7Artisans has announced the AF 10mm F2.5 Max FF, a full-frame fisheye lens that offers autofocus with a 185-degree field of view. The lens is available for Sony E, Nikon Z and L-mounts and fills a gap for ultrawide photographers, as autofocus fisheye options for full-frame mirrorless cameras are particularly thin. 

At 510g (1.1 lbs), the AF 10mm is still relatively compact for a full-frame fisheye, particularly given its autofocus mechanism, F2.5 maximum aperture and metal construction. It is 60g (2.1 oz) less than 7Artisans’ manual focus 10mm F2.8 fisheye, though just slightly heavier than Canon’s RF 7-14mm F2.8-3.5 L Fisheye STM (476g (1.3 lbs)). Thankfully, it substantially undercuts Sigma’s bulky 1.36 kg (3.0 lbs) 15mm F1.4 fisheye.

7Artisans didn’t specify the type of autofocus motor, but says it is smooth and reliable enough for dynamic genres like street photography. It can focus as close as 0.15 m (5.9″). The optical design comprises 11 elements in 8 groups, including 1 aspheric and 2 extra-low-dispersion elements. It also features a nine-blade aperture diaphragm.

Despite the budget price and compact build, 7Artisans included some useful on-lens controls, which the company says are designed for video use as well as still photography. There are two customizable control buttons, an AF/MF switch and a clicked aperture ring. 7Artisans also says the lens supports A-B Focus, a video-oriented feature that automates focus transitions between two saved distances. 

The 10mm F2.5 is the second lens to carry 7Artisans’ Max designation, following the AF 135mm F1.8 Max. While the company has not yet fully defined the sub-brand, its first two entries suggest it is being used for higher-spec full-frame autofocus primes with more ambitious optical designs, metal construction and expanded on-lens controls.

The 7Artisans AF 10mm F2.5 Max FF lens is available for purchase as of today for $449.
