very Kindly offered a demo Zunow PL mount adapter for use with EOS cameras this week, and I snapped up the opportunity to test it out. Ive still not had a chance to play with the current offerings from companies like DENZ or HoTRod Cameras, so this was my first chance to pop some Cinema Glass on my little 5DMKII. This is a preliminary report on the unit, I will try and shoot some video and post examples if my schedule allows. (which isnt looking to likely at the moment!)

The Unit itself is a relatively low key affair, no flashy primary colours like many of the HDSLR AKS you see dominating the market, and unless you knew what you were looking at, it would probably go unnoticed. I like this, Im not a big fan of bright colours all over the camera, keep it all black, and i’m a happy bunny.

The Zunow comes in 2 pieces, the adapter itself, and a lens support/baseplate with a quick release wedge mounted to it for ENG style tripods. This is easily removed, (see below) and can be refitted with an OConnor Wedgeplate. (I had to do this to fit our 2060 Head.) The baseplate has a screw which when attached threads through into a lens support fitted on the underside of the adapter itself. For heavier lenses, like the Optimo, a second lens support would be required, but for all the lenses I tested it seemed rock solid as is.

In house we have RED Pro Primes, and zooms, all of which fitted perfectly with the adapter, with the only exception being the 18mm.

The list of lenses I have tested so far that fit:

RED Pro Primes 25mm, 35mm, 50mm, 85mm, 100mm

RED Old style 300mm

RED Zoom 18-50mm, 50-150mm

(I had an optimo 24-290 and a set of Arri Tilt Shifts with me all week this week, and whilst I had no chance to get them on the adapter, comparing the rear elements leads me to believe  99% they both would work )

I popped a few Ultra Primes on the mount, but had no luck as the rear element was too large. The one weird result I encountered was when trying the Duclos 11-16mm PL conversion. By all accounts it should have worked, the rear element was no larger than the RED lenses, but for whatever reason, I could not get it to fit the adapter. I suppose this isnt the end of the world, the Lens would vignette on the 5D Sensor anyway, and a much cheaper version can be found in its original form from Tokina, but it would be nice to have all Cine style lenses on hand fit.

The lenses themselves do behave slightly differently when used on the adapter, firstly the adapter is a piece of glass, and as such it causes a light loss of around 2 stops. Secondly, there appears to be a cropping effect in comparison to the same shot when using FF SLR lenses.

The main strongpoint of this adapter? There is Zero modification required to either the Camera or lens. Other offerings will need the camera body to be heavily reworked, and can cost over 2 or 3 times the cost of the original camera. The Adapter retails for around EUR2350 and can be ordered from Adorama, or directly from the distributer ALPHATRON.

If there is interest Ill try and up some comparison Shots from the Adapter, but Im crazy busy at the moment!
