Finally getting the right distance to get better zoomed in shots using this new cam hehe.

Here's how it sounds using my old lipoly battery.Haven't completely finetuned this awesome akm which was shouting OPEN FPS the moment I saw
it hehe so will update this review further once I'm done with it.
Tnx for viewing.
