does a200 have any firmware? People in Dyxxum said there's no firmware for it.
and i wondered why the a100 had the MLU but the a200 doesnt D:
All digital cameras have firmwares. Firmwares are programs 'hardcoded' for specific electronics. As you are referring to a200, there is no update to the factory firmware.
My only explanation is that when a100 was released, it was the only camera Sony had, thus has additional features such as MLU then. Now, this feature can only be found in a700 which comes out about the same time as a200,a300,a350. These cameras varies in features and of course price. It is probably a Sony marketing approach than a functional problem.
