Just wanted to add my 2 cents on manual focusing legacy glass.
i had the k-01, and while focus peaking was...ok, i still missed action shots with legacy glass. and the lack of viewfinder in the sun (quite bright here in australia, and i didnt want to use a hood or loupe as....well, they look a bit odd haha) so i ended up selling it and not thinking anything of it. Then i read online that the k5, k30 etc etc, have focus confirm like nikon (silly me for not looking into that earlier).
So I picked up a k-30 yesterday at a great price (my first pentax dslr, used canon in the past) and WOW. what a difference having focus confirm makes! i can hold lenses super steady with the camera pressed against my face, and get into an easy, focus, green button, shoot routine. and it has made a MASSIVE difference. tested it out with my 28, 50, and 135. and i am returning a 100% in focus hit rate. im in love with this camera! its an absolute JOY to use.
rant over.
