Another camera you've never actually used, so you have to resort to scouring the Internet for something negative you can exaggerate. >Every other review of this product line, including >the newer FZ35, prominently notes the noise issue. TrustedReviews: Image Quality 10/10 * At the minimum ISO setting the image quality is very good, with no trace of noise. * At 200 ISO there is virtually no difference. * Noise is starting to appear at 400 ISO, but there's still plenty of fine detail and the colour rendition is still accurate. Digital Camera Review: ...it's clear that Panasonic has made some serious strides in making its high-sensitivity settings more usable. Although noise reduction can be fine-tuned, I found the FZ28's default approach to hit that elusive balance between noise and noise reduction about as well as could be expected. ISO 800 is clean enough this time around to be almost "no reservations" usable, and colors hold their vibrancy throughout the range. Steve's Digicams: Imager noise was well controlled when using the higher ISO capabilities of this camera. I found you can create nice large prints using settings of ISO 800 and below. ...great image quality... I guess these and other favorable reviews just don't exist in your parallel universe. ;) -- Best regards, John "Never argue with an idiot.

You have to be making assumptions because you have NO direct experience with my model camera, and because you're projecting your own limitations onto me, which likewise isn't valid. -- Best regards, John "Assumption is the mother of all screw ups."
