For the past two years, my most used camcorder for documentary filming has been the SONY A7Siii. It is small, has excellent autofocus and excellent image stabilisation. I have an Atomos Ninja V attached to my SONY A7Siii and I record Apple ProRes footage with the Ninja V.
But I don’t always use the same camera. If a client specifies a camera, I rent that camera and shoot with it. There are many companies in Tokyo that lend out professional video cameras. Here are three of them that I often use.
Toyo Rental
https://www.toyo-rental.co.jp/
This is the company I use the most. They offer the latest models at reasonable prices. They are conveniently located near the National Stadium.
Tokyo Offline Center
https://www.toc-net.jp/
You can complete your booking online. Rental rates are reasonable. They deliver the equipment to your office the day before.
Video Service co., LTD
https://www.videoservice.tv/
When I needed an ALEXA Mini last year for an urgent project, they lend it to me straight away. They have a large selection of lenses for cinematography.
