The Rokinon 24mm f/3.5 Tilt Shift Len for Canon is a wide-angle, full-frame lens fitted with the perspective control and tilt-shift functions. A tilt-shift lens allows the user to control perspective and correct convergence of lines within your frame, useful especially in architecture, landscape and product photography. The optical tilt mechanisms enable precise control of depth of field along with perspective control. It is compatible with both digital and film formats with an angle of view of 83.5deg. and on an APS-C size sensor has an angle of view of 56.9deg. and focal length equivalent of 38.4mm.
The tilt-shift function on the 24mm f/3.5 lens allows adjustment of the focal plane by an angle of +/-8.5deg. and enables parallel shift of the optical axis by +/-12mm. The tilt-shift section of the lens rotates left 90deg. (click-stop adjustment each 30deg.) and the lens mount can rotate left or right by 90deg. (click-stop adjustment each 30deg.).
The lens is comprised of 16 elements in 11 groups, including two aspherical lenses and two Enhanced Dispersion (ED) lenses, which reduce aberrations and provide sharp details and accurate color separation. Multi-layered, anti-reflective UMC coating on each lens element allow even light transmission, minimizing flares and ghosting.

I use this lens primarily for real estate and product photography. The Rokinon is less than half the price of its Canon equivalent, and nearly it's equal in image quality and function. Real Estate: If you are serious about getting into any type of structural photography, this is the lens to start with. I curently have little need for the tilt function, but the ability to shift is key for producing proper vertical lines. This lens performs very well at higher apertures, which is where you want to be anyhow. At f/11 and below, you can see it becomes a little softer than the Canon, but for the price, and the fact that I hardly use it below f/16, it's a no brainer. Product Photography: I primarily use this lens to shoot garments for catalog photos, where the garment is parallel to the sensor plane to maintain proportion. The main reason I first chose this lens for the purpose is because it is a nice sharp prime, and I do not have to worry about the lens sagging and having to refocus if I have to take some time to adjust my lighting or subjects. The reason I continue to do so is the fact that it is sharp enough to practically count the threads in fine cotton apparel. The ceveat is that if there is so much as an eyelash on the piece, it will show up. The shift function is a bonus in this application, where if you can't position the camera directly on the subject, you don't have to take your camera out of parallel to center it, which would cause distortion. This lens has its specialized applications, and is not for everyone. If you are doing any kind of structural work, or for certain types of products, this is a sure winner. All T/S lenses that I know of are manual focus, but in my opinion, that kind of forces you to be more mindful of your subject. One downfall (which is truly nit-picking) is the lack of communication with the camera, which is present in the Canon. In your EXIF data, it appears as a 50mm lens, and does not retain your f/stop information. This is helpful to me for analyzing and repeating results. Simply taking notes solves that. One last thing is the mechanism itself. Some have complained (elsewhere) of the knobs being too small - which I tend to agree to an extent. I have large hands, and the knobs could use to be a bit bigger, but too much larger, and there would be less room for my finger to get a firm hold. Lastly, the tilt and shift rails have very little tension, so you also have to hold your adjustment against gravity until you lock your position - which I did not have to do with the Canon. All-in-all, for my purposes I believe this lens to be 95% the lens that the Canon is, but for the same money, you could buy two of these and still take your family to dinner twice a week - for a month. The only reason I give it 4 stars is because 4.5 is not available, and the cons listed above keep it from being a 5.
