Canon has announced today that three of its highly anticipated new lenses have been delayed until March 2011. The 300mm f2.8 L IS II , the 400mm f2.8 L IS II and the 8-15mm f4 L fisheye zoom.
The lenses have been delayed due to changes in the manufacturing process.
I’m personally most disappointed with the fisheye zoom as I plan to purchase that lens immediately and arriving in March it will miss most of my winter work where it would have been very useful.
