For the price this lens is hard to beat if you want full coverage of an MFT sensor, as it's small but built like a tank it's hard to find anything in this price range. The lens is surprisingly sharp wide open and at f2.8 it's still useful in low light. I've used this on both my GH5 and GX85 and both have been great, although the lens is so wide it's almost impossible to keep your fingers out of the frame on the GH5. Pro tip: if you're using the GH5 and want full-circle video, switch to anamorphic mode and you now have a full 180-degree field of view for 6K capture.
