Manufacturer description

TTArtisan 250mm F5.6 Reflex is a compact telephoto manual lens. Due to the characteristics of its catadioptric design, the weight and size can be well controlled.

The 250mm focal length allows the photographer to capture clear and vivid images without getting close to the subjects.

Telephoto lens compression is a visual effect where the foreground and background in an image appear closer than they are.

The reflectivity of light in a reflex lens plays a crucial role in the final image, and the TTArtisan 250mm F5.6 Reflex uses a metal mirror structure with a reflectivity of up to 98% to reduce the attenuation of light after two reflections.

Use the TTArtisan 250mm F5.6 reflex lens to create a dreamy and special donut bokeh. This special bokeh combined with rich colors creates a unique imaging style that is very attractive.

Doughnut bokeh is a great artistic addition to add some liveliness and creativity to portraits.

Due to the characteristics of its optical design,the lens is not only small and lightweight, but can also effectively control chromatic aberration and achieve excellent image quality. Using this lens to shoot flower subjects can produce images with rich colors and as beautiful as oil paintings.

The unique bokeh allows this lens to present a different image style from conventional lenses when shooting various subjects, and can add a lot of fun to an ordinary scene.

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.

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.

It is designed for the M42-mount. But with an adapter, the lens is compatible with Sony, Fujifilm, Canon, Nikon and other cameras.

Because of the special optical design of the reflex lens, it is lighter and smaller than the conventional lens of the same specification.

Typical characteristics of mirror (reflex) lenses

• Catadioptric system consisting of curved mirrors and optical glass;
• Much shorter, lighter and less expensive designs than conventional super telephoto lenses;
• Outstanding correction of chromatic aberrations;
• Since the aperture is fixed, neutral density filters are used to obtain a smaller aperture;
• Doughnut-shaped out-of-focus highlights.
