www.dpreview.com states as qouted below, that the AF is rather slow, you
must push down the biult-in flash maunally (AF assist) before takeing the
picture, if yoy don't want ti use flash light, and that the AF assist light
may require more than one attempt before focus lock is achieved.
Is this really the case? If so, not very flattering, is it?
AF in *istD is slow below certain light level. Mostly due to its smaller AF sensors size - they are about 2x smaller than the ones in MZ-S and catch less light. When compared to MZ-S with identical lens, MZ-S is about 2x faster in low light. The only solution would be to double AF sensors - one set for low light and the other for higher light levels - exactly as it is made in Nikon F100 known quite well for its good AF speed in low light. But in good light I feel that *istD AF catches much more easily than any older Pentax AF camera on almost everything, probably thanks to cross type sensors sensitive to both - horizontal and vertical lines. Another plus for the newest Safox in *istD is that it doesn't suffer from infinity bug found in MZ-S - when you focus fast lenses in infinity it really sets infinity in lens, not "almost" infinity like MZ-S does (I tested and confirmed it with FA 35/2, FA 50/1.7 and FA 100/2.8).
On low light, force center sensor only, it's the more sensitive.
