Weight and easy handling are less of a concern when the camera is mounted to a crane. And this is exactly the kind of scenario you'll find when shooting big-budget commercials, for which Martin prefers to use prime lenses.
For a high-end truck trailer commercial, Martin was equipped with the full-frame Canon EOS C700 FF
, and the full-size range of Canon CN-E prime lenses, from the CN-E14mm T3.1 L F
to the CN-E135mm T2.2 L F
. That's a lot of glass, so what did each lens do and what was his experience of switching between them?
"We had driving shots, talking heads, impressions from the factory, plus some critical conditions such as huge windows in the office scenes and hard sun reflections in the car paint," recalls Martin. Such a range of shots required multiple lenses that could transition well for a consistent look.
"I like the colour consistency of CN-E primes and their smooth bokeh – it was important to have a shallow depth of field for a clear futuristic look. As a DoP you know that a wide-angle lens can distort faces, so we used the Canon CN-E50mm T1.3 L F
and CN-E85mm T1.3 L F
lenses for talking heads. To get those dynamic shots in the factory, we used the Canon CN-E14mm T3.1 L F to CN-E35mm T1.5 L F
lenses with a Primo-Dolly. In the pit we even used the 14mm lens and there were almost no distortions – there is much less distortion using full-frame. For driving shots, we also used the longer primes: 85mm and 135mm."
