I like Photo Plus from Future Publishing in the UK it is a Canon specific magazine, Canon cameras and accessories, They do test 3rd party lens, grips, flashes, printers but it is compared to the Canon branded gear. They have a face book presence where you can ask questions if you are having issues with your gear. Lots of good info contained in the mag but it is more $$$ than say Popular Photography and other US based photo mags. I subscribe to several of the UK mags like Photo Plus,Digital Camera,Digital Photography. I am an analog material fan. Barnes and Noble book stores can feed your camera info lust and drain your bank account at the same time.
