Overview

The TTArtisan AF 50mm f/1.8 Neo is a full-frame autofocus standard prime from TTArtisan's Neo series, offered for Sony E, Nikon Z and L-mount. The Neo concept is a simplified lens: TTArtisan removed the focus ring and the aperture ring for a more direct shooting experience, and it says the body supports personalisation with stickers, 3D printing or custom paint.

Optical design

The lens has 12 elements in 8 groups and a 7-blade diaphragm covering f/1.8 to f/16. The angle of view is 45 degrees, which TTArtisan describes as close to human vision. The minimum focus distance is 0.48 m and the filter thread measures 52 mm. According to TTArtisan, the lens delivers sharp images from center to edge on full-frame and APS-C cameras.

Autofocus and handling

Autofocus is driven by an STM motor and supports eye and face detection. With no focus ring and no aperture ring on the lens, the aperture is set on the camera.

Build and size

TTArtisan states a weight of 156 to 167 g depending on the mount and promotes the 156 g figure. Dimensions per mount (diameter x length) are 61 x 51.5 mm for Sony E, 66 x 54 mm for Nikon Z and 64 x 50 mm for L-mount.

Other full-frame 50 mm f/1.8 lenses in the database are the Sony FE 50mm F1.8, the Nikon Nikkor Z 50mm F1.8 S, the Canon RF 50mm F1.8 STM and the Panasonic Lumix S 50mm F1.8. These conventional lenses keep a focus ring. The TTArtisan stands out through its low weight and the simplified Neo concept.
