If you are looking for an affordable way to get up close to your subject, the Nikon Coolpix P900 could be it. When I say affordable, it's all relative.
You could spend more than €2,000 on a DSLR body and a half decent lens; or you could go for this 16 megapixel camera with an 83x optical zoom for less than half the price.
At €649 it’s not exactly budget, but it punches far above its weight, shooting full HD movies, vibration reduction for steadier images and a rapid autofocus that makes sure your fast motion footage will stay in focus.
It also has some nice extras like time lapse movie, a moon watching mode, and full HD movies at 1080p, 60 frames per second. nikon.com
