Thanks IPVM team for your thorough review. It's becoming increasingly difficult to distinguish features from one top-tier camera to the next, yet this report is very well detailed.

My impression is Hanwha is the real dark horse here. The one bringing the best value of performance and price combination in the mid to upper tier. As a long time Sony dealer and proponent, this is disappointing.

As I use to work for Hanwah SAMSUNG (Sole Distributor in HKG) for more than 5 years, and now I switch my role back to SI. I do find both quality and performance of SONY and SAMSUNG are near. But in some real case of project, and I find SONY is best outcome than AXIS and SAMSUNG.
