Discover our latest 50 mm F1.4 G Master prime
Two high-precision XA (extreme aspherical) lens elements effectively correct distortion and most types of aberration. This new optical design also employs an ED (extra-low dispersion) glass element to suppress chromatic aberration. Our original Nano AR Coating II on the lens surfaces greatly reduces internal reflections that can cause flare and ghosting.
Innovative optics and an F1.4 maximum aperture combine to deliver magnificent bokeh. Deep, creamy background and foreground bokeh at F1.4 are ideal for making portrait subjects stand out. Advanced features that contribute to superb bokeh quality include XA (extreme aspherical) elements that effectively prevent onion-ring bokeh, and careful optimisation of spherical aberration during design and manufacture.
XA (extreme aspherical) elements precisely positioned in an innovative design, high-thrust XD linear motors and the latest compact circular aperture unit work together in a large-aperture high-resolution lens that is only 80.6 mm in outer diameter and 96.0 mm in length while weighing just 516 grams (18.3 oz). A unique blend of mobility and low-light performance make it an ideal choice for everything from portraits to snapshots.
The lens’s focus group is driven by our high-thrust XD (extreme dynamic) linear motors and an advanced control algorithm for smooth, responsive focus drive. Noise and vibration are minimised for refined, quiet AF operation that can be a huge advantage when shooting movies. Movie subjects are smoothly captured and tracked even when shooting at 120 fps or other high frame rates.
Linear Response MF provides a manual focusing response that rivals mechanical lenses, and is more than responsive enough to produce smooth rack focus for movies. An iris lock switch can be locked to fix the aperture ring at the “A” position to prevent unwanted changes, or manually set from F1.4 to F16. Two customisable focus hold buttons and an AF/MF focus mode switch provide extra shooting versatility.
The front lens element features a fluorine coating that repels fingerprints, dust, water, oil and other contaminants while making it easier to wipe off any that do get onto the lens surface. A dust- and moisture-resistant design provides extra reliability for outdoor use in challenging conditions.
G Master series lenses take imaging and expression to previously unattainable levels with a stunning blend of extremely high-resolution and softly dissolving background bokeh.
