Transvideo PMW-F3 replacement base assembly.

A package arrived in the mail from Transvideo the other day. In it was one of their rather nice base plates for the PMW-F3. This plate isn’t simply a plate that it is attached to the bottom of the camera. It is in fact a complete replacement for the bottom end of the PMW-F3. Transvideo are best known for their superb high end monitors, robust, built to last monitors you often find on movie sets as they they offer a range of highly accurate calibration tools and fully calibrated displays not found on many lower cost monitors. In addition Transvideo’s 3D monitors are the monitors of choice for many 3D productions and stereographers as they offer special monitoring options that allow for very accurate measurement of 3D offsets and geometry.  This new base plate is a bit of a departure from Transvideo’s normal product lines. I suspect it’s come about because Transvideo’s 3D expertise led them to realise that one of the PMW-F3′s biggest issues for 3D is that the standard base plate isn’t particularly stable which can adversely affect alignment when used on a 3D rig.

This is a problem not only for 3D but also for use with long and heavy lenses as the camera can wobble and flex on the tripod. The two 1/4″ threads on the F3 are far from ideal and the third thread at the back of the camera is offset from centre making it hard to use. By replacing the original very thin base plate of the camera ( it is is really, really thin) with this much more robust base plate you spread the loads imparted on the tripod mounting points across the entire bottom end of the internal chassis of the F3, not just the 4 teeny tiny screws that hold the sony tripod mount in place. Fitting is very easy, 8 small screws are un-done to remove the original Sony base panel, which simply lifts off and then the new Transvideo plate, complete with beautifully CNC machined cooling slots simply attaches in it’s place. Now my F3 has a perfectly flat base with both 1/4″ and 3/8″ threads (hooray!!) as well as a large number of M4 threads towards the outside. Now I can fit standard Arri accessories without having to fudge together different plates and screws to make them fit.

Frankly this is how Sony should have done this in the first place, but well done to Transvideo, now my F3 is really starting to feel like a proper camera. The only very minor down side is that you loose your serial number plate as this is attached to the original Sony part. The fit is superb and it looks great too. 10/10.

As well as the base plate I also received a little finger tab that attaches to the Sony PL mount. this little wing tab makes it much easier to remove and attach PL mount lenses as you can grip the lens with one hand and push the tab with you thumb to release the locking ring. It’s only a small thing but it makes the F3′s PL mount much more user friendly.
