With a very portable focal length designed for everyday photography, the TTArtisan AF 40mm f/2 Leica L mount lens is a versatile choice for mirrorless cameras. With its fast f/2 aperture, it performs well even in low light conditions and nicely separates the subject from the background, providing a pleasant bokeh effect. A USB port integrated into the durable all-metal lens cap allows for easy firmware updates, while its compact and lightweight design makes it ideal for street, travel and documentary photography.

Fast autofocus with face detection
STM stepping motor ensures fast and quiet focus, with face detection support, so that the main subject is always sharp when taking portraits.

Soft bokeh and strong low-light performance
Take advantage of the f/2 aperture and create portraits with silky blurred backgrounds that highlight your subject. You can capture quality images even at night or in poorly lit environments without having to raise the ISO value to the sky.
