Will Sigma mc- 1 1 connect the lens indicator?

When a fully supported lens is connected (for example, the Sigma lens in the official support list such as 35ART), the MC 1 1 indicator light will light up for 5 seconds after the machine is turned on.

When connecting a lens that can be fully supported after upgrading the firmware (for example, 50ART band 1.0 firmware), the indicator light of MC 1 1 will flash for 5 seconds after starting.

When connecting a completely unsupported lens, such as Canon, Longteng or an older Sigma lens, the indicator light is completely off, which means that the hybrid focusing function of the fuselage cannot be called, but the slow contrast focusing and electronically controlled aperture can still work.
