Not sure this really means anything to be honest. Since compact cameras have become widespread, and even more since the smartphone era, I believe that many "portable" cameras/lenses have been branded as Zeiss and as far as I know it did not necessarily mean that they benefited the quality level and control the brand built its fame on, let alone be manufactured by Zeiss themselves. I always thought these were just labels, like "Endorsed by Zeiss themselves, buy it!" rather than any real I guarantee, but it's still better than nothing as Zeiss wouldn't risk its reputation by putting their name on the worst cameras I suppose.

Please correct me if I'm wrong because I'm not sure at all (Chen, maybe you have experience with this?). Sorry for the misinformation if I am.
