Replay: Craig Marshall offers his insights after two weeks shooting in Japan using his extremely portable home-brew set-up.

I've just returned from Japan where I spent two weeks shooting a promotional video on Kyoto for a Taiwanese client. During my stay, I read Part III of Roland Denning's excellent Red Shark article: 'How to test cameras' - 'Test them in the real world!' and don’t forget Barry Braverman's recent account of shooting at night on the streets of Paris with the Sony FS7. Given my recent experience in Kyoto, both these articles struck a chord so if you'll bear with me, I'll quote some brief segments then embed my own thoughts and reflections on their topics.

I generally shoot independently, without a crew as such, so the ability to move quickly is an essential element, with only the basic necessities to hand. Kyoto, the very beautiful and former ancient Japanese Capital is a real Mecca for local and International photographers and video crews alike. The City has a very strong French influence now and has been often noted as the 'Paris of the East'. The historic Sanjo Bridge at dusk is a magnet for anybody who feels compelled to capture the late afternoon mood as the riverside cafes prepare for the evening throng. On any night, you'll find Japanese camera crews setting up on the Bridge with their bulky (Sony) HDCAM outfits, complete with their 'crew of thousands'. There's usually one guy wandering about with a hooded monitor so his producer/director can check the pictures shot by their lowly camera guy! Alongside the Japanese, there's the North American crews and still photographers with their predominantly Canon DSLRs, Asian photographers with their Nikons and let's not forget the European tourists with their smart phones clipped onto selfie sticks! Camera stores used to stock telescopic tripods by the dozen. Now its telescopic selfie sticks!

I shot my Kyoto programme in HD at 25fps which is unusual for me as I'm still a big fan of 50i and 50p frame rates because of their superior motion interpolation, but on this shoot I predominantly went for static compositions capturing movement within the frame. My camera for this highly mobile shoot was an older Sony mirrorless E-Mount 'Super 35' hybrid camcorder coupled to an Atomos Ninja 'Star' ProRes HDMI recorder, a Metabones Speed Booster, plus a nice selection of classic Carl Zeiss Full Frame prime lenses. Although the Ninja Star will perform a 50i 'pull down' to 25p, my prior camera tests revealed that the 25p/ProRes HQ combo produced video images with the highest possible picture quality.

Over the years, I have been fortunate enough to own and operate some of the world's best broadcast ENG zoom lenses from Canon and Fujinon for 2/3" cameras but these are rare and expensive for Super 35 format sensors so today, I stick with primes. Over the years, I've gradually assembled a comprehensive collection of the 'Contax' series of Zeiss manual primes from the '80s and '90s. Apart from their optical quality, their appeal is that they feature 'low contrast' glass and the same T* coatings as their legendary CP2 cinema cousins. That is, the Contax series were designed at the time for professional stills photographers who liked to manipulate their images in the darkroom after a shoot just as film makers do today using software to grade their films in post.

The Contax 35mm, full frame 'stills' lenses will handle a very wide range of lighting conditions with ease and their video pictures 'grade' particularly well, unlike some modern lenses which, in my opinion, often result in sharp but overly high contrast images. The Contax series is lauded by owners of RED cameras too as they cover the entire 8K Dragon sensor but on a Super 35 camera, they are best mated with the Metabones Speed Booster which almost completely restores their Full Frame FOV, increases MTF and corrects for any potential aberrations caused by the low-pass/infrared/sensor cover glass filter pack which can be an issue when using older ‘film’ lenses for digital acquisition. With all the talk about cameras these days, people tend to forget the effect a lens has on a picture.

As I've written before, one of the reasons why pictures from the Arri Alexa always look so good is that it is generally hired and operated by people who know how to light a scene and it's usually mated to some of the world's most expensive glass.

My 'home brew' camera amalgam is certainly not in the Alexa or FS7 class but it doesn't need to be because it perfectly suits the sort of work I mostly do.
