When it comes to noise, it's all in the trade-offs. Both the Panasonic and the Canon PowerShot A710 IS have noise in their ISO 100 shots. Canon more aggressively suppresses it, yielding a softer image, but not so soft that you can't read the text or the tape measure. Panasonic, on the other hand, maintains sharpness, but the color noise interferes with the readability of the text and tape.
