Creamy bokeh, a middle size that fits comfortably in the hand.
The "SG-image AF 85mm F1.8 STM" is a medium telephoto prime lens designed for 35mm full-frame cameras. Its 85mm focal length, ideal for portrait photography, and large F1.8 aperture allow for a shallow depth of field, creating three-dimensional imagery and soft, creamy bokeh. The autofocus system, utilizing a stepping motor (STM), provides quiet and smooth operation, making it easy to use in video shooting environments. The optical design, comprising 11 elements in 9 groups (including 3 high-refractive index lenses and 1 ED lens), and its coatings ensure high contrast and clear rendering even at maximum aperture. Combining a lightweight design with the high rigidity of a full-metal exterior, this lens is well-balanced with mirrorless camera bodies and is versatile enough for everything from casual snapshots to professional portrait photography.
Soft and creamy portrait depiction
From F1.8 wide open, the lens ensures sharp resolution in the center while achieving a natural and gentle bokeh that suppresses distractions. This enables three-dimensional portrait rendering where the subject stands out.
Mid-size design that balances lightness and texture
It features a premium full-metal exterior while maintaining a lightweight design. It's well-balanced with mirrorless cameras and sized for everyday portability.
Excellent rendition even in backlit conditions
Coatings that suppress flare and ghosting help maintain contrast and support clear rendering even in backlit conditions. The design is also suited for outdoor shooting, as it easily preserves natural three-dimensionality.
