TTArtisan AF 40mm f/2 40mm
60 out of 100 low confidence 7 reviews
The TTArtisan 40mm f/2.0 pancake lens receives mixed feedback from users. While many praise its compact metal build, satisfying aperture ring, and excellent value for the price, significant issues with autofocus performance—including hunting, pulsing, and noise—are frequently mentioned. Image quality is generally good, but users note heavy vignetting and flare when shooting into strong light. Overall, it is seen as a budget-friendly option with trade-offs in AF reliability.
