I received this Quick Release plate from SmallRig about two weeks ago and have been putting it through its paces.
The large Quick Release arm is well made and very responsive, you have to turn it a full 180º to release the tripod plate but that no great hardship.
Its refreshing to have a QR plate that allows quick access rather than the usual two position press a button as seen in most QR setups.
I love the small foot print that you get with the smaller tripod mounting plate, great for my Panasonic GX8.
This is my poppadom shot taken with my GX8 and 18-30mm f1.4 Sigma ART lens on a Canon mount Metabones adapter taking the f1.4 to f1.1
