I'm purchasing a lovely DSLR this weekend, and was wondering if the prices of camera accessories would be cheaper in Japan than here? ('here' for me is Australia). Specifically I'm after some memory cards (compact flash, 2-4gig ideally), a spare battery (for Canon 400D, not sure how specific they get) and if I can afford it a macro lens (Canon). I'll be looking around Osaka and Tokyo and have heard they both have pretty good camera/electronics stores - do they turn out cheaper?
