Using this adapter with a B4 lens gives you an impressive zoom range, like 28mm to 420mm, all in one parfocal lens that holds focus throughout the zoom. Many B4 lenses also stay fast at around T2, so you get bright, clean images from wide shots to tight close-ups — perfect for sports, wildlife, or live events on your RED camera.
FEATURE
Optical Optimisation
Utilises Blackmagic’s B4 adapter to optically correct the lens for RED’s single-chip sensors. This avoids the need for expensive optical expansion adapters that introduce data-heavy oversampling and serious light loss.
FEATURE
Perfect for Slow Motion
Supports native RED recording modes from 1080p to 3K - within the optical range B4 lenses were designed for. On Gemini, for example, you can shoot up to 240fps with zero sensor crop.
FEATURE
Minimal Light Loss
Expect just 1/3 stop of light loss vs up to 3 stops on conventional B4-to-PL optical adapters. Great for low-light work and stopped-down shooting.
