Pentax 50mm f1.8 DA Lens

The Pentax-DA 50mm f/1.8 Lens is a fast, prime, lightweight lens designed exclusively for Pentax K-Mount digital cameras. This lens features a large maximum aperture of f/1.8 and a round diaphragm to ensure a natural, beautiful bokeh (out of focus) effect, making it ideal for portraits and snapshots. Thanks to its large aperture, the lens allows for faster shutter speeds and offers superb handheld, low-light performance with no blur or noise. The front of the lens is equipped with SP (Super Protect) Coating to repel dust, water and grease from the surface of the lens.

Key Features

High-quality image description

Thanks to state-of-the-art PENTAX optical design technology, the image circle of the lens has been optimised for K-mount interchangeable-lens digital cameras to effectively counter astigmatism for sharp, clear images.

Easy-to-handle medium-telephoto lens

When mounted on a PENTAX K-mount interchangeable-lens digital camera body, this medium-telephoto lens offers a focal length of approximately 76.5mm in the 35mm format. This gives the user a moderate-telephoto perspective, perfect for portrait photography with a smooth, beautiful bokeh effect in the background. The exterior surface is treated with the PENTAX-original SP (Super Protect) Coating to not only repel dust, water and grease, but also to allow the easy removal of grease from the surface. This ensures worry-free shooting in any situation.

F1.8 maximum aperture

Thanks to its large F1.8 maximum aperture, the lens can easily produce images with a very shallow depth of field. Its round diaphragm produces a natural, beautiful bokeh effect, while minimising streaking of point light sources. The large aperture also makes it possible to use faster shutter speeds under poor lighting conditions to minimise the risk of camera and subject shake.

Compact, lightweight design

Measuring just 38.5 millimetres in length and weighing only 122 grams, this lens has a compact, lightweight design making it easy to carry along on any photography trip.
