Proving the DSLR is still a highly capable tool, the Pentax K-3 Mark III marries contemporary imaging capabilities with the trusty and familiar design of an SLR. Taking the flagship spot in Pentax's APS-C lineup, the K-3 Mark III is characterized by a new 25.7MP BSI CMOS sensor, a high-density 101-point AF system, a revised pentaprism optical viewfinder, and an advanced SR II Shake Reduction System. As a Pentax, too, the K-3 Mark III is also distinguished by its robust physical construction and extensive weather sealing for working in harsh weather conditions and climates.

Will there be cropping with DA lenses?
Will there be cropping with DA lenses?
Pentax DA lenses have an image circle size tailored to the APS-C image sensor size, which is smaller -- about 43% of the area -- than the full-frame image sensor size. This camera has an APS-C image sensor. So no, it won't be cropped with DA lenses; it has the image size intended for DA lenses.
Now if you use a full-frame lens on it, then yes, that would be cropped -- 1.5 crop factor -- as expected, just like all of Pentax's previous APS-C DSLRs.
That said, you would still use the 1.5 crop factor on any lens, DA or otherwise, to know what the lens' field of view will be on this camera. For example, a 50mm lens, whether DA or full-frame, will have the field of view on this camera that a 75mm lens has on full-frame cameras.

Are my lenses from my K-5 compatible with the K-3?
Yes, the K-3 iii should be compatible with every K-mount lens ever made, going all the way back to the very first K-mount lenses made in 1975. If a lens works on your K-5, it should work on the K-3 iii.
As with all previous Pentax DSLRs, there is a special step to get a meter reading with old lenses that don't have an "A" setting on their aperture ring. Most of these lenses are 1970s & 80s vintage. Apparently the K-3 iii has even better compatibility with those old lenses than previous Pentax DSLRS. See:
