7Artisans' budget autofocus portrait prime for Sony FE with f/1.8 and STM motor.
The 7Artisans AF 85mm f/1.8 is an autofocus portrait prime for Sony FE-mount bodies, providing the classic 85mm portrait perspective with f/1.8 maximum aperture and a built-in AF motor for continuous tracking. Eleven aperture blades produce smooth, rounded bokeh at wide apertures — a higher blade count than most comparable portrait primes. At 438g and 62mm filter thread it is compact for an AF 85mm. Available in Sony FE, Nikon Z, and other mount versions.
The optical design uses 10 elements in 7 groups, including ED, high-refractive-index, and aspherical elements. Eleven aperture blades produce smooth bokeh. The 62mm filter thread is a common portrait prime size. At 438g the lens is moderate for an AF 85mm f/1.8. Minimum focus distance of 0.80m — longer than some 85mm alternatives, requiring a greater working distance for minimum-focus framing. Autofocus motor enables continuous tracking for portraits and events. Electronic contacts provide EXIF data and AF communication with the body.
The 85mm perspective on full-frame produces the standard portrait compression and subject-background separation of this classic focal length. At f/1.8 the background rendering and subject isolation are practical for event, wedding, and portrait photography where a native Sony FE 85mm would cost more. The eleven aperture blades produce a more rounded bokeh shape than the seven-blade alternatives at comparable prices. The 0.80m MFD is the primary practical limitation for close-up portrait compositions.
On the used market the 7Artisans AF 85mm f/1.8 is affordable for an AF portrait prime with high blade count. Condition checks: AF motor response for smooth tracking, front element condition, aperture ring operation, and confirm the mount version matches the target body. The Sony FE 85mm f/1.8 provides Sony-native AF integration and weather sealing at a modest premium. Compatible with Sony FE-mount full-frame and APS-C E-mount bodies in the Sony FE version.
