Craig:
Nikon shooters are kind of stuck. I think they only make one pc lens. A 45 or so? Not really very wide.

Not quite true. Nikon has 85mm and 28mm PC lenses.

I think the 85 is the only one they make. 28mm not listed anymore on Nikons site and B&H does say they don't know when they will get them. Looks like never.

Thanks, Craig. I did not realize that the 28mm PC lens has been discontinued.

You might want to look at the used market for a PC lens. Nikon manufactured both a 28mm PC and a 35mm PC in the past. I understand that the 85mm is the only one currently in production, and it's a tilt/shift lens like the Canon TS-E lenses. eBay has numerous listings for both the 28mm and 35mm Nikon PC lenses.

I too, have been contemplating moving from my prized Sinar camera systems to Canon. I have been a die-hard Nikon shooter for the last 25 years. As far as I know, Canon is the ONLY company making the full frame DSLR's today. I have heard many rumors about a Nikon "D3" in the not so distance future that's a full frame sensor system, but for now, looks like I'm switching gears. Also, Nikon's logic escapes me; why would they make an 85mm PC shift lens? What does it accomplish? Why did they discontinue the wildly popular 28mm PC shift lens? Of course, being an architectural photography, Nikon's form factor of 1.5x kills wide angle lenses, at least in my opinion. So their 28mm becomes a 42mm equivelant? Useless when shooting interiors and wide spaces...

Full sensor?
Its getting older by the day but don't forget the Kodak 14N, largely unnoticed because a] its no longer supported by Kodak and b] its slower than Heintz Catsup on a winter morning but, with still lifes, it give a beautiful 14 megapixel image in RAW and takes your best Nikon lenses.

hope this is helpful
