The A530 offers an ISO 800 setting that seems to be a new trend in digicam design. Sony has bumped the ISO ceiling up to 1000 in this year's Cyber-shots, obliterating the old 400 limit. This can be something of a mixed bag, as many have pointed out. The price of higher sensitivity is more noise. In fact, with more megapixels crammed onto the tiny sensor surface, even ISO 400 exhibits more noise than it did in the good old days when a 3-Mp sensor was hot stuff.
