Focus-on-Imaging is the must-attend event for photographers looking to try out the latest kit and benefit from special offers. This year, Nikon, Panasonic, Pentax, Sony and others will be on hand. And, up until last week, Canon also planned to attend the four-day trade show. But, as we learned on Monday, Canon has been "reviewing its marketing strategy for the year" and has decided to pull out of the show - just two weeks before it was expected to start.

Now, that's a blow for Focus-on-Imaging, especially since one of its ads showed "Suzy The Chimping Ape" pose with a Canon digital SLR.

In an email to BJP, Focus' organisers say that "this years’ Focus ad campaign, and last years’ actually, featured photographers – all of whom were shot using their own kit. We cannot seek manufacturer’s approval before featuring photographers using their own equipment. We’d never meet any of our deadlines."
