Pentax DA 50mm f/1.8 Reviews

Fantastic Plastic 50

By Nora

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.

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

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
