Best budget lens for the panasonic lumix g97?
For a budget lens on the G97, I'd start with a fast 25mm. It frames like a 50mm on full frame, which is the sensible first prime the first camera guide recommends for people and low light. My pick is the Panasonic Lumix G 25mm f/1.7.
If you want one lens for everything, the Panasonic Lumix G 14-42mm f/3.5-5.6 II is a simple, light kit zoom. For a cheaper prime to try, the 7Artisans 25mm f/1.8 is worth a look, though it's manual focus.
