ePhotozine spotted the Panasonic 10-25mm f/1.7 lens at the Photography Show 2019 in Birmingham.
The lens extends slightly when you zoom to 25mm, and the closest focusing distance is 28cm. The lens on display is a working pre-production sample, so we were unable to take sample photo using the lens, however we can tell you that the lens works very well on a Panasonic Lumix G9, and focus was rapid. The aperture ring on the lens we used is clickless, which means it’s silent and can be smoothly adjusted, perhaps indicating that the lens is specifically suited (or rather designed) with video work in mind. The lens zooms smoothly through the zoom range, and has a 77mm filter thread.
