At first, the class didn't recognize it without reading the name—they thought I had captured something unusual. But upon closer look, they realized what it was!!!!!
To me, it looks absolutely stunning.

Good day! That's awesome! If you don't mind sharing, what HFR do you get with your MC DUO + C11 x0.7 combination? I'm currently setting up the same combo myself and want to know the benchmarks)))

There is no secret, but I have never measured this parameter and am not aware of how to measure it.
