I shot a wedding and struggled with the fact that my tall bride (6'2") could NOT have the focus point (shooting single point AFC - focus point her far eye) on her eye and have the frame (vertical & worse horizontal) from head to toe (outdoor wedding in confined Japanese Garden space). Used 24-85mm VR due to plenty of light outdoors.
This got WORSE (of course) indoors using 50mm 1.4G (low light - KUDOS to D600 here - shot at ISO 3200 and occasionally higher up to ISO 6400 as DJ lowered lights for dancing). It was very hard (for me - YMMV) to "foot zoom", pan with shallow DOF (shot lots at f2 or f2.2), and focus and recompose, so I lost some nice shots to lack of optimum focus (have not yet been to LR4 - maybe I can save some).
What did I learn? YES - I do wish the outer focus point could be moved "higher" in the frame with the joy stick (both vertically and horizontally - AKA landscape or portrait), especially in tight places and with 50mm prime. This likely would be true as well for lower placement of focus point shooting animals low in a frame in landscape shooting, or BIF low to water. I'd want to move the focus point lower.
Also: I think that the 50mm 1.4G is a sharper lens than the DX 35mm 1.8 I shot in FX mode wide open. This could be DOF, as I had the same focus point issue and when recomposing at such shallow DOF sharpness suffers. On a BRIGHT NOTE: in camera vignette control on HIGH works on JPEGS with this lens stopped to f1.8 to f2 (shot RAW + JPEG fine - have not done post yet).
