One of two lenses for mft (the second is 35-100 / 2.8), which has no analogues for me in other systems. I recommend. There is a version of dji for drones on sale, you can find it cheaper. Pros below: Great picture, sharpness already from 1.7. The size is perfect even for the baby gm1. Has cons: The aperture ring is too sensitive, it easily flies off A. Personally, I don’t need it at all - I’m used to adjusting it with the rear wheel on the camera.
