Canon News: Pair of wide-angle lenses announced

In what has been billed by Canon as the 'year of the lens' (we're still waiting, but perhaps another reason to look forward to the World Cup!), Canon have announced two new wide angle lenses into their extensive line-up of EF lenses for EOS DLSRs.

Canon EF 16-35mm f/4L IS USM

Canon EF 16-35mm f/4L IS USM

  • High performance L-series ultra-wide zoom lens in a compact design and Optical Image Stabilizer for up to four stops of correction*.
  • Three aspheric lens elements, including a large-diameter aspheric lens, help correct aberration.
  • Two UD lens elements help reduce chromatic aberration from the center to the periphery throughout the entire zoom range for excellent image quality with high resolution and contrast.
  • Optimized lens coatings help provide excellent color balance while also helping to minimize ghosting.
  • Highly resistant to dust and water intrusion, enabling shooting even in harsh conditions**.
  • Inner focusing and ring USM for silent, fast and accurate autofocusing.
  • Circular aperture (9 blades) delivers beautiful, soft backgrounds.
  • Minimum focusing distance of 0.92 ft/0.28m across entire zoom range.
  • Full-time manual focus allows manual focus adjustment while in AF Mode.

    * Based on CIPS (Camera & Imaging Products Association) standards. Testing performed using EOS-1D X Digital SLR camera at focal length of 35mm (35mm equivalent).
    ** Requires a Canon PROTECT filter (sold separately) to be mounted.

I'm lucky enough to have the f/2.8 version of this lens (which doesn't have image stabilisation), and found it a really useful focal range - 35mm is useful as a walkaround lens, and 16mm really does give an impressively wide persepctive (on a full-frame body, at least).

Canon EF-S 10-18mm f/4.5-5.6 IS STM

Designed only for cameras with the APS-C sensor (cropped), this lens creates an incredibly wide perspective.

  • EF-S ultra wide zoom lens with an impressive starting focal length (16mm in 35mm equivalence).
  • Compact design made possible by a new 4 group zoom optical system.
  • A stepping motor (STM) and newly-designed focus mechanism support the Canon EOS Movie Servo AF function to provide smooth and quiet continuous AF during video recording, as well as when shooting photos.
  • A large diameter element and an aspherical lens element help correct aberration to achieve higher image quality
  • One UD lens element helps reduce chromatic aberration throughout the zoom range for excellent image quality with high resolution and contrast.
  • Optical Image Stabilizer for up to four stops of correction*.
  • Enhanced lens coatings help ensure outstanding color balance while minimizing ghosting and flare.
  • Circular aperture (7 blades) creates beautiful, soft backgrounds.
  • Rear focusing system, high-speed CPU and improved AF algorithm allow high speed autofocus.
  • Full-time manual focus allows manual focus adjustment while in AF Mode.

    *Based on CIPA (Camera & Imaging Products Association) standards. Testing performed using the EOS 7D Digital SLR camera at a focal length of 18mm (29mm in 35mm equivalence).

Nikon News: AF-S NIKKOR 70-200mm f/4G ED VR lens announced

Nikon have announced a new 70-200mm lens, the  AF-S NIKKOR 70-200mm f/4G ED VR.


  • FX-format telephoto zoom lens with 70–200mm focal range (105–300mm when used with a Nikon DX-format SLR).
  • Constant f/4 aperture throughout the zoom range.
  • Vibration Reduction (VR) system: minimizes camera shake and lets you shoot at shutter speeds up to five stops slower.
  • Nano Crystal Coat greatly reduces ghosting and flare.
  • SWM (Silent Wave Motor) enables quiet and accurate autofocus.
  • Two focus modes: A/M (autofocus with manual override, AF priority) and M (manual focus).
  • Minimum focus distance: 1 m.
  • Lightweight body for a telephoto zoom lens.
  • RT-1 tripod collar ring (optional accessory): enables the lens to be rotated freely for smooth transition between vertical and horizontal orientation.

Canon News: Updated 'Big Dogs' announced

After a bit of a pause, Canon have now offically announced the upgrades to two of its flagship L lenses - the new 500mm f/4 L IS II and 600mm f/4 L IS II.

  


They're not exactly cheap at £8999 and £11299 respectively, but come with some new features to tempt you:
  • They're much lighter (but still 3.2kg and 3.9kg respectively)
  • Redesigned internal optics
  • Improved image stabilisation
  • water-repellant Fluorine coatings on front and back lenses
 More details are here (500mm) and here (600mm)

Canon News: 200-400 f/4 L IS USM Extender 1.4x on its way

As part of a clutch of new announcements from Canon, the one that's caught my eye is that Canon are developing a new lens - a 200-400mm f/4 L IS USM lens... with an incorporated 1.4x extender (extending the range to 280-560mm - on a non-cropped body).

It's due out in 2011 and has the potential to offer a great compromise of useful telephoto focal length, relatively low aperture and hopefully weight.  Lions in the Masai Mara will have to get used to perfecting their smiles looking into this I think...

Pricing is hard to guess, but Nikon's 200-400 f/4 in the UK is around £5k, so it's certainly going to a painful upgrade for those looking to move from their 100-400 lens.

  • 4 Extra-low Dispersion (ED) Elements
    Offers superior sharpness and color correction by effectively minimizing chromatic aberration, even at the widest aperture settings.

  • Three Focus Modes
    A/M mode joins the familiar M/A and M modes, enhancing AF control versatility with fast, secure switching between auto and manual focus to accommodate personal shooting techniques.
