Being an architect (finishing up my license exams as we speak), photography is only second to architecture as my passion. I am all around it daily and live in the perfect location for it: New York City. Most of what others have said are true about the distortion and converging lines. It's hard to control and leaving lots of space around main focus of image is a must.
Honestly I am just now seriously (hobbist & some documentary work for my firm) getting into architectural photography. You can see my sig for the lenses I have. Have not really tested and fully shot the k 28mm shift since I got it a few months ago. Looking forward to doing so next month or so. Just ordered a da* 50-135. Will utilize this for details and partial shots. Sold my Tamron 10-24. Will get a sigma UWA soon.
A poor attempt was this set. Was definitely learning and used my kit 18-55mm lens at the time. Needs to be edited and straightened:

A more recent attempt came out better but I am still very critical of myself and look to improve. Distortion got the best of me on bldg sides and had to stretch a lot to straighten lines. Final images weren't what I wanted.
