Summary: Must have lens for any serious architecture shooter. It's simply amazing how wide you can shift side to side or up and down for seamless panoramas. There's some vignetting and softness at the extreme edges but there's plenty you can capture without going to the edge. The fact you can focus down to 2" is an added benefit. Optics are top notch, as you'd expect for a $2k lens.
Summary: After purchasing all the top zoom lenses (14-24,24-70, and even a Nikon Edge85 for 2600mm of glory) I quickly realized the importance of glass in the elements as many do. Moving to a 35mm prime and a 85mm prime (1.4) I figured I had everything I needed for solid professional images. Occasionally pulling out the 14-24 for that super wide yet large focal plane - it works great for tight conditions and shooting the stars. Then I met the 24-pce.
Summary: Love this lens. Great clarity. I noted the advice about hitting the camera with it. I have so far not had a problem with that, but have had it slip when turned horizontally on my bracket. I'm careful not to tighten the screws too tight, don't want to strip them, but as a result, I have to watch it when turning the camera horizontally on the bracket. The clarity of the photos is so much better than my old lens, no comparison, and it's nice to be able to vary the f stops.
Summary: If you have a good copy of the 24 PC-E it sings on the D800. My copy is good. I wish Nikon would update their PC-E glass to the new Canon standards (the incredible 17 and new 24). This lens really does well with the D4 or D3x. Don't stop down below F/8 on a D800, otherwise you will get diffraction.
INDISPENSABLE LENS FOR LANDSCAPE & ARCHITECTURAL PHOTOGRAPHERS

Summary: Most I wanted to say here are already expressed. Maybe I can add. The lens is complex, very expensive, and Is It Worth It? The answer is absolutely 'YES'. The negative aspect is that it is hard and almost impossible to get clarity and razor-sharp images without a tripod. Because of that it makes the lens less versatile--as far as amount of supported-equipment needed to shoot scenes properly is concern. I wish the lens was both Manual and Auto Focus.
Useful for specific purposes, but marred by distortion

Summary: I bought this lens specifically for architecture project shoots. The lens performs well in that it is fast to use compared to the old 4x5 setup--you simply rotate the knob and the lens goes through the rise and fall range. Sharpness and quality are perfect in the center of the image but there is distinct barrel distortion (the buildings appear to bulge outward, or horizontal lines rise to the middle and fall to the outer edges).
Summary: The first thing that came in my mind when I first tried this wide angle tilt and shift after buying it: "why didn't I buy this lens before???" I always thought that these lenses were more appropriate in architectural photography, but they can do much more than that. For landscape, it is the perfect lens. First, its performances without using the tilt and shift are staggering. The sharpness and contrast are very impressive.
Summary: I waited a long time before I plunked down the 2k for this lens. I shoot a lot of architectural images and this lens has been on my wish list for quite a while. I have not been disappointed by the wonderful images that it has delivered. I don't mind it being all manual either - it makes me think about what I'm about to do. However, the little tiny thumb-screws used to unlock and tilt/shift the lens are way too small. I'm a big guy with big hands.
