Canon EF 200-400mm f/4L IS USM lens is a new lens to be released soon. This lens now in use at London 2012 Olympics games by Olympic photographer Jeff Cable. Hopefully, this is a good sign for the availability of this lens and Canon will begin shipping it out to the mass market sooner rather than later.
About the price:
The price tag about this lens is at $11,000 to $12,000 as rumored.
The development of this lens was announced alongside the official unveiling of the new EF 500mm F/4L IS II USM and EF 600mm F/4L IS II USM lenses – both of which are now starting to trickle into commercial availability.
