Overview

The TTArtisan AF 14mm f/3.5 is a tiny autofocus wide-angle lens for APS-C mirrorless cameras, offered for Sony E and Fujifilm X. On APS-C, 14 mm is equivalent to about 21 mm on full frame, and TTArtisan quotes a field of view of 92 degrees.

Optical design

The lens has 8 elements in 7 groups with a 7-blade diaphragm covering f/3.5 to f/16. The minimum focus distance is 0.25 m. The front takes a small 39 mm filter thread, and a lens hood is included.

Autofocus and handling

A stepper motor drives the autofocus, with eye, animal and vehicle recognition supported. The barrel carries an aperture ring with an A position and an f-stop scale, as the manufacturer's dimension pictures show, which is unusual for such a small autofocus lens. A Type-C port for firmware updates sits in the rear lens cap, and a center-pinch front cap is supplied.

Build and size

The body is made of 5052 aviation-grade aluminium. TTArtisan states about 98 g. Dimensions per mount are 62 x 31 mm for Fujifilm X and 62 x 32 mm for Sony E (diameter x length), so the lens is a true pancake.

Where it fits

Other wide primes for APS-C in the database include the Fujifilm XF 14mm F2.8 R, the Fujifilm XF 16mm F2.8 R WR, the Sony E 16mm F2.8 Pancake, the Viltrox AF 16mm F1.8 and the Viltrox AF 20mm F2.8. They differ in focal length and aperture. The TTArtisan stands out through its weight and its very small size.

Pros and cons

Pros

Weighs only about 98 g and is 31 to 32 mm long
Wide 92 degree field of view
Autofocus with eye, animal and vehicle recognition
Aperture ring and metal body
Close focus to 0.25 m

Cons

Maximum aperture of f/3.5 is modest in low light

No optical stabilisation

Verdict

The TTArtisan AF 14mm f/3.5 is aimed at photographers who want a wide-angle lens that disappears on the camera. The data show an exceptionally low weight and a physical aperture ring, at the cost of a slow f/3.5 aperture. It suits travel, street and landscape use in good light, while faster wide-angle primes from other makers suit users who shoot in dim conditions.
