I decided to take a walk in the park with the A7r4 and the G Master 100-400 not realising what a fantastic bit of glass this is not only sharp for wildlife or sports it makes a great portrait street or just a walk round lens. The light was poor so i headed for the water fountain. It was winter so the fountain was frozen and the water in the fountain was solid so could not test it full. Being very quiet i just looked around and notice the statues surrounding the fountain. I used just the settings i would use for my wildlife so it was only when i got home and looked at how sharp the images together with the 61mp on the r4.

Just take a look at the detail in Black and White this amazing camera and Lens can produce. Please feel free to message me if you need me to test the lens on anything else i would gladly try.
