Macro, Wide Angle

Type

Macro

The lens has a macro function for photographing subjects from very close distances.

Wide Angle

Wide-angle lenses with optics that allow for fitting many elements within the frame with relatively little distortion. Their focal distance is usually 24-35mm for full-frame, 15-25mm for crop frame, and 50-70mm for medium format. They are commonly used in street photography but also in indoor spaces where there is limited distance from the subject. The perspective of wide-angle lenses makes things appear farther apart than they actually are.

Lens Type

Fixed Focal Length

Lens Type

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

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)

4

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)

32

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

77 mm

Filter Diameter

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

Focal Length

15 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.

Weight

410 gr

Mount

Pentax K

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.

Features & Functions

Image Stabilization

No

Image Stabilization

The lens features image stabilization function for clearer photos and videos when shooting handheld, especially in low light conditions.

Autofocus (AF)

No

Autofocus (AF)

The lens has an automatic focusing function. Particularly useful for photographing subjects in motion (e.g. children playing).

3D

No

3D

Lenses for creating stereoscopic images.
