Canon EF 16-35 f/2.8 L II USM Professional Ultra Wide Zoom Lens.
The lens has the most powerful zoom among Canon wide-angle lenses, and also provides exceptional sharpness of the edges of the image. A fixed f/2.8 aperture ensures high quality shooting in low light conditions, as well as full depth control over the entire zoom range. The model has a very effective range of focal lengths and allows you to smoothly go from extreme values with an extreme perspective to a more familiar angle of view.
The lens has all the advantages of Canon's L-series optics and guarantees an excellent result of shooting in any genre that traditionally requires the use of wide-angle optics: architectural photography, interior shooting, landscape.
The lens is equipped with an ultrasonic drive that provides smooth and quiet autofocusing. The front part of the frame at work remains stationary, which simplifies the use of spectacular light filters and nozzles, circular polarizers, etc. The photographer has the ability to manually correct the sharpness induced in the automatic mode without having to exit the autofocus mode. Like all lenses of the L series, the model is designed for shooting in all weather conditions and is protected from dust and moisture.
