I like my Pentax FA 77mm f/1.8 limited a lot. The DA 70mm f/2.4 is a great lens but I spend a bit more just to get the gain of aperture speed. I call 77mm limited
insanely good in my blog when I first tried it and it has the best color and sharpness in my lens for portrait. And it is fast and I use it wide open at night event and I can count on it. I have the
silver version. All test shots hand-held with K20D in jpg.
