Quote from: Telecaster on October 07, 2017, 03:45:00 pmI find peaking effective with subjects facing at an angle to you, so you can see the focus zone move across the subject as you turn your lens' focus ring. Peaking is much less of a help when you're facing the subject straight on.

Quote from: biker on October 16, 2017, 02:14:26 pmNot sure about Sony and ML but my Pentax DSLR keeps the aperture fully open regardless on what you set on the aperture ring. The only moment when the aperture setting is applied - is the moment of the shot. Why couldn't they do the same with a ML camera?
Quote from: pegelli on October 16, 2017, 02:36:36 pmOn my mirrorless cameras I think it's an option, you either AF full open or AF at the set aperture based on how you set it (with native AF lenses). Advantage of AF closed down is that it reduces shutter lag and avoids focus shift. AF fully open might be more accurate (if the lens has no focus shift). CDAF (and on-sensor PDAF) of mirrorless cameras are sufficiently accurate to focus while stopped down.DSLR's with separate PDAF sensors have no other option, because that system just doen't work when closed further than f5.6.
Quote from: biker on October 16, 2017, 02:57:36 pmInteresting - thanks! The shutter lag isn't a big problem for me but the focus shift issue didn't come to my mind.But why f/5.6? With focal lengths like 200mm or more the DOF is still pretty shallow even with higher f-numbers.
