The TTArtisan A20B is a prime lens with a 50 mm focal length and a maximum aperture of f/1.2. Its Sonnar optical design, featuring 7 elements in 5 groups, contributes to sharpness, low distortion, and accurate image reproduction. Manual focus allows focusing from as close as 50 cm, while the 10-blade aperture creates smooth bokeh. The f/1.2 aperture provides...

  • Type

    Telephoto

    Telephoto lenses offer optical zoom that allows photography from a distance. Lenses with a focal length of 80-135mm on full frame, 50-75mm on crop frame, and 120-180mm on medium format are ideal for portrait photography as they allow photography from a medium distance and flatter the subject's features. Larger focal lengths are used for wildlife photography, sports events, and generally for all subjects that require a greater distance.

  • Mount

    The type of mount that the camera body must have in order for the lens to be fully functional when attached to it.

    2. Some lenses can be used with older mounts from the same manufacturer, sacrificing certain functions (e.g. autofocus), or even with mounts from other manufacturers using an adapter.

  • Item

    Lenses with variable optical (zoom) that remain equally bright (same maximum aperture value) throughout the entire focal distance range they offer. Usually significantly more expensive than their variable aperture counterparts.

    Fixed Focal Length

    Lenses with fixed optics are usually of higher quality than a corresponding zoom lens at the same focal distance. They are also called "fixed" or "prime" lenses.

  • Maximum Aperture (f)

    Opening the diaphragm determines the amount of light received by the camera and affects the depth of field.
    2. The most open aperture of a lens is called the maximum. The more open the aperture (smaller f-number), the shallower the depth of field.

Description

The TTArtisan A20B is a prime lens with a 50 mm focal length and a maximum aperture of f/1.2. Its Sonnar optical design, featuring 7 elements in 5 groups, contributes to sharpness, low distortion, and accurate image reproduction. Manual focus allows focusing from as close as 50 cm, while the 10-blade aperture creates smooth bokeh. The f/1.2 aperture provides control over depth of field and makes photography in low-light conditions easier.

It is the distance that the light rays need to travel to reach the focal point, that is, the lens sensor.
The smaller the focal distance, the larger the angle of view for the photograph and therefore the lens can capture more of what is in front of us.
