TTArtisan has announced the AF 40mm F2, a ‘normal’ focal-length prime for full-frame Sony E and Nikon Z mount cameras. It’s made to be fast, compact and affordable despite having features like a clicking aperture ring and all-metal construction.
The lens is made of nine elements in six groups, with two high-index elements, one extra-low-dispersion element and one aspherical lens. It has seven aperture blades, and can focus on objects as close as 0.4m (15.7″).
Autofocus is handled by a stepping motor. The lens can fit 52mm filters, and weighs 167g (5.9oz), despite being made out of aluminium. It also comes with a metal, petal-shaped lens hood.
The lens is available now from TTArtisan’s website and only costs $168, which is a very approachable price. If you’ve never shot with a ‘normal’ focal length lens before (as in, a lens that offers a field of view that’s close to what the human eye does), it could be an affordable way to try it out.

Our DPREVIEW Tribute:
After nearly 25 years of operation, DPReview closed on 10 April 2023. This difficult decision was part of the annual operating plan review that parent company, Amazon, shared earlier this year.
Over the course of 25 years, DP Review built up a reputation as being one of the most informative places to go for information about that new camera or lens you’re after. DP Review began as an independent reviews site based in the UK in 1998, the brainchild of Philip and Joanna Askey, but it was eventually purchased by Amazon in 2007 and relocated over to Seattle in the USA in 2010.
Cheers DPReview – thanks for the great work and content that guided photographers, videographers and techno junkies the world over!
