I find this to be a tough choice. The bigger sensor of the FZ1000 vs the constant f/2.8 lens, longer zoom, touch screen, and weather sealing of the FZ300. If I were choosing my primary or only camera I suppose I'd go with sensor size, but thinking about one of these as a supplemental option is tough. I really like some of the extras on the FZ300, and have other options when IQ is paramount. So, please add your voice. What would be your pick and why? Assume that the cost is more or less the same. Thanks.
