Elevate your visual style and hardware aesthetic with the TTArtisan AF 40mm f/2 Lens For Sony E-Mount (Full Frame) (Silver). Masterfully sculpted from high-grade 5052 aerospace aluminum with a stunning silver anodized finish, this incredibly compact walk-around lens weighs a mere 167 grams. Its classic styling makes it a brilliant visual counterpart for both silver and black Sony Alpha mirrorless bodies, retaining exceptional balance whether you mount it to full-frame setups or compact APS-C cameras.
Beneath its vintage housing is a modern optical engine featuring 9 premium glass elements configured into 6 groups. The array integrates an calculated mix of extra-low dispersion (ED), aspherical (ASPH), and high-refractive-index lenses. This structural combination tames chromatic aberration and field distortion, maintaining crisp center contrast when shooting wide open. Driven by a smooth STM (Stepping Motor) + lead screw spindle, the integrated autofocus runs quietly and rapidly. It coordinates with native Sony processing to deliver precise real-time Eye AF, face detection, and automatic subject tracking for stills and video.
The lens barrel sets itself apart by providing a physical, clicked aperture ring that adjusts exposures in precise 1/3-stop detents down to f/16. It also features an "A" (Auto) stop position to hand aperture control back over to your camera dial. Its bright f/2 maximum opening ensures clean, handheld captures under low street lamps, blurring out busy backgrounds using a 7-blade rounded diaphragm iris. Close-up framing is managed easily down to a 0.4-metre minimum focus clearance. To streamline system upkeep, the included rear lens cap houses a built-in USB-C port, letting you apply drag-and-drop firmware upgrades directly from your desktop computer.
