Canon officially announces the EF 70-200mm f/4L IS II USM  and EF 70-200mm f/2.8L IS III USM telephoto zoom lens.

EF 70-200mm f/4L IS II USM

The new version of its popular 70-200mm F4L telezoom features numerous improvements over its predecessor, including five stops of stabilization. The updated IS is now quieter, and now features three modes, designed specifically for shooting still and moving subjects. Weighing 780g, the new 70-200mm F4L is 40g heavier than its predecessor.

The EF 70-200mm f/4L IS II USM uses a combination of a Ring USM and a new third generation EF engine, which features a new high-performance control CPU and newly developed firmware. The silent functioning autofocus can also be tweaked manually and allows a close focusing distance of 1m, compared to the 1.2m on its predecessor.

The Canon EF 70-200mm F/4L IS II USM will be available later this month for $1299 – Amazon| B&H Photo Video | Adorama.

Canon EF 70-200mm f/4L IS II USM Lens Officially Announced

Key Features:
  • Constant f/4 max aperture
  • Ring-type USM focusing
  • 5-stop Image Stabiliser
  • Weighs 780g

The Canon EF 70-200mm f/4L IS II USM weights 780g and the Fluorine Coating reduces the amount of dirt and water drops clinging to the lens, while theSuper Spectra coatings eliminate ghosting and flare. The EF 70-200mm f/4L IS II USM’s fluorite lens elements are capable of correcting colour aberrations while the f/4 constant aperture provides consistent exposure in a range of varying lighting scenarios.

The nine blades on the EF 70-200mm f/4L IS II USM ‘s circular aperture create a pleasing bokeh effect, blurring the background and helping to accentuate the subject. The EF 70-200mm f/4L IS II USM also features a new Image Stabiliser unit, based on the design of Canon’s EF 100-400mm f/4.5-5.6L IS II USM, which delivers the equivalent effect of a shutter five-stops faster, compared to the previous lens’ three-stops.

The new Canon EF 70-200mm f/2.8L IS III USM is an ideal lens for professional photographers who shoot with the Canon 1D and 5D series of DSLR cameras. The inclusion of Air Sphere Coating (ASC) technology helps to reduce flaring and ghosting, and suppresses the reflection of light.

The EF 70-200mm f/2.8L IS III USM also comprises fluorine-coated front and rear elements. Other coatings are reportedly ‘improved’.

The Canon EF 70-200mm F2.8L IS III USM will be available in August for $2,099 – Amazon | B&H Photo Video | Adorama. 

Canon EF 70-200mm f/2.8L IS III USM lens officially announced

Key Features:
  • Optical Image Stabilizer up to 3.5 shutter speed stops of correction
  • Fluorine coating on front and rear elements helps to reduce smears and fingerprints
  • Inner focusing system with Ring Ultrasonic Motor
  • One fluorite lens and five UD lenses helps to provide high-image quality
  • Minimum focusing distance of 1.2m (3.9ft)
  • Lens features 23 elements in 19 groups
  • Circular eight blade aperture

Thanks to its fluorite and UD optics, the EF 70-200mm f/2.8L IS III USM delivers high contrast and excellent resolution. Shooting in low light is also no problem for the EF 70-200mm f/2.8L IS III USM, thanks to its fast f/2.8 maximum aperture, which is constant throughout the zoom range and lets in twice as much light as an f/4 lens.

Camera shake isn’t something users of the EF 70-200mm f/2.8L IS III USM should be concerned about either as a 3.5-stop Image Stabiliser compensates any blur caused by movement. A ring-type USM motor offers silent autofocus and manual adjustments can be made at any time with a simple twist of the focus ring.
