Sony FE 85mm F1.4 GM
Classic Portrait Focal Length (85mm): Ideal for portraits, providing a natural perspective and subtle perspective compression, making the subject stand out.
Ultra-Large F1.4 Aperture: The fast maximum aperture delivers excellent low-light performance and the ability to create the signature “creamy” G Master bokeh.
XA (Extreme Aspherical) Element: Uses an ultra-high precision XA element to suppress the “onion-ring effect” in bokeh and ensure superior sharpness.
Super Sonicwave Motor (SSM) and XD Linear Motor: Combines advanced focusing motors (typically SSM for early versions, or XD Linear Motor for newer models) to deliver fast, precise, and quiet AF speed.
11 Circular Aperture Blades: The large number of aperture blades (in its class) helps create round, smooth, and aesthetically pleasing out-of-focus areas.
Weather Resistance Design: Dust and moisture resistance (Weather Sealing), ensuring safe and reliable operation.
Description
1. Image Quality and Signature Bokeh:
- The 85mm F1.4 GM lens is famous for maintaining optimal sharpness at the focus point (on the subject’s eye) even when wide open at F1.4, while the background is rendered into a smooth, artistic haze.
- ED (Extra-low Dispersion) elements minimize chromatic aberration and fringing, maintaining high color quality.
2. Professional Controls and Flexible Operation:
- Aperture Ring: Features a physical aperture ring with an optional De-click switch, allowing filmmakers to adjust the aperture smoothly and silently when shooting video.
- Focus Hold Button: Customizable to lock focus or assign other functions (e.g., Eye AF), speeding up workflow. AF/MF Switch: Quickly switches between autofocus and manual focus.
3. Reliable AF Performance:
- Despite the wide F1.4 aperture requiring a large focusing group, Sony’s focusing motor system ensures fast and accurate AF, especially when tracking subjects with Sony Alpha camera’s Real-time Tracking and Eye AF features.
