The EF17-40mm f/4L USM is an ultra wide angle Canon EF zoom lens meant for professional and high amateur SLR EOS camera users. While it is an excellent lens when used with an analog SLR camera, the EF17-40mm f/4L USM is especially well suited for digital SLR cameras with an imaging sensor size smaller than the 35mm format.

Fujinon A17x9BRM

With the new A20x 8.6 (for 2/3-inch format cameras) and S 20 x 6.4 (for 1/2-inch format cameras), Fujinon continues its successful line of highquality lenses in the professional range, which started with the introduction of the A19 x 8.7 and S19 x 6.5 lenses to professional users.

As its predecessors, the new A20x /S20 x lenses combine superb optical quality with rugged construction to withstand even the hardest daily use, features previously found only in the range of broadcast lenses.

Canon introduced the 24-70mm f2.8 L to it’s professional series of lenses as a direct replacement of the 28-70mm L lens that dominated this part of the professional mid range zoom market for well over 10 years.  Improvements were made all round and included a faster auto focus, better image quality and improve weather proofing.

The Canon EF 1.4x II Extender is a high-quality teleconverter that preserves the image quality of the lens it's mounted to and multiplies its focal length by 1.4x. When combined with pro level EOS cameras & EF supertelephoto lenses with image stabilization, near imperviousness to weather extremes is achieved thanks to rubber gasket seals. Improved anti-reflective internal coatings also increase transmissivity & performance in backlit conditions.
