Originally posted by mtl_pentaxian Going back one generation, we can be fairly sure that K-S2 aperture control is more reliable than K-30/50 aperture control was - so most likely that will be true of the K-70 also - but the K-S2 and K-70 are still consumer grade cameras, so like any consumer grade camera, be it Canon Rebel, Nikon D3xxx, or any other comparable camera, most likely
something will fail while a higher-grade body is still running. In the case of the K-70, the something that fails may still be the aperture control, which still leaves the camera usable {unlike my Canon Rebels that had processor issues .... which makes the whole thing useless}
