Lightweight super telephoto lens, capable of very good results
Clearly improved compared to the first version
Very light for the range it offers, handles very easily even on small bodies like the E-M10
In combination with Olympus' excellent stabilizer, it can provide stable images at low shutter speeds (for example, I have taken shots at 300mm with a 1/60 second exposure), something that is very difficult to achieve with other systems
300mm is naturally the weakest focal length, but it is very good at 250mm (500mm effective), which is impressive on its own, while between 75-150mm it is a real razor even wide open

For the price, weight, and performance, it is the absolute value for money at the moment

I use this specific lens on an Olympus Omd Em10ii camera and I can say that it perfectly matches its small size.
The range of 75-300mm (35mm eq: 150-600) is more than satisfactory for someone who needs a telephoto lens for close-up portraits or capturing wildlife subjects, etc. Its positives include fast autofocus, silent AF motor, and its small size and weight as a telephoto lens. Its negatives could be its aperture (f4.8-6.7) as it is quite dark, and when you need to quickly capture moving subjects such as birds (where a speed of 1/2000 sec or higher is required), you need to take this into consideration because you need relatively good light. The lens does not exhibit chromatic aberrations, only minimal ones in the corners around 150mm, and I believe the color reproduction is perfect. As for distortion, I did not notice anything. Referring to its sharpness, I would say that throughout its focal length, I consider it to be quite good, with perhaps slightly softer points at 75mm f4.8 and 300mm f6.7. The highest sharpness is observed at f8 from 75-300mm.
In conclusion, I would like to give my overall opinion that this is a very affordable telephoto lens, well-built, and quite small and lightweight, but with performance that can rival other bulkier and more expensive constructions. For the money it's worth, I am very satisfied with its zoom and sharpness, and I believe each of you will be too.

Very good zoom lens the Olympus M.Zuiko Digital ED 75-300mm 1:4.8-6.7 II.
Small in size and relatively lightweight, quiet thanks to the Screw Drive Mechanism and with fast autofocus operation. In terms of quality and value for money, I highly recommend it.
