Summary: Its sharp and the built quality is solid. I often take this guy with me on mountain adventures to add a twist to otherwise normal mountain landscapes. Its made of metal and all of the knobs have held up to some tough treatment. The 45mm focal length is great for what I want. Some may want wider...
Great focal length, good build, a optics a little soft

Summary: As others have stated, it's hard to focus to infinity when not tilting at all... it is odd, you'd think they would've made it so it could focus beyond infinity, like most lenses, but it stops just short of infinity. Lens is a little disappointedly sharp at 2.8 and not much cleaner till 5.6 or so... but honestly, it's a tilt shift. It's mostly for fun for me and I don't expect it to be as sharp as an 85mm 1.2 or anything. I will say the focal length is very usable.
Excellent lens ONLY if you know you're going to tilt and/or shift often. If not, this may not be that useful in other situation

Summary: If you're looking at reviews for this lens you may already know what it is capable of doing and are wondering how users feel about it after purchasing. For me, I bought this lens for its main dual purposes - shifting the focal plane to get the trendy "tilt-shift" blur effect, and to make taking panoramic shots more simple using the shift feature. This lens is solidly built and tack sharp wide open.
Summary: It is a nice, sharp lens but know this: there's a steep learning curve. Not something you can pick up and shoot with and get any consistently good results. It's manual focus. I tried manually focusing it through the viewfinder of a full-frame camera, using the stock focusing screen, and NONE of the shots came out in focus. Don't get this if your camera doesn't allow you to change to a better focusing screen unless you're going to use Liveview on the LCD.
Summary: I have to get this off my chest in response to the 'too bad it's a manual focus only lens' review. ALL tilt shifts are manual focus because it's impossible for the camera to focus with one! [when the focal plane is tilted or shifted at least]. I've got a canon CPS demo of this lens and it's been nothing short of what I expected. Very sharp at 2.8, and the creative possibilities are amazing.
Summary: I bought this for my son, well, we bought it together for his photography business. He has only been able to borrow this lens on photo shoots before this purchase. He lives in a different state than I do and although we talk almost every day, each conversation now has something great to say about this lens. It has definetly put his creativity into a bigger category.
Summary: The possibility's are enormous if you know how to use the lens, it is not so very easy to learn. I like the 45 mm on a FF very much, just in the middle of my two favourite's , the 35 mm and the 50/55 mm. It is easy to create miniature with this lens. Portraits also nice, but you will not use that very often. Canon says that it is not possible to use extenders, that is not true. I do not know why they say that.
Pros: Offcourse all the nice things you can do with a tilt/shift lens. 45 mm is nice on a FF camera. Very good build.
Cons: I do not like the bokeh, the only con I can think off.
Summary: This lens gets five stars if for no other reason than it has no competitors in the EF mount. However, it is a pricey lens designed for specialist applications and is not for most general purpose photographers. Optics: Shooting wide-open (not really the intended use of this lens), the center is very sharp with the corners falling to good. Tilting or shifting results in even more drop-off in the corners.
