Originally posted by janosh Using "A" lenses, do K70 et al somehow adjust more than shutter with some settings? Seems impossible...also seems to be real with my 28 "A" an 50 "A" macro.
When the aperture ring on a "A" lens is set to the "A" position, the aperture behaves like any more modern lens. It can be set with the e-dial in Manual or Bulb mode or X-SYNC. In Av or TAv mode it is also set with the e-dial and the camera will adjust the shutter speed or ISO accordingly. In Tv or P or AUTO mode the camera will set the aperture required for exposure.
Now if you take the ring off the "A" setting, you lose a lot of functionality. If you set the ring to any actual aperture setting, that aperture will only be used in Manual or Bulb or X-SYNC. In any other of the auto modes the camera reverts to Av mode but at maximum aperture only. So setting the ring to say f8 and the mode to P will give you Av mode at f2.8 on your 50mm Macro.

Originally posted by janosh I'm wondering if HDR setting (which produces multiple overlapping/interacting exposures) is doing multiple micro-focus between those multiple HDR exposures. Is that possible?
What is the problem you are seeing ?
When the camera combines multiple images for HDR it will use Auto-Align (unless you turn that off) to combine the images. If you are using a slow shutter speed or have things moving in the scene during HDR capture, this can lead to odd images which look like out of focus or double images.
