Sorry to be pedantic Nick , but (as yet untested as) being on par with an uncooled chip doesn't yet make CMOS 'much superior' to CCD. CMOS has certain advantages in the way that it reads information.In theory this makes for bigger sensors at a reasonable price , but as far as I know CMOS has not yet exceded CCD quality in its present form . Hence Kodaks seperation in quality terms in two of its own products. And I must admit to being stumped on :- >Another big advantage (for me) of CMOS is the lack of a dust problem on >the sensor which can become a real pain. The only way that I know to get rid of dust is to clean it off the sensor , a task that is far easier with a removable back. Having looked closely at the test files from the new Canon, dust is obviously still a problem on their CMOS.Be very interested to hear how other CMOS sensors overcomer this problem.
