an all plastic (ala 50 1.8, or 35 2.4) 31mm 1.8 would be easy enough to make and release with the camera...

but a 24-80 f4 ff zoom could appear as well....

the rumours are ALWAYS riddles with truth and half truth.... for every true fact there is an entourage of lies.
I'd say it is fact that the FF camera is in that price range....

here's some evidence to back up my theory..

by giving discounts on the FF lenses and recent adopters of the k5-II won't be as put off as they might be when the FF body comes out...

it's people lacking in integrity, morality or honesty that are the real problem, not the tools they use to decieve.

I'm speculating the following...
one new 645-d
one FF d-slr (two versions like the new k-5II)
one non WR model (stripped down k-30- in hundreds of colors)
one evf equipped k-01 replacement.

the constant aperture and respectable image quality make the 16-45 lens a HUGE bargain for studio shooters and those that prefer to shoot on "Manual"...

nobody likes having to recalculate the exposure every time you change the zoom....

then I suggest you learn to do the B&W conversion in post using lightroom or aperture....
you can create incredible shots from your raw files and will never envy Lieca again.

came up a lil short on video shooters needs... but the price? wow... a lot of camera for the buck...
now if version 2.0 comes along and they address a few little issues it would still be worth paying k-30 prices for...
Pentax should take a long look into improving video (ie 4k) as well as video af, and live raw hdmi output during recording, dual cardslots with simultanious recording of stills to one card and video to the other card......
and an accessory hdmi finder or external monitor.

pentax... a new or duo core processor would make it all possible..

adhd, dyslexia, dyscalculia, aspergers.

it sounds to me like it crops at the sensor then applies an algorithm to to bring the "resolution" back up to 10 mp...
