http://pixinfo.com/en/articles/canon_powershot_g_evolution/ Um artigo bastante interessante que relata testes comparativos entre todas as Canon Powershot da linha G, desde a G1 até à G10. Algumas conclusões a retirar dos testes: - Our tests show a great improvement in colors and tones over the years. - During this test we (...) rank the images according to the fine details (...). The best were the images of the G7, G9 and G10 at low sensitivity, while the worst images came from the G1, G2 and G3. - At A3 sized prints despite the common belief newer, higher resolution cameras are better performers, when it comes to image noise. - After analyzing the 10×15 cm prints, we can say that the overall image quality does not depend on the resolution, and that a good noise filter can make the difference.
