Canon has launched three new EF lenses that will please wide-angle users and working professional photographers.
EF 24-70mm f/2.8L II USM
The standard lens for many professionals has long been the EF 24-70mm f/2.8L USM, this new model takes from the old and starts the 25th year of EOS with completely redesigned optics to provide outstanding clarity, image quality and added durability. One of the specific improvements is the performance at the 70mm setting where greater detail and less distortion are key characteristics.
Using it’s in-house optical technologies the new lens features two Ultra-low Dispersion (UD) and one Super UD aspheric elements to minimise chromatic aberration and colour blurring. In addition to the Super Spectra coating on each element the front and rear elements have been given the additional Fluorine coating that makes it much easier to remove dirt and fingerprints.
A ring UltraSonic Motor (USM) is used to drive the AF and it works in conjunction with a high performance CPU to deliver accurate, silent and responsive AF. Close focus is 0.38m the same as the old version. A new 9-blade aperture assembly should improve the bokeh over the old model’s 8-blade unit.
As an L-series lens the EF 24-70mm f/2.8L II USM has been created to survive the harsher professional use with revised and strenghtened construction giving better resistance to shake and shock – the achilles heel of the old lens. Of course the lens offer the standard dust and weather sealing, yet all this has been acheived whilst making the lens some 10mm shorter in length.
EF 24mm f/2.8 IS USM & EF 28mm f/2.8 IS USM
Canon claims these are the worlds first wide-angle prime lenses to feature optical Image Stabilizer (IS). Aimed at landscape and reportage photography the four stop stabiliser will allow handholding at shutter speeds that are simple ridiculous. The IS system detects panning movement and will switch the IS system in to mode-2 IS automatically. These two lenses both focus closer than the old non-IS versions at 0.2m (24mm lens) and 0.23m (28mm lens) and optical quality is a step up too with an aspherical glass moulded (GMo) lens element correcting aberration throughout the optical system. To improve the bokeh both lenses use a 7-blade aperture unit which yields soft background blur.
I can’t help but think that the new lenses with IS and improved optical performance are going to be expensive, maybe signifiicantly more than the models they replace, just have to wait and see a little.
