If you plan to do videos periodically and have someone in your team who has experience with videography, or willing to learn, it can be reasonable to invest in your own equipment.
Below a short guide on equipment you'll need:
We recommend Sony A7 / A7s mirrorless cameras with interchangeable lens.
These camera provide good range of professional features, good low light performance, and in-body image stabilization. Wide range of lenses can be adopted for this system, including very modestly priced, and yet well performing vintage manual lenses like Canon FD, Nikon, Olympus, etc.
Typically you would need a several lenses, including:
If you're on a budget, you may get away with just a single zoom lens. Normally that would be a classic 24-70mm range, Tamron's 28-75 f2.8 is well priced and performs very well.
Tripod is a foundation of all video work and well worth investment. There are plenty of options on the market.
Slider is a simple tool to make your shot looking more dynamic and professional. We use Rhino Sliders, however there's plenty of budget options on the market right now.
We use Sennheiser wireless mics, however any budget lavalier mics will do the job for interviews. If you're serious about sound and have extra budget, ZoomH4n might just be a thing for you.
