Now let's subject the little Canon to some Siemens-stars. Shot with Canon IXUS 780IS at 11mm (=60mm on film), f/4.0, 1/25 sec, ISO 200 on auto-focus.
Shown here is a 100% crop from the center (left) and a 100% crop from a corner (right).
The center-crop is very sharp (easily as sharp as the best lenses on a Nikon D300) and has good contrast, while the corner crop turns out a clearly softer both in sharpness and contrast.
See for comparison here
Looking at the equivalent shots from the D300 you can see that the Canon displays some sharpening artefacts in the centre of the Siemens-star. You can also see some CAs in the corner shot.
As I don't have a standard kit-lens from Nikon I cannot fairly compare both but let me say as much: The Canon zoom holds up quite well and may not be behind a standard kit lens from Nikon at all. But the benefit of the D300 (or any DSLR) is that you can buy better lenses if you
- need more image quality
- more wide-angle or more tele-reach
- better low-light capabilities
I won't award any points here, because the Canon holds up quite well given the principal limitations of a p&s.
