It is compatible with Sony's Eye AF technology, ensuring precise focus on the subject's eyes. The lens also features a dust and moisture-resistant design, making it suitable for use in various environmental conditions. The physical design includes a focus hold button and an aperture ring with a de-click switch for smooth, silent aperture adjustments during video recording. With a weight of approximately 820 grams, the Sony SEL85F14GM balances well on both full-frame and APS-C Sony E-mount cameras, making it a versatile addition to any professional's toolkit.
