I use this as most which is to say for architecture and landscapes however for more and more of my wedding shoots I'm using this as a on location portraiture lens with RAVE reviews. Sometimes using a tool not intended for the operation at hand creates a happy accident and such was the case for me. Now it is right next to my 85 1.2 Mk II for portraiture and I really do mean that. I highly commend this lens for creative and technical shooting.

It tilts and it shifts. And you get the pictures tilted and shifted. But there are a few things you might need to know before buying it: 1 - The lens is built to tilt in one direction and shift perpendicular to that direction. You will not be able to tilt and shift in the same direction, unless you hack it (unscrew four screws, twist the bottom and, fit in the wires, screw the four screws back I don't have the stomach to do it, if you do, go for it). 2 It tilts and shifts, but also rotates. 3 Pretty hard to focus, especially if you don't have liveview. 4 The user manual only explains how to operate the lens, but it is not very thorough when explaining what effects you might get 5 Be patient with it: the learning curve might be slow, but the results you get are beautiful, at least. I am having a great time unveiling the powers of this lens. Just it was a reason good enough for buying it.

This is the best lens in the market for photographing large buildings as you get a very wide coverage on 24mm using a full frame sensor like on the 5d mark ii and are able to correct perspective issues using the shift function. If you want to shoot miniature worlds this is not the lens to use thought as you will not get the effect on a wide angle lens. If you want to do that you're better with the 90mm or 45mm versions.

I buy this lens for Architecture / Interior photography. Build quality is great, not too heavy. Tilt and Shift very precise. The pictures also very sharp and clear. Manual focus ring smooth. Recommend to use grid focusing screen. I use this lens with full frame 5DII it's perfect match. It's OK for handheld if you don't do much Tilt or Shift.
