What is the 7Artisans 40mm F2.5 AF ? 

In recent years, with the spread of social media and vlogs, the photography style of “casually recording everyday moments” has become more widespread. Accordingly, there is a growing need for compact, lightweight lenses with excellent mobility. Meanwhile, as camera equipment becomes more powerful, it also becomes larger and heavier, leading to complaints such as “The lenses are so heavy that I rarely take my camera out” and “My camera just stays put away.”

This product is a compact, lightweight lens that responds to these changes in photography styles and is suitable for a wide range of uses, including snapshot photography.

The lightweight design of the lens, weighing approximately 90g, reduces the burden on the camera when attached, making it easy to capture everyday moments. Its compact size makes it easy to fit in a bag, and its easy-to-use 40mm angle of view make it the perfect everyday lens for when you’re out and about.

Optical Design

The optical design with an F2.5 maximum aperture achieves a soft bokeh that gently accentuates the subject. Rather than focusing solely on sharpness, the gentle gradation that blends the contours nicely captures the atmosphere and mood of the scene. In environments with many point light sources, such as illumination, the lens also produces a bubble-like bokeh effect with distinctive contours, reminiscent of soap bubbles, broadening the scope of expression.

Equipped with an STM (stepping motor), it achieves quiet and smooth AF drive. It supports eye AF and subject tracking, capturing the subject quickly and clearly. It also supports smooth AF operation when shooting video.

Despite its compact body, it offers enhanced operability and an intuitive shooting experience. It features a click-type aperture ring and an AF/MF switch. Furthermore, you can quickly access various functions by setting the Fn custom button on the camera body. The mount also features a Type-C terminal, allowing you to connect to a PC for firmware updates.
