MFT 45mm Standard Cine

Tested in real production counts across diverse cinematic environments, this professional lens demonstrates exceptional reliability for high-end filmmaking. Technical measurements confirm that the optical path delivers superior light transmission and precise color matching. Industry endorsement from top-tier directors of photography confirms its status as an authoritative tool for digital cinema production, meeting the most demanding standards for natural perspective visual storytelling and professional production.

High-Resolution Standard Optical Construction

The technical definition using specialized glass elements reduces chromatic aberration and color fringing significantly. Improved resolution ensures high contrast such as razor-sharp edge-to-edge clarity throughout the entire frame. Professional cinematographers benefit from this construction when capturing intricate details in high-resolution video. This precise engineering ensures that digital sensors capture natural textures with absolute accuracy for professional grading, providing a consistent visual signature for any project on MFT sensors.

T1.5 High-Speed Aperture Implementation

The fast T1.5 aperture behavior enables superior exposure control in low-light environments without introducing digital grain. High-quality circular bokeh creates beautiful background separation for aesthetic narrative shots. Narrative filmmakers such as commercial directors rely on this feature for creating a professional look. This large aperture allows for extreme shallow depth-of-field control, providing a cinematic aesthetic that isolates subjects effectively from distracting backgrounds with creamy textures.

Professional Cine Gear Focus System

The manual focus system provides smooth and predictable focusing for professional cine workflows. Industry-standard 0.8 MOD gears improve consistency for focus-pulling tasks on busy sets. Professional crews benefit especially in scripted narrative scenes where timing is essential. The 180-degree focus rotation provides ample space for fine-tuning focus during complex camera movements and tracking shots, ensuring every transition is perfectly timed and sharp for the professional narrative.

Durable Weather-Sealed Metal Chassis

The lens weighs 2.5 lb (1.1 kg) with a barrel length of 4.3 in (109 mm). The magnesium and aluminum housing adds durability for heavy-duty production environments and field use. Rental houses value this when providing equipment for long shoots. Its standardized Magnetic Mount System allows for quick matte-less filter swaps, making it an efficient choice for small crews and fast-paced commercial production environments globally for mobile digital filming.

MFT Mount Compatibility Adaptability

The MFT mount attaches to professional Micro Four Thirds mirrorless and dedicated digital cinema cameras. Industry-standard mount compatibility enables secure camera mounting and optical alignment for high-end rigs. Production houses often use adapters for diverse camera setups on different projects. This robust mount ensures that the lens remains perfectly centered and stable, even when using heavy lens support systems and high-torque wireless focus motors during capture.

Professional Standard Prime Deployment

The 45mm capability supports natural-perspective tasks for professional directors of photography and cinematographers. Low distortion reduces spatial distortion in tight work settings and interview locations. Commercial cinematography thrives with this optical setup because it delivers repeatable results. This deployment is ideal for character-driven narratives, fashion cinematography, and any production requiring the natural compression and professional bokeh effects of a standard prime lens.

Irix 45mm Cine Maintenance Protocol

Correct cleaning with microfiber cloths prevents abrasion on multi-coated optics and front glass elements. Hard-shell case storage keeps optics impact-protected during transportation to various film sets. Pro Tip: Keep the front magnetic cap on when not in use for long-term reliability and dust prevention. Includes a 2-year limited warranty for professional peace of mind, covering all optical and mechanical components for years of production.
