Originally posted by WillWeaverRVA Not even the K-3 has a KAF3 mount; the entry-level K-S1 and midrange K-S2 have KAF2 mounts, as well. I wouldn't worry about the full frame camera having one.
I think some people is actually drowning without even getting their feet wet.
The so feared KAF3 mount is a "lens" designation and as of now, not a body spec designation. The K3 body is KAF2, but compatible with KAF3 lenses (see page 90 in K3 owner's manual)
Another detail that seems some people is struggling and debating over the new FF body specs, is about the speculations published at pentaxeros web page, which is nothing more than a copy/paste from the actual K3 specs.
According to page 81 in K3' manual, the difference between KAF2 and KAF3, is the lack of AF coupler (worm drive) like on newer DA glass like the 18-135, 16-85 and the recently annonced pro level big FF zooms or the new entry level kit zoom.
The most recent lens roadmap still shows some worm drive only glass, like the 12-24 zoom, the limiteds, the FA50 /1.4 and others that it would br a big mistake from Ricoh if the new FF body cannot autofocus them.
BTW the biggest difference between DA and FA glass, is that only the DA (and its variations like DFA, DAF) transmit the lens correction data (distorsion, CA, PF and diffraction) to the body like the K3 or new FF body, a feature probably not valued yet as it should, that may well push legacy glass owners towards new glass purchases.
CP+ is just a day away, but sadly enough, I don't believe we'll get full specs disclosure for the new FF body; probably not even the name/ code designation.
Let's hope and see. We got digital 15 yrs ago. FF is still in the womb but at least we know the stork has taken off and flying for safe delivery. Unfortunately, our baby could be an elephant (more than a year pregnancy), even though we would like our stork to fly like a falcon delivering hamsters.
So guys, lets keep doing what our beloved passion (Pentax) has made us undisputable masters: KEEP WAITING for a few months more. I am sure we are all going to be rewarded for our "Tibethian" patience.
