While Heather spent her time testing the new Panasonic G7 at the Erddig National Trust site, I concentrated on the new Lumix 42.5mm f/1.7 lens. As with the G7, this can also be categorised as a mini-review. My time spent with the lens wasn’t any longer than an afternoon but enough to write more than I did for our hands-on review from the UK Photoshow in March.
