Architectural Photography
For those of you who shoot architectural photography, I am looking to buy a medium format lense for this, and think I have narrowed it down to these; HCD28mm or HC35mm. Does anyone have working knowledge of these two? How important would the tilt and shift adapter be?
Thanks,
Greg

IMHO the tilt for these lenses is not so important. They are quite wide and wide angle lenses, when tilted, due to curvature of field,
exhibit quite a bit of lateral chromatic aberation, or color fringing which you later need to correct. DXo has some nice correction software which may help.
But because of the inherent depth of field of such short lenses you may not need the tilt. This need is increased though by the higher mp backs. You cannot stop down as far, for instance, with a P65+ or Leaf 56mp back as you can with a back around 30-33mp due to diffraction. You will lose at least a stop of depth of field and perhaps almost 2.

The HTS Tilt Shift adapter it's somewhat limited for those shooting architecture/interiors. 28mm, which is equivalent to approximately a 20mm on a 35mm; at 1.5x it's about a 30mm on a 35

The HC35 is sharp in the center but soft in the corners, regardless of f/stop. It does better at moderate and close distances than it does at infinity. The HC28 is sharp in the center and sharp at the edges at f/8. I'd get the HC28 and if you need to do perspective correction you'll have that much more in the picture to play with. The HC28 is a fine lens.
