Juts been playing with the k3 in low light it will focus 4sec f2.8 iso3200 !! I can't even see what it focusing on till I take the shot.

I'm finding the same - if I can see it, then with the right lens I can probably focus on it. Liberating!

Think I may need to re-asses my lens as well

Was playing what's fastest in moderate low light and to my surprise point to point 5ft -20ft my da*55 was quickest followed by the da* 16-50 !

My quick lens the da* 300 was 3rd and 50-135 4th with my 'controls' da 18-55 (nicked wives off KX) and Sigma 70-300 Apo seriously sluggish.

I suspect it's T-stop related, Besides the Sigma which seems to have a bug every time I went short to long the lens focused shorter - long !
