I've been using Canon equipment for eight years and I love their cameras and lenses for their user-friendly, intuitive interface, their robust build and exceptional image quality.
Most participants attending my Digital Photography Courses are Canon or Nikon camera owners, so I'm well-versed in the equipment of both these leading brands.
Other equipment in my arsenal that I highly recommend:
Memory Cards: Sandisk
Filters: Hoya
Tripods: Manfrotto
Light Meters: Sekonic
Radio Triggers: Pocket Wizard
Studio Flash: Elinchrom
Graphics Tablet: Wacom
Monitor Calibration: Datacolor Spyder
Photo Editing and Graphic Design: Adobe Photoshop
