2013 May

  • Just in case you'd forgoten, the lens was first announced in February 2011, with a 'late 2011' availability...
  • 13th There is a Canon event on the 31st, which has been mentioned for the release of the 200-400, but so was tomorrow... [CR]


  • 27th A potential date for announcement - May 14th [CR] Availability in the Autumn - could this tie in with the info we had last week?
  • 19th We're told (thanks) that the formal announcement of avallability for the 200-400 will run alongside a camera announcement, most likely the 7D mk2, in time for shipping of a few units in the Autumn. There are quite a lot of test units in circulation and despite there being no official price, a lot of lenses have been pre-ordered. If (and at £10k that's still a big if) the preorders are taken up, supplies will be very thin on the ground until well into 2014.


  • 4th A video of the 200-400 being used is at LL


  • 10th 'Soon' is redefined as production of the 200-400 starting in Q2/13 [CR] and at well over $10,000
  • 3rd Canon Singapore is saying that the 200-400 will be available soon [CS-fb]

2012 December

  • 3rd The lens is possibly expected within months... [CR]


  • 15th After mention of the delays, I've heard [thanks] from a couple of people who used the lens at the Olympics and Wimbledon, unfortunately they just said how well it worked, and how they really wanted to add one to their day to day equipment. Whatever the issues might be, they didn't notice (note that this is on a sample size of two, both with only relatively short use of the lens).
    • Has anyone trying the 200-400 noticed any potential issues, maybe with the extender?
    • The image below is from Bob Atkins' look at the 200-400 and shows the bulge for the extender
    • Could the issues be related to the ergonomics of all those controls and the bump?
  • controls for ef200-400
  • 14th Still no sign of an announcement...
  • Where is that 200-400 lens - suggestions [CR] that unforseen design/manufacturing issues have hit the product.


  • 8th Looking for the 200-400? Even though not formally announced, it looks as if it's going to go for around 10,200 euros.
  • How so?
  • If you look at some sites, you'll find various bundle deals [FK] 1DX + 500/4 is 16498 whilst 1D X + 200-400 comes to 16668


  • 22nd We're told [thanks] that the EF200-400 will finally be properly 'announced' for the PhotoPlus show in New York (Oct 24-27) and become available later this year.


  • 31st Interesting positive report about using a 200-400 [PB]
  • 17th If you're a CPS member covering the Olympics, then I'm told that there are several loan lenses available to try out...
  • 3rd Seen at Wimbledon - launch 'soon' - Thanks for the pic! - Full res pic on Google+

  • 29th More suggestions of an 'announcement' [CR] BTW, the lens was first mentioned on the 7th Feb, 2011


  • 23rd With expectations of a 5D mk3 announcement on the 28th, there is also a price $11,000 and imminent release date for the 200-400 [CR]

200-40 sighted in KenyaJanuary

  • 23rd Just when I'm thinking there's still no sign of this lens getting a release date... and then it's seen in Kenya being tested with a new body that might be the 5D3 [AA] Launch in March/April.
  • Lots more photos at AA

2011 November

  • 4th The 1D X and C300 (with lenses) have all been announced. Not even an official announcement yet for the 200-400.


  • 27th The EF200-400 is not on the list of lens due dates, and we've been told that there is no more info about it until after it is formally announced - probably at the same time as other product announcements.


21st We're told that the £10k price listed at Park Cameras was an error - no price has as yet been given out by Canon.

19th A page appears at a UK dealer with a £10k price tag.

We'll see if we can get any more detailed info as to whether they think this is for real, or just a 'placeholder' value.

A new long zoom

Canon is developing the EF 200-400mm f/4L IS USM Extender 1.4x lens, which features a built-in switchable 1.4x teleconverter.

With the converter in place, it becomes a 280-560mm F5.6 lens. It's designed for sports and wildlife photographers and the lens will feature weatherproof construction.

It is scheduled for launch later this year. It's not known if it will make an appearance at this year's Focus On Imaging trade show in Birmingham (UK).

Price - unknown, but not cheap!

Awaited with interest :-)
