As a retired real estate appraiser, I have a deep appreciation for all that a quality bridge camera can do. We’ve owned a Minolta rangefinder, two Olympus cameras, and three digital Panasonics - most recently the FZ300. After using it for several years, I would recommend the FZ2500 due to the larger sensor. Yes, it is a heavier camera and not quite as convenient as the FZ300. But I am frequently frustrated by the noise visible above ISO 400. The other frustration with it is the lack of sharpness in my images. I’m not sure about the main cause. I’m seriously considering an upgrade to the Sony, but the cost, weight and my small, arthritic hands keep me hanging on to the FZ300. Good luck!
