Why a K-3II over a K-70? Is it worth the extra cash? Let's see...
27 AF points versus 11.
25 cross-type AF points versus 9 points.
710 shots per battery versus 410.
Shutter Speed 1/8000 versus 1/6000.
Shutter life - the K-3II shutter is rated for 4X more actuations than the K-70.
Continuous shooting 8.3 frames per second versus 6.
Bigger RAW buffer 22 shots versus 11.
Memory card slots 2 versus 1.
Top LCD versus no top LCD.
K-3II has AF and AE buttons - K-70 uses one button for both functions.
K-3II has dedicated AE metering button while K-70 has to be accessed through the menu.
The K-3 II has dedicated auto-focus mode button used to switch between AF modes - on the K-70 it is done through the control panel or menu.
K-3II has a dedicated ISO button - on the K-70 this is done with the 4 way controller.
Rugged Magnesium alloy body versus polycarbonate - the K-3II can take a serious beating.
Short summary - the K-3II is a faster, more robust piece of equipment with superior AF and is highly customizable.
