Fujinon Cabrio 19-90mm T2.9 PL Mount Zoom Lens.
Fujinon Cabrio PL Zomm
This is a new lens announced today by Fujinon. It’s a 19-90mm T2.9 PL mount zoom lens, which in itself isn’t particularly interesting, there are plenty of similar lenses on the market. What is very interesting is that this lens has a removable hand grip that contains motors for the zoom and iris. So this lens bridges the gap between a traditional 2/3″ ENG style lens and a PL cine lens. If you don’t need the servo functions you can remove the hand grip. The lens has standard 0.8mod gears on the focus, zoom and iris rings so conventional follow focus motors can be used. In addition the lens is very lightweight for a PL zoom. Clearly this lens is in response to the growing use of Super 35mm camcorders in documentaries, news and other similar applications.

I’ve been asked a couple of times for some frame grabs shot with one of the MTF B4 to super 35MM adapters that I designed. Well, here they are. Shot on a Canon C300 fitted with the adapter and an old standard definition Canon J16 zoom lens. It was late in the day when I shot this so it’s not showing the adapter in its best light and of course an HD lens would be even better.

Playing with lenses: 2/3″ Broadcast lens on PMW-F3.
OK folks. I wanted to see just how well a 2/3″ broadcast lens would work on an F3, but don’t have $5.5k to fork out on one of the Abel adapters. So with a bit of head scratching, a few, lowish cost lens purchases and a few hours in the workshop I cobbled together my own adapter. At first I tried a 2x magnifier but this didn’t quite give me full sensor coverage and was soft out in the corners. With a little more work I took the magnification up to 2.5x and I have clean corners. I’m really pleased with the performance, although one lens element needs changing for a higher quality element to combat some softness when the iris is fully open.
My old Canon J16x8 f1.8 becomes a 24 to 320mm f4(ish) par-focal lens which is actually quite handy. Next step is to make up a power cable for the lens so I can use the zoom servo.
I’m considering trying to find a manufacturer that can make these up for me properly, the converter should cost a lot less than $5.5k
Canon XF105, using OIS to correct zoom axis shift. (3D applications)
While I was in Singapore last week I got to play with a pair of Canon’s XF105′s on a Genus Hurricane 3D rig. We were able to use the programmable axis shift function to compensate for the way the zoom lenses don’t remain centred as you change focal length. Zooming in 3D with two cameras is very hard to do because of this shift, normally requiring very expensive matched lenses. With the 105′s and and a few minutes of adjusting we were able to do synchronised zooms (using the IR remote) that retained very good tracking and accuracy. This really is quite remarkable at this price point!
Can you use a 2/3" Zoom on a 35mm camera??
Can you use a 2/3″ B4 broadcast zoom on a 35mm camera. Well yesterday I would have said “no”, but having seen this video on the AbelCine web site, now I’m not so sure. UPDATE: OK Should have read the specs…. it’s only suitable for smaller sensors as it has a 22mm image circle, the F3 has a 27mm diagonal. It’s still a viable option for the AF100 however.

The HDx2 adapter magnifies the image to fill a 35mm sensor, doubling the focal length at the same time. This is very intriguing as 35mm zooms are few and far between and very expensive. There is a 2 stop light loss (well if you expand the image 2 times that’s what happens) but most broadcast zooms are pretty fast lenses to start with. I can’t help but think that the pictures might be a little soft, but if you already have decent 2/3″ glass then the $5,500 for the adapter might make a lot of sense. Anyone out there with experience of one of these? I’d love to know how it performs.

Chasing Vulcans.
Last weekend was the Royal International Air Tattoo. The largest military air show in the world. I’ve filmed this event many times and every year we try to do things a little differently to jazz things up. We have been shooting the show in HD for the past 3 years, this year it was entirely XDCAM with the exception of the minicams which were HXR-MC1P HD minicams. We had an EX1, EX3 and 3x PDW-700?s. As well as the usual extra long telephoto lenses we had a couple of gyro stabilized lenses including a schwem gyrozoom. While not an HD lens we found that the performance of the lens wasn’t too bad. There is no other lens that offers the degree of stabilization offered by the schwem so for the applications we were using it for we were happy to accept the slight softness in the corners. The application we had was to use it in one of the “Follow Me” vehicles used to marshall the aircraft around the airbase.
The high point of this was doing a tracking shot of the recently restored Vulcan bomber landing at Fairford. To do this we drove along the taxiway parallel to the runway at high speed as the Vulcan came into land. Once it had landed we got some impressive shots as it taxied right behind us. The Vulcan is a huge aircraft and to have this bearing down on you as it taxies with all four engines running (they normally use only 2) is quite a rush! The Schewm is a long lens so the Vulcan completely filled the frame, despite this the gyro stabilisation kept the images rock steady. Over the weekend I shot aircraft startups and GV’s using an EX3, then the follow me stuff with the schwem and PDW-70 as well as flying and display footage using a PDW-700 and 42x Fujinon lens. The most reassuring thing is that as these are all XDCAM cameras we know they will all cut together well in the final edit.
