"With this tilt-shift lens you can make miniture time lapse, or pictures. The 9 bladed design creates stunning bokeh."

They don't tilt or swing as much as a large format camera, of course, but offer a nice alternative for the digital shooter of architecture and products.

liked most - flat perspective liked least - need for tripod

Have used this lens in conjuction with D800E documenting changes in a landfill for the last 7 years, stiching picture together up to 4 GB (consisting of over 40 individual photos at mulitiple levels). Easy to index, very sharp impages. Perspective control prevents distortion.
