Panasonic leica dg 12 60mm f 2 8 4 vs panasonic lumix g x 12 35mm f 2 8 ii?
Both are stabilised, autofocus Micro Four Thirds zooms, so the choice comes down to range versus brightness.
The Panasonic Leica DG 12-60mm f/2.8-4 gives you more reach. On Micro Four Thirds it frames like 24-120mm on full frame, so one lens covers wide views through to tighter shots. The trade-off is that it gets darker as you zoom in.
The Panasonic Lumix G X 12-35mm f/2.8 II covers a shorter range, like 24-70mm on full frame, but stays at f/2.8 the whole way. That's the one I'd pick for dim rooms, events, or when you want more background blur.
Choose the 12-60 for a single lens that handles a whole trip. Choose the 12-35 for low light and a brighter, more controllable look. If the crop factor talk is confusing, the sensor sizes page explains it.
