Old Canon IXUS 700 colour close-up.
Even though this 11 year old Camera sees only 7.1Mpix (3072 X 2304 pixels), at 300dpi (which is Offset Print resolution), it gives a 26cm x 19.5cm printed image size. This amounts to an A4 size image at 300dpi, which is good enough for glossy A4 publications, let alone the 72/90/144dpi for the Internet.
