All the cameras I've had have the NTSC or PAL selection in the menu.
However a big downside of buying out of country is no warranty. Or you may discover you have to ship it to the country you bought it in.
I plan to purchase Canon Powershot S3 IS from Japan. I need to know if it will work in India, particularly the video format. Can I view the pictures/movies in PAL tv?Is there a separate model for PAL?
