gordon lafleur: TS lenses, especially wide angle one, are redundant in the digital age. Photoshop does an admiral job of correcting converging verticals, and what the heck would you use tilt for on a 24mm.
Good question. How about a composition with flowers in the foreground inches away, and a mountain in the background at infinity. Given the sharpness falloff toward the outside of the image circle of a tilted lens, and given the sharpness falloff due to diffraction at small apertures, would one get a sharper image shooting this composition flat with a sharp 24mm prime lens at f/16 or f/22, or shooting with the TS lens at f/8 with focal plane tilted through both flowers and mountain?
