Question about sensor or lens resolving - DCS-420

Post by precertvideo »

Right, please bear with me while I try to phrase this right...

Using my DCS-420 (though it happens with my EOS-DCS-5, as it's the same sensor, etc.) often areas in sharp focus, (especially thin things such as hairs,) can 'pixelate'/show up the line structure, whereas areas out of focus can appear completely non-digital & film-like.

The image below shows what I mean

This was taken with a 'decent' lens, a Tamron 90mm macro. File processing doesn't seem to add/detract anything.

I suppose this pixelation happens only with better lenses-is this a case of the lens resolving more detail than the senosr can record?

You're seeing color aliasing and moiré, common in the early DSLR's. Modern cameras will actually blur your shots (using an anti-aliasing, or low-pass, filter over the sensor).

See here for some more examples and info (shot with a Kodak NC2000):

In other words, it's not a lens issue.
