It's been a new lens double feature this week!
After having sold the DA 14mm 2.8 and Tamron 28-75mm 2.8, I picked up a new FA 77mm 1.8 Limited and a lovingly used DA* 16-50mm 2.8 (many thanks to MikeDubU).... I paid a total of $1060 for both lenses... about $600 of that came from the sale of the 14mm and Tamron.
I could not be happier! I have been dreaming of the 77 Limited since before I even had my first Pentax camera body. And, the 16-50 is going to be wonderfully versatile.
Here's my version of brick wall samples... all wide open...
16-50mm @ 1/100 sec, F/2.8, iso 400, 16mm
16-50mm @ 1/100 sec, F/2.8, iso 400, 50mm
77 Limited @ 1/50 sec, F/1.8, iso 100
77 Limited @ 1/80 sec, F/1.8, iso 400
