Recently, 7Artisans – specialized in manual focus lenses – has launched a fixed focal length lens f / 1.8 for the mirrorless cameras with Sony’s crop sensor. (E mount), Fujifilm (X mount), Olympus / Panasonic (M43 mount) and Canon EOS M (EOS-M mount). The lens has a focal length of 50 mm when mounted on cameras with crop sensors that will have a similar angle of view on the full-frame sensor for the portrait category.
The body of the tube is made of aluminum alloy, creating a strong sense of use. With an optical structure consisting of 6 lumped layers in 5 groups combined with 12 mouthpieces when opening a large aperture of f / 1.8, the 7artisans 50mm f / 1.8 lens gives a dreamy, seductive background and can be used well under conditions dim light.

When mounting a 7artisans 50mm f / 1.8 lens on mirrorless cameras of firms with different sensors, we have the same viewing angle with the focus on the full-frame sensor as follows:
On the Canon EF-M, the 50mm focal length will be equivalent to the viewing angle of the 80mm focus on a full-frame sensor
On Sony E (APS-C), the 50mm focal length will be equivalent to the 75mm focal point of the full-frame sensor
On the Fujifilm X, the 50mm focal length will be equivalent to the 75mm focal point of the full-frame sensor
On Micro Four Thirds, the 50mm focal length will be equivalent to the viewpoint of a 100 mm focus on a full-frame sensor
