ok lah, his definition of serious is different from yours.
Some people do need to print BIG. the drawback (in terms of image quality) of the s3pro/s5pro is really their resolution. Fujifilm decides to sacrifice precious sensor space for those pixels to capture highlights. U gain some, u lose some.
But I have printed out A3+ size prints from my s3pro and they look quite sharp/detailed even when I view it from like 5 cm away.
