Nikkor 35mm f3.5 PC
PC or 'perspective control' lenses are handy for architectural shots or tree filled landscapes. I recently discovered that they are also very good for normal shooting and close up work. My copy of this lens is from the mid 1960's.
It focuses down to 9" and at close range it is sharp wide open and tack sharp from f5.6.
Bokeh has a smooth dissolve; slightly smoother than standard Nikkors.
Contrast is high which is expected from an architectural lens.
Color rendition is excellent in even lighting. Backligthing and harsh lighting causes clipping in highlights and some chromatic abberations. Purple fringing is noticeable but not complex. Bokeh fringing is subtle but can be seen in highlights.
On theT2i it is not as awkward as I assumed but not without its quirks. The shift mechanism has room to slide and rotate. It is possible to use aperture priority when the lens isn't shifted but you must use manual exposure when it's shifted. Focusing is precise and well dampened.
