I'm considering upgrading from the Alpha 200 to the Alpha 550. Currently, I take a lot of indoor photos at ISO 800 to avoid using the flash. (Candid photos) The A200 has a lot of noise even though the photos are taken as RAW files. Noise reduction software helps to a point to reduce the noise but at the expense of detail. So it's a balance between the two.

My question is whether or not there is a real improvement in upgrading to the A550 and its sensor. Should the images be cleaner from the A550 sensor using RAW before noise reduction than the A200?

Probably yes. The older lower models like the A200 and A3xx used a CCD sensor which didn't do well at high ISO at all. The modern sensor used in A5xx is CMOS based and like competitors it produces less noise at higher ISO.

The noise reduction software may also be improved since the early CCD models. If you can swing it, currently the A580 with the 16MP sensor gets the best high ISO reviews.
(There is a test on the front page).

Apparently the A550 does apply some noise reduction even in the RAW file, so it's probably not a fair comparison.

thanks for your quick reply

The A550's noise will be significantly lower, of better quality and structure, and less intrusive of details, at all ISOs. From ISO800 and up, the A550 will be a very long measure better.

The biggest differentiator between the two is the type of noise - in the A200, the noise structure is a non-uniform and somewhat clumpy luminance noise, punctuated at higher ISOs by huge blotchy chroma noise that is massively destructive to detail. The A550's noise structure is extremely small-grained, uniform, and virtually all luminance with extremely low chroma and no blotchiness until ISO12800.
