Some items can't be shipped from USA based Amazon.com, so this list based in Japan. I believe you need a separate account to order from Amazon.jp, but otherwise all payment methods and such should work as we pay with an USA based card for things all the time. You can change the site language at the bottom of the page. Thanks!
This is the last lens we want for our camera setup. It'd let us get macro (close up shots) of things, but to be honest it may not be something we'd use often in videos. I'd need to play with it to find out, but it would be a fun toy regardless!
