When you think of allergies, several things come to mind, like peanuts, pets, and pollen. But photography? Strange as it may sound, your choice of digital camera could cause an allergic reaction. Canon has issued a product advisory that warns the rubber grips of some EOS Rebel T4i Digital SLR (EOS 650D/EOS Kiss X6i overseas models) cameras contain a substance that could cause people with sensitive skin to develop a rash or have some other allergic reaction.

Canon's new EOS 60Da DSLR camera is the long-awaited successor to the EOS 20Da and just the thing for photographers who prefer to stare at space than at flowers and other earthly objects. According to Canon, the freshly minted 60Da is optimized for astrophotograhy and is ideally suited for astronomers and hobbyists who want to snap photos of the night sky.

It takes a serious commitment to photography to drop $6,800 on a DSLR camera body with no lens, and if ever you might be tempted, Canon's EOS-1D X is it. Canon calls it a "high-speed multimedia juggernaut replacing both the EOS-1Ds Mark III an IOS-1D Mark IV models." We call it a smarty pants camera fully loaded with funtastic features, and a new body to boot.

If you find yourself at Sea World, be sure to check out the Pets Rule show. You'll see a variety of animals perform some amazing tricks, like a cat walking a tightrope. There are ducks, dogs, and even a pig all prancing around acting like humans. But one thing we've never seen before is a mouse that can do math. Canon's latest rodent -- X Mark I Mouse Lite -- can do that, as well as perform a few other tricks.
