Triad E-Mount to PL adapter

A little while back I was loaned a Triad PL to E-Mount adapter for review. E-Mount is the Sony mount used on the NEX-FS100, NEX-FS700 as well as The VG10, VG20 and NEX stills cameras. While more and more E-Mount lenses are becoming available from Sony and other DSLR lens manufacturers there will be many times when something more suitable for video work might be needed. One of the big issues with DSLR lenses is the very small amount of rotation on the focus ring to go from near to far, often only 45 degrees which makes accurate focus tricky. A good PL mount lens will have over 180 degrees of rotation. PL has been the industry standard for movie cameras for years and most rental companies have large ranges of PL lenses to choose from. So the ability to be able to use a PL lens on any super 35mm camcorder is always welcome. While I use DSLR lenses on my cameras for my day to day shoots, if I am doing a high end production such as a commercial then I will hire in the appropriate PL lenses for the job. Sony’s soon to be released FS700 is a camera that will, I’m sure end up getting used for many commercials as slow motion is a technique widely used to show off new products or ideas. As a result there will be many time in the future where I will need a PL adapter.

The Triad adapter is very solidly made, machined from high grade alloy with stainless steel and chrome plated steel inserts. One of the very nice features is that the adapter has a built in adjustment for the back focus distance. A locking outer ring on the adapter can be rotated to alter the physical distance between the PL receptor and the E-Mount bayonet. This will allow the user to calibrate the back focus or flange back distance so that the focus witness marks on any PL lenses will be 100% accurate. It will also ensure that PL zooms will track focus correctly through the entire zoom range. As the FS100 and FS700 don’t have built in back focus adjustments this really is a vital thing to have. The Sony E-mount was only designed to support the weight of light weight DSLR type lenses so the Triad adapter has a support post that can be attached to 15mm or 19mm rails (via a suitable bracket) to help carry the weight of heavy PL lenses without over-stressing the cameras E-Mount. One note from Triad is that the Sony PL lenses supplied with the kit that comes with the PMW-F3 do not fit this adapter. There are quite a few PL mounts that don’t accept the Sony PL lenses without shaving a bit of metal from the Sony lenses mount. So this isn’t a flaw with the Triad adapter, it’s a non standard quirk of the Sony PL lenses.
There’s really not much more to say about this mount. It’s well made and does what it designed to do.

  1. Thanks, Alister! That back focus adjustment can come in very handy, I’m sure. We’ve been using the 16×9 PL mount for the FS100, and although there’s no back focus adjustment, it hasn’t been a problem since we’ve been using primes. And the 16×9 adapter does fit both Sony and Zeiss CP.2 PL mount primes.

  2. Every micro-adjustment on a PL mount I’ve ever used has drifted , (Red One for example). It’s not the kind of thing you want to have move on you when you’re working. As you don’t know until it’s too late! —edited by admin—-. I ended up spending a little more and getting the Sony E to PL mount made by Hot Rod Cameras.

    NOTE FROM ADMIN: While I welcome comments they must be balanced and considered. This comment read as a plug for the Hot Rod adapter saying that all others are useless. If Hot Rod wish to supply an adapter for review then I would be glad to take a look at it.

  3. As this review is probably a few years old, I wonder what Sony E to PL adaptor you have tested and would recommend. I’ve looked at the reviews for the Metabones and MTF which seem to be the best of the lot, although the MTF has a 1.11 magnification, I haven’t read about any glass in the Metabones.
