I did some tests a while ago with Canon CN-E primes lent to me by Foto Format. At the moment the only lenses available were 24mm T1.5, 50mm T1.3 and 85mm T1.3. I put them all on my Sony NEX-FS700 camera with and without SpeedBooster. I didn’t adjust the aperture so you can also see how much more light you get with the SpeedBooster. At the end of the video there is also some shots with them on a Blackmagic Pocket Cinema Camera with a dumb Canon adapter.
The lenses are already low light monsters with T1.3 and T1.5 but with SpeedBooster you get another stop more so you are in the range of the SLR Magic HyperPrime CINE 35mm and 50mm lenses.
My thanks goes to Tjaša Kokalj who patiently sat in front of the camera while I fiddled with the cameras and lenses.
The only thing that bothers me with this lenses is their mount. Canon EF mount is just not good enough for proper cine lenses. It would be great if they also came in the PL mount version. You can of course get them converted at Duclos lenses but it is not cheap.
As a standard I also did a flare test. At the beginning there are all three Canon CN-E lenses continued with all my other lenses.
Update: I will post some additional footage of the flares. I shot some cars, crossroads, headlamps at night so you can see first hand experience and real life examples.
Below are the few photos I took while I had the lenses on the test.
