That's cheaper then the 7artisans 55mm, probably just as shitty too. Maybe slightly more shitty.
Never did try my manual micro 4/3 mount lens on my new camera. Probably won't either. Oh wait, I think my sister wanted it with the camera I'm selling her. That's probably why I never bothered trying it.
In fact, I probably won't use my new camera. Guess I don't need another battery for it, or a grip.
It's $75 on Amazon.
