I know that CMOS is much more noise free etc.... But is this real,or only good noise reduction from Canon?

This picture is taken with Canon 300D 18-55 (55mm) and with Nikon D70
with Sigma 18-50 (50mm)
I noticed that 300D is loosing details in texture of the building..
Left is Canon ,right is Nikon

from what i have read elsewhere, the CMOS appears to be more noise free but this is because (at least partly) Canon use more noise reduction in camera, even with RAW images.

If you are comparing the D70 and the Rebel, i doubt that the noise on either of them is enough to be a concern on prints and will be no more than using a fast ISO film.

CCD is an expensive technology which gives good results. CMOS is like the two extremes, most very cheap digicams and web cams use cheap CMOS which can be produced for a fraction of the cost of a CCD (at a fraction of the quality however unfortunately) at the other end a high quality CMOS such as what Canon uses in its DSLRs offers equal quality and powersaving advantages over CCD. There you go, it is as clear as mud!

Basically, if it is cheap and says CMOS forget it.

CMOS chip sensors have always been way too insensitive to light to produce high res, high quality images. These chips have been evolved to produce an economical solution for the high-res dSLR's. They are now, for the most part, equal to CCD's, with the bonus of a lower power consumption. Don't get caught up in comparing different photo's from different cam's based on the image sensor, much of the obvious differences are a result of the image processing the camera's hardware does.

CMOS, cheap & poor quality!

CCD, expensive but has great quality!!!

Obviously ignore that, CMOS sensors are being used in top of the line cams because they are the best solution for those applications.

Unless i am mistaken, CCDs are produced using a specialty process, whereas CMOS sensors can be produced on the same equipment as ram and microprocessors. This is where the price savings come in. Most people don't worry too much about sensor type usually just image quality and power consumption.
