Unveiled: Three New Canon DSLR Lenses and Dedicated Accessories


As part of the biannual Photokina Imaging Fair, Canon has announced several new lenses for their EOS DSLR cameras, in both EF and EF-S mounts. The new models reflect the breadth of possibility within the Canon lens line and are a refreshing sampling of new models and upgrades for a wide range of applications and uses.

An impressive new super telephoto prime lens, the EF 400mm f/4 DO IS II USM Lens enters the field as a replacement for the current EF 400mm f/4 DO IS USM. The multi-layer diffractive optical (DO) technology minimizes aberrations while enabling the unique, compact build of these lenses. The new version incorporates a gapless optical design and dual layer diffractive elements for improved light transmission, reduced flare and overall improved image quality. In addition, large diameter ground aspherical and ultra-low dispersion lens elements have been added to further elevate performance.

As with the current model, Image Stabilization is supported. However this second-generation lens upgrades the IS to provide four stops of shake compensation and, like other high-end Canon telephoto lenses, adds a third IS mode which operates only during exposure. The other two modes are optimized for stationary subjects and moving subjects respectively. The f/4 maximum aperture in combination with the updated stabilization and compact form factor make this a much improved lens in terms of low-light capture; it is an excellent lens for professional telephoto work, including sports and wildlife applications. Needless to say, its size is a boon to anyone who has carried telephoto lenses into the field, and its light, manageable build goes a long way to maintain sharpness. Conveniently, Image Stabilization can stay engaged when the lens is mounted to a tripod, and the minimum focus distance has been shortened to 10.8’.

Physically, the lens is prepared for inclement conditions with a robust build, dust and water sealing, and fluorine coatings on the front and rear lens surfaces. AF stop buttons on the large front ring let you stop autofocus action immediately, and full-time manual focus override allows precise manual control even in AF mode. Also, Power Focus mode enables smooth manual rack-style focusing which is particularly beneficial when shooting video. Its 9-blade circular aperture delivers pleasing out-of-focus backgrounds, and the lens includes a detachable rotating lens collar as well as a dedicated lens hood and hard case.

The new EF 24-105mm f/3.5-5.6 IS STM Lens is a versatile, standard zoom lens designed for full-frame sensors, and is the first of its kind to include a lead screw-type stepping motor (STM), which is a welcome relief for video shooters who will benefit from the motor's quiet and smooth AF action. Additionally, an inner focusing system further supports the STM design to benefit EOS camera's Movie Servo continuous AF mode, while a four-stop Image Stabilization system minimizes shake for sharper photos and video when working handheld. Full-time manual focus also permits precise control of focus; another important factor when shooting video.

Of course, this lens is equally adept at still photography, and its optical design includes two aspherical lenses and an ultra-low dispersion element for controlling aberrations and distortions. The new seven-group design lends to a compact form and, and when combined with Canon lens coating, impressive color balance and minimized ghosting and flare are also afforded. A circular 7-blade diaphragm helps to create smooth out-of-focus highlights.

The last of the new lenses is an EF-S lens designed for Canon APS-C format DSLRs. The EF-S 24mm f/2.8 STM Lens is a prime lens that provides the 35mm focal length equivalence of 38mm for a moderately wide-angle perspective. It is a very compact “pancake” lens, the slimmest and lightest in the EF-S series, yet still features an STM stepping motor for smooth and quiet performance as well as support for the Movie Servo continuous AF function during video recording. When working in One Shot mode, full-time manual focus override is also available.

With a bright f/2.8 maximum aperture, wide angle of view, and low weight, this is a fine lens for low-light capture. Its 38mm equivalent focal length is very adaptable to many shooting situations and ideal for day-to-day photography including landscapes, group shots and street photography. The minimum focus distance is just 6” and one aspheric lens element reduces aberrations for sharp capture from center to edge.  The lens element placement and coatings minimize ghosting and flare and a 7-blade circular aperture also has micro-stepping drive for smoother, quieter transitions.

A pair of new accessories for the above lenses has also been announced. The EW-83M Lens Hood fits the EF 24-105mm f/3.5-5.6 IS STM lens and provides shade for the front lens element to minimize flares. The lens hood is designed specifically to work with the broad range of focal lengths provided by this lens. Of course an added benefit of lens hoods is that they supply a degree of protection for the lens. A lens hood will not only keep unwanted light out of your image but will block light rain from getting on the lens and the absorb impact shock of mild to moderate bumps.

For the new 400mm DO lens a new dedicated hard case has been introduced. The Lens Case 400D features a molded, padded interior shaped to fit the 400mm and is a sturdy hard-plastic carrying case with reinforced siding and folding handles on the top and side. Rubber feet provide it with stability when placed on the ground or a table top and an included shoulder strap enables comfortable carrying options.

what a disapointment that the EF 24-105mm f/3.5-5.6 IS STM Lens isn't F4 thoughout. F3.5-5.6 won't cut it. What was Canon thinking?

Canon already has a 24-105mm F4. The variable aperture brings the price down. Certainly not worth it in my opinion. 

I've been waiting for years for Canon to bring its EF-M 22mm/F2 lens (for the EOS-M cameras) to the EF-S mount - the EF-S 24mm is probably about as close as we'll get.  It'll make a great street lens on an SL1.

Very disappointed in the new lens. What happened to the 100-400mm II??? Rumors stated it was to be released this week. The 100-400 is old and slow --- needs a major upgrade. What gives Canon???  

I want the 100-400 dang rumor???

Is there a package sale for all three?

At this time there isn’t a bundle with all three lenses, no.

canon u 're doin good, keep it up.
