Strange report. He says the adapter has an USB connector for it's own firmware. To me, it would be logical that if I buy such an adapter, I can use it instead of the dedicated dock from Sigma to update my lenses as well, but he does not tell a thing about he DID update them. At the time he put his report online, there were couple of updates available for his 24/1.4 and 150-600 Sports as well.
