Looks like every post in this thread try to keep you with pentax - so me too ;-) Also seems like the thread is off-track a bit.
Originally posted by Framed I do mainly portraits so I'm after a fast lens for the bokeh. Love me some bokeh. ) Low light is one of the reason I want to upgrade my body but even so, I love shooting wide open.
I do portrait most of the time, bokeh is a must. I m using k20, umbrella and my lens for portrait is da*50-135.
The aperture does not be wide open all time, but should not be smaller than f4. By planning distance to subject and distance to background, I get the bokeh I want. For a typical living room with some open space like the entry or kitchen, when distance subject-background>3m/10feet and distance to subject>2m/6feet, the bokeh is just perfect. I don't really care which pentax body I use, as long as the light is good and I can keep the safe distance for DOF portraiture.
Give the lens a try. Let me know if you need sample image.
Best regards.
