With both tilt and shift movements, as a wider version of the earlier TS 35mm f/2.8 SSC FD, the original Canon TS-E 24mm f/3.5 caused quite a stir when introduced in the early 90's.

The main reason to bought this product was the capability for perspective correction when shooting architecture, I do a lot of this kind of photography. This feature is nice and works very well. Saves me a lot of time in photoshop. Barrel distortion is fine too.

This lens is well built and it produces great sharp images. it works great for architectural applications but It doesn't have auto focus; it can be used for selected applications in fast pace environments like weddings.

Durable; Nice Bokeh; Strong Construction

Heavy; Slow Focus

This lens is great if you have a more advanced knowledge in photography. It gives precise colors and exceptional picture quality.This lens is a little pricey but worth it. This lens also gives the photographer the advantage to tilt the lens which is a huge advantage.

Pros: Cons: Heavy Other thoughts: The best usage: a landscape with horizontal tilting for the better DOF. The agngle of the tilt is very small for the real architechture works. Miniatures - toys for no more than 10 pictures, after that you realize that it is not series.

PMA 2009 was a show distinctly light on noteworthy announcements, but one of the most technically interesting developments may well have slipped under the radar of many enthusiast photographers.

Excellent central sharpness even at F3.5; Minimal chromatic aberration; Almost no visible distortion; Extensive and highly flexible perspective control movements; Exceptional build quality

Soft corners when shifted (need to stop down to F11 - F16 to achieve best sharpness; Expensive

Canon's latest wide-angle tilt-shift optic promises a higher quality over the entire imaging area and a wider range of lens movements over its predecessor.

Excellent optical performance; Very good build quality; Good control over tilt-shift movements; Electronic coupling with Canon EOS cameras

Expensive

The reason most people give for not investing in this top tier glass is that perspective correction in software is a cheaper and an efficient option. While it is possible to straighten lines and scew/distort images in software to get a desired result, most people are missing the main point of these...

Now it's not overly surprising that the lens is capable of providing a very high quality based on a neutral shift setting. But what about the extremes then ? There is, of course, a decrease in image quality when shifting the image frame towards the edges of the image circle.

This lens has exceeded every expectation I had. Total game changer. I shoot architectural and real estate and I wish I added this lens to my collection a long tine ago.
