Canon updates its two constant aperture 70-200mm telephotos

70-200mm is one of the most popular short-medium telephoto focal lengths for amateurs, enthusiasts and professionals, and Canon makes two constant-aperture versions for its EOS DSLR cameras. The constant maximum aperture helps low light shooting and creative background blur. The f/2.8 is popular with pros while the f/4.0 versions is more affordable for amateurs.

Both these lenses have been upgraded with new versions.

With this lens, Canon’s aiming to deliver its advanced, premium quality L-series lens quality with a compact, robust and light lens. The new EF 70-200mm f/4L IS II USM weighs 780g, which is impressive for a constant aperture zoom in this class.

It features fluorine coatings to repel dirt and water drops and make cleaning the lens easier, while Canon’s Super Spectra coatings help eliminate ghosting and flare.

Inside, expensive fluorite lens elements are used to correct colour aberrations and deliver high resolution and contrast, while nine aperture blades produce a circular aperture for pleasing bokeh effects in blurred backgrounds.

A new Image Stabilizer unit, based on the one in the Canon EF100-400mm f/4.5-5.6L IS II USM lens delivers the equivalent of a 5-stop shutter speed gain, compared to 3 stops in the previous version of this lens, which also features ring-type USM autofocus and a third-generation EF engine with high-performance control CPU and newly developed firmware for greater autofocus speed and accuracy. It also focuses down to 1m compared to the previous version’s 1.2m.

The Canon EF 70-200mm f/4L IS II USM goes in sale from summer 2018 at a price of £1,299.99/€1,519.99

This upgrade over the existing 70-200mm f/2.8L II is much more modest. The new lens includes moisture and dust resistant seals for challenging conditions, fluorine coated front and rear elements to repel dust and moisture and make cleaning easier, and an 8-bladed circular diaphragm.

The new lens features high-end fluorite and UD (ultra-low dispersion) elements for high contrast and resolution, but the Image Stabilizer is rated at 3.5 stops rather than the 5 stops in the lighter f/4 version (above). The new lens does feature ring-type USM autofocus.

The Canon EF 70-200mm f/2.8L IS III USM will be available from summer 2018 for £2,149.99/€2,499.99.
