Review on Pentax SMC DA Series 50-135mm f/2.8 ED IF SDM Telephoto Zoom Lens for Pentax DSLR Cameras: Enhance Your Photography by Bogomil Bogomilov ᠌

The picture quality is really impressive! And at all focal lengths. It seemed to me that the lens is most suitable for shooting portraits. Although I have used it very little so far. Different pros: Build quality. Aperture. Quiet focusing thanks to the ultrasonic motor. Cons: I would like a stronger zoom, on the other hand, there is an option for 60-250 from Pentax, though for slightly different money.
