عدسة زووم Sigma 28-70mm f/3.5-4.5 UC AF لكاميرات Pentax-K و Ricoh XR-P

I’ve been using this 28-70mm zoom on my Pentax SLR, and the autofocus is snappy enough for street shooting. The six-bladed aperture gives a nice, smooth out-of-focus background in portraits, which I wasn’t expecting from a lens at this price point.

The compact size of this 28-70mm zoom is a huge plus for travel—it barely adds weight to my camera bag, and the six-blade aperture creates pleasing bokeh for portraits. Sharpness across the frame has impressed me, especially at the wider end.

Autofocus is snappy on my Pentax body, and the 6-bladed aperture gives bokeh that’s pleasantly soft without being distracting. It’s compact enough that I don’t mind carrying it daily, though I wish the max aperture opened a bit wider for low light.
