There is no way I can match the exposure and processing mastery of Ronny or George, but compelled as I am to play with lenses, photograph, process and post, here with the 7.5mm is ground-cover galore!
This lens is nowhere near as sharp as my 8mm 2.8 or as resistant to flare, and it cannot be focused at all BUT it is small, easy to handle, set at f/16 and use the screen on the Z6 and shoot away. Add a little sharpening at the end to compensate for the aperture.
