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 Ada Szepelska ᠌

The only lens, after viewing the photos of which on the monitor, I did not want to correct the colors. Lowered the score due to slow autofocus and price. Pros: Picture, picture and picture again. Even on the screen of the camera you can see that the glass is thoroughbred and of high quality. Strong autofocus and accurate. Some cons: Unfortunately, this is a lens that not everyone can afford due to the price. Autofocus is slow, but as I understand it, you adapt to it.
