Prized for event, portraiture, and sports shooting, the Canon EF-mount Sigma 70-200mm f/2.8 DG OS HSM Sports Lens is a flexible telephoto zoom characterized by its bright and sophisticated design. The fast constant f/2.8 maximum aperture excels in difficult lighting conditions and also offers increased control over depth of field for isolating subjects. In regard to the optical layout, an impressive 10 low dispersion elements are used to greatly reduce chromatic aberrations and color fringing for improved clarity and color accuracy. A Super Multi-Layer Coating is also featured and helps to suppress ghosting and flare when working in strong lighting conditions.

Complementing the optics is an Intelligent OS system, which minimizes the appearance of camera shake for sharper results when shooting handheld. A Hyper Sonic Motor is also used to provide quick and quiet autofocus performance along with full-time manual focus override. The physical design of the lens also incorporates several seals to guard against dust and moisture, and a water- and oil-repellent coating has been applied to the exposed elements to prevent moisture, fingerprints, or smudges from sticking to the surface.

One Special Low Dispersion (SLD) element and nine F Low Dispersion (FLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy, as well as spherical aberrations for reduced distortion and improved sharpness throughout the zoom range.
A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
Front and rear lens elements have been treated with a water- and oil-repellent coating to benefit working in harsh environmental conditions.

So, I was very skeptical of this lens and adapter and whether or not it would work correctly on my Canon RP. I previously had an older Sigma lens and tried to use the adapter with it but, it didn't work. The vignetting was horrible and I would have to manually turn on cropping in the camera settings. That is not the case with this lens and adapter. There's no vignetting and I'm still shooting full frame and not cropped. If you're looking for something that works as well as the Canon version for a fraction of the price, then this is the lens for you!
