  • 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.

  • Sensor Type

    Full Frame

    Photographic lenses designed for use on full frame sensor cameras. A full frame lens can also be used on a crop frame sensor camera, but with its focal length adjusted according to the corresponding crop factor.

    For example, a full frame lens with a focal length of 50mm (standard) on a camera body with a crop factor of 1.6 will function with a perspective as if it were an 80mm lens (telephoto).

    The reverse does not work as the optics of a crop frame lens are not sufficient to cover an entire full frame sensor, resulting in the edges of the frame being black (severe vignetting).

  • 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.

Full Frame

Photographic lenses designed for use on full frame sensor cameras. A full frame lens can also be used on a crop frame sensor camera, but with its focal length adjusted according to the corresponding crop factor.

The reverse does not work as the optics of a crop frame lens are not sufficient to cover an entire full frame sensor, resulting in the edges of the frame being black (severe vignetting).
Maximum Aperture (f)
2

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.
Minimum Aperture (f)
22

Minimum Aperture (f)

Opening the diaphragm determines the amount of light received by the camera and affects the depth of field.

2. The smallest diameter of the diaphragm is the minimum value. The more closed the diaphragm (larger f-number), the greater the depth of field.
Filter Diameter
67 mm

Filter Diameter

The diameter that a filter must have to be applied on the lens without the use of an adapter.
Focal Length
105 mm

Focal Length

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.
