The smc DA 50mm f/1.8 Lens from Pentax is a fast f/1.8 lens for cameras with a Pentax K mount. Mounted to a camera with an APS-C sensor, this lens gives an angle of view equivalent to a 76.5mm telephoto lens--ideal for portraits. The wide f/1.8 aperture makes this an essential lens for working in low light, and it also delivers beautiful bokeh (the out-of-focus portion of a photograph). This lightweight (4.3 oz) lens is very compact--just 1.5" (3.8 cm) long. The addition of Pentax Super Protect (SP) coating to the lens helps prevent dust, water, grease and other substances from attaching themselves to a lens and degrading image quality.
- Very Fast f/1.8 Maximum Aperture
- Excellent Low-Light Lens
- Pleasing Bokeh (Out-of-Focus Areas)
- SP Coating Repels Dust, Water, Grease

Pentax DA 50mm f/1.8 Reviews
Fantastic Plastic 50
This 50mm lens is as nice as all the other 50mm lens that I won: Canon's nifth fifty, Fujifilm 50mm, and Nikon's 50mm. The 50mm lens is just a great go-to lens for street photography and portraits.
Pentax 50mm
compact and sharp, great for street photography.
Lightweight, compact and arrived in perfect condition!
Very versatile lens that arrived safely in great condition.
Great Short Focus Lens with Blur
This lens has given me the option of taking great photos with blur. I will now be able to take wonderful portrait photos that have been difficult with my 18-270mm Pentax zoom lens. I was recommended this lens by your sales staff when I outlined what I wanted to achieve and have been very impressed with the service and short delivery time frame. I have attached my first photo of my kids money pig as an example
Super Sharp!
Calibrated lens to KP body first! Lens exceeds my expectations! Unbelievable for the price! Definitely recommend!
Wonderful, sharp photos
So far, I am thrilled with this lens! I am a beginner, but this produces wonderfully sharp images with a fabulous bokeh. I am very pleased with this purchase!
Nifty Fifty
Proper street lens for low light situations. Price can be beat. After going with three different mirrorless systems over the last 7 years, I've gone back to Pentax which doesn't manufacture mirrorless cameras. No gimmicks. Just a good basic lightweight lens for walkabout.
Great lens
This is a great little lens and is become on of my favorites that I use everyday.
