Shoot Wide Open with Confidence
The Master Primes’ optical quality holds up remarkably well even at their fastest aperture of T1.3. You can confidently shoot in very low light and achieve a beautifully shallow depth of field without worrying about a significant drop in image quality.
Leverage Lens Data System (LDS)
If your camera supports it, the built-in LDS provides frame-accurate metadata. This is valuable for a variety of tasks, from simplifying a DIT’s workflow to assisting with post-production and visual effects.
Benefit from Minimal Breathing
The near-zero focus breathing of these lenses is a key feature. When you do a focus pull, your image’s field of view will remain stable, which is crucial for professional cinematic work.
Consistent Mechanics for Efficient Work
The consistent 114mm front diameter and gear positions across the set simplify on-set work. You can swap lenses without having to adjust your matte box or follow focus, saving valuable time.
Manage the Look
The Master Primes are a clean, high-contrast, and technically precise set of lenses. If you’re going for a more stylised or vintage look, you might want to pair them with a filter or choose a different lens set.
