I’m using a Canon Digital Rebel XT (350D). It is small and light, ideal for travel, and has been great for many years. I’ll probably upgrade to a 7D (or maybe even 6D) in the short term, when funds allow – I fell in love with the 7D’s viewfinder.
Yes, I think of it as if the joystick was stuck to the back of the head of the protagonist (Y-axis only), so I have to invert it. Doesn’t feel right otherwise.
