[Leica] Big SL Lens ( DIameter) explanation

[mark at rabinergroup.com (Mark Rabiner)]

I just did a project my first in years and I guess I became less casual about my shooting as I turned off the AF for a third of the shots a reason being my focus was certainly not in the very center of the shot but way off somewhere and I needed to control it fluidly just like the old days of manual focus.
I used to say I don?t need auto focus I am  auto focus. But I do love auto focus. Though in a way it makes you stupid and makes your shots stupid with an emphasis on centering you subject.
And I could get better in shifting the auto focus but you know what? It may not be possible are even preferable.
I think for some stuff turn the AF off.  Go with the Force.

    This was from a couple of years ago so I don't remember every last
    detail... but I think the deal was that while I really liked the way
    pictures with these fast manual-focus lenses could look, working with
    them was a bunch slower than nipping in with the autofocus zoom and
    just magically getting the picture.  So people seemed to feel my
    presence and the camera's gaze more when I was fussing with manual
    focus, and it ended up affecting the pictures.  This made me gravitate
    to mostly using the SL autofocus lens.
    
    I think one issue was that I didn't usually want to compose with the
    most important in-focus thing right on the middle of the frame, so I'd
    move the magnified area over to the part of the picture where the Most
    Important Thing (usually somebody's eyes) was and then focus.  I don't
    think I trusted the full-frame focus peaking display as much as I
    trusted seeing sharp focus at maximum magnification.  But anyway, this
    was fiddlier than just maybe putting the autofocus hotspot in the
    right place before sliding into position then bing! getting the
    picture.
    
    Of course, just always focusing the middle of the frame can be made to
    work - when using that still-quite-nice Canon 85mm f/1.2, the only way
    I got reliable good focus on a 5D Mk II body was to always focus with
    the middle AF point.  So I just backed up and composed assuming I'd
    crop to the composition I wanted later.  But I never liked throwing
    away that many of the pixels.
