Originally posted by reh321 My belief is that Pentax is going to redirect their APS-C efforts more towards "event" photography, leaving "landscape" photography primarily to the FF line. In order to lure users away from other brands which need not be named here, they will need more reliable AF and better high ISO results. Just as the K-3ii was a small step up from the K-3, but provided testing of new concepts for the K-1, I believe the K-70 will provide testing of new {to Pentax} concepts for more expensive members of the APS-C line, and the K-70 will be a genuine success if it does lead to an improvement in those areas for the APS-C line, and the K-70 may seriously out-perform the older {but more expensive} members of the line in those areas if the new technologies do prove their worth.
Using the OVF, the main sensor don't see the scene so like any DSLR before it it would have to rely on the dedicated PDAF and metering modules to perform AF and tracking as well as metering.
The K70 has same hardware as KS2 (or K5): 11 point AF module and 77B&W metering. It is impossible to do any tracking with that, the camera doesn't see an image but a few area with different shade of gray and the off center AF point are huge.
The difference come fom the main sensor that can provide for metering, tracking and PDAF. The sensor see the scene when the mirror is up only, So either you shoot in LV, eiter it isn't going to happen.
The next APSC flagship will likely be build uppon K1 technology, hopefully with some improvement factored in in key areas but while K70 may pave the way for a Pentax mirrorless it isn't going to provide any significant edge toward still shooting AF vs a KS2 and will remain a few steps backward old K3 except maybe for LV.
The specs are here, there no reason to think something will magically happen while the hardware is clearly not capable of it.
