The SCL-Z18X140 is a zoom lens compatible with the Sony FZ mount, featured on the PMW-F3 and, the recently announced, PMW-F5 camcorders.
The SCL-Z18X140 is a 14x high-power zoom lens designed for high-end production. Offering 18mm-252mm at T3.8 (Wide) the lens equivalent, in full-frame 35mm photography terms, is 27 - 378mm. The SCL-Z18X140 has been specifically designed to fit to the PMW-F3 and PMW-F5, via the camcorder’s FZ mount, expanding the operational flexibility by providing auto focus, auto iris, image stabilization and servo zoom.
I shot this in a small village near where I live on a Carl Zeiss CP.2 15mm T2.9. The NEX FS100 has a Super 23mm sensor and so the crop factor on this lens is 1.5 so the images you are watching have an equivalent Field of view to a 22.5mm focal length.
I am an Ambassador for Carl Zeiss and I was loaned this lens before NAB to test and evaluate- I shot this film as a test and used the 15mm exclusively in every shot. The images have been corrected for luminance only everything else is as shot.
a while back we were asked to put together some educational pieces for tiffen/steadicam on the different rigs they offer. unfortunately we couldn't license the NFL footage for tiffen/steadicam but they were kind enough to allow us to use it on our blog, so we have a version on our blog with some of the nfl footage shot with the flyer.
Richard Schleuning of Carl Zeiss USA explains the difference between F-Stops and T-Stops in this little Quick Take. F-Stop is a mathematical equation based on the physical size of the lens, where T-Stops take the light loss from the front element to the film plane into account in that equation making them equal across all manufactures.
