It's the same process, sure. But there's a huge difference in the actual experience. A MF lens has usually a focus ring that turns at least half a revolution, maybe 3/4, whereas the ring on an AF lens turns only a small amount. So with an AF lens, a tiny motion of the ring changes focus a lot, making it very hard to focus precisely Plus they are so loose that is hard to turn the ring precisely. Whereas with an MF lens, the ring offers much more resistance, making it easier to control the movement, and small movements of the ring affect focus only small amounts, making it much easier to fine tune the focus.

I can't speak for him, but I would say AF is accurate *if* it happens to guess right and focus exactly where you wanted. But even if you select a focus point yourself, that's not really a "point" but a "general area", and if you really want pinpoint the location of the focus, AF is not the best tool. Also, on cameras pther than the K-7, tungsten or other yellow/orange light will cause the camera to front focus. I pretty routinely turn off the AF when shooting in low light with large aperture / small DOF, as even with this lens and it's so-so focus ring, I can place focus more precisely by doing it myself than by hoping the camera will place it exactly where I want.
Quote: MF user do you have to magnifying eyepiece when shooting MF or it can be done w/out?
It *can* be done without, but sure, the bigger the better, within reason. The cameras that have smaller viewfinders (eg, K-x, K-m, KxxxD) may benefit from a magnifier more than the ones with the larger viewfinders (K-7, KxxD).
