  • Type

    Standard

    The visual they offer is very close to the human eye and is often called "normal". They provide a natural result with minimal distortions and their focal distance is usually 40-55mm in full frame, 25-40mm in crop frame, and 80-100mm in medium format.

  • 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.

Description

Description

The Pentax smc DA 50mm f/1.8 lens is a fixed focal length lens, specifically designed for Pentax DSLR cameras that accept the K-mount lens series. It features a very bright f1.8 aperture that makes it possible to shoot in low light conditions, offers a focal length of 76.5mm, and is considered ideal for portraits as it produces pleasant bokeh in the out-of-focus areas of a photo.

The lens is lightweight (122g) and small (3.8 cm) and features Pentax Super Protect (SP) coating that repels dust, water, and grease/oil from the lens surface, making the lens easier to clean externally.

Technical Specifications

  • Focal Length: 50 mm
  • Maximum Aperture: f/1.8
  • Minimum Aperture: f/22
  • Angle of View: 31.5°
  • Lens Construction: 6 elements in 5 groups
  • Minimum Focusing Distance: 45.11 cm
  • Filter Size: 52 mm
  • Lens Hood: Yes
  • Dimensions: Approximately 6.35 x 3.81 cm
  • Weight: 122 gr

    Lightweight, perfect image quality, good bokeh, relatively fast AF, lightweight, excellent price. It makes noise but I don't consider it a negative aspect.
