I have been pouring over books and reviews online and I can't seem to gather a concensus of lenses that are best for architectural photography. What are my options? PC lenses, wide angle, super wide angle? 28mm, 17-55mm? Thanks.

For exterior architectural photography a Perspective Correction lens is desirable. If you use a standard wide angle lens you'll get that "tilting/falling back" effect where the building appears to get narrower at the top. For interior architectural photography you'll need a wide angle that is rectilinear - lines at the edges should look like this I I, not this ( ). A tripod is recommended indoor and out.

A "perspective correction lens" means the TS-E 24mm Canon (or better) - and you will want to use it on a full frame camera with Photoshop CS3.
