What We Like
+Compact and lightweight all-metal construction at an affordable price point ($168)
+Sharp center performance with good low-light capability thanks to f/2 aperture
+Mechanical aperture ring with satisfying click-stops—rare in modern autofocus lenses
+STM motor provides quiet, smooth autofocus suitable for video and stills
+USB-C firmware update port for convenient maintenance and improvements
Worth Knowing
−Strong vignetting at f/2 that remains noticeable even when stopped down to f/5.6
−Soft corner performance on full-frame; corners only sharpen noticeably by f/8-f/11
−Significant focus breathing that may be problematic for videographers
−No weather sealing and limited close-focus performance (higher minimum focus distance than competitors)

Read our notes on general
The TTArtisan AF 40mm f/2 is a very compact and lightweight lens that offers strong build and optical qualities, including low distortion and good sharpness across most of the frame. It features a dedicated aperture ring with one-third-stop increments, which is an uncommon trait for modern autofocus lenses at this price. The lens is built entirely from metal, giving it a sturdy feel that's unusual at this price point. However, vignetting is very strong at f/2 and remains noticeable when stopped down, and close-up performance is poor wide open with contrast nearly disappearing until you reach f/4.
