On lack of fish and cancer - a tomato. EF / EF-S optics are large for EF-M mirrorless cameras. And this lens is thin and not very long. Everything else in the merits has already been indicated. Has some pros Pretty sharp across the frame. Moreover, at the maximum open aperture. Thanks to its optical quality, with its 320 eq. Mm it "goes around" lenses like the Tamron 70-300 at a focal length of 480 eq. Mm. Small level of chromatic aberrations. A good stabilizer, winning back up to four stops. While new, it spins very nicely. Cons: Plastic bayonet. f/6.3 at the long end. The STM motor does not set speed records. USM would be much more appropriate here. Complete set: only plastic covers. Price. The red price for this albeit optically perfect miracle is 15 thousand. at the current rate. It's being sold for 23,000.
