I’m working away on the A900 review, this time I have some ISO shots for you, and comparisons to the A700. Check it out here. The crops below are ISO 6400, and you can see the A900 (left) leaves more details intact. I guess Sony is using less luminance reduction with this camera. I also made sure the scale was right for the comparisons, so the A900 isn’t benefiting from the extra 12mp.
This weekend I hope to post some down-sampled ISO comparisons using 24mp and 13mp image sizes, and RAW shots reworked with noise reduction software.
