Distinctive retro look
The lens design is classic and retro, with a delicate diamond-shaped structure of the focus ring and the bayonet ring that adds friction when using the lens and has a nice tactile quality to it.
Compatible Mounts
TTArtisan 250mm f5.6 is designed for the M42 mount, but you can use it on any mount you like with an adapter ring.
Easily adapted to Sony, Fuji, Canon, Nikon, Hasselblad and other cameras
NOTE
It is a normal phenomenon that the centerline of thread mount lens is not aligned with the centerline of the camera, and it does not affect the use. If you need an adapter ring to use this lens, it is recommended to use an adapter with a centerline adjustment function (picture below left).
Vignetting Test
The TTArtisan 250mm F5.6 is a full-frame lens and has no vignetting when used on APS-C or full-frame cameras. When used on medium format cameras, the faint vignetting makes the work more artistic.
