A recent thread here on a Schneider Tilt-shift lens made me remember how I used to love using a shift lens. Long time ago I hesitated a few years to buy a PC-Nikkor 35/2.8 for my F3 and then I used it all the time. And then I agonized again for a few years over the purchase of a PC-Nikkor 28. Again I bought one and sure enough used it all the time. Sadly, the shift lenses disappointed on the D200 in terms of image quality and I sold them off; could'nt see myself using film anymore. I think I'm done living without a shift lens. The MFT lens line-up won't probably offer one for many years to come, so knowing myself I'm going to end up someday with a Canon 24mm T/S L II and probably a 5D Mark II. The 17mm T/S is more attractive, about 27mm eq. on a Canon APS-C body, but is optically not quite as good as the 24 T/S and has a very vulnerable front element. And according to test pics the Nikkor PC-E 24 is clearly inferior in terms of distortion and CA. This would be a return to a DSLR with all its focussing problems, but fortunately live-view can come to the rescue here for tripod work with a shift lens. And it would be my first ever Canon gear. That said I won't give up MFT gear, it's simply too good to do without.
