I need to replace my MD mount adapter it was very cheap(around £5/$8) the mechanism doesn't sit in place without it being prodded before putting it on the body. It is a little loose even then.
what sort of price is reasonable for a decent one? What are the signs of decent ones?
What is tthe benefit of a speed booster?are the metabones and zhongyi any different?
