Patrick, Fz1000 is a very good choice. So good I gave up with Canon and collection of zoom lenses. I generally stick to Aperture or Shutter modes but if you need just a little more zoom without using digital trickery the Intelligent Auto mode is also excellent. As always read the manual, you can alter lighting settings in an instant re sun and gloomy weather and I prefer using viewfinder with horizon display. I use vivid colours option. The video option is extremely good.
Have just uploaded DHT PHOENIX (only one on site) taken with Intelligent Auto at range of 1.7 km. Still a bit of zoom in reserve. http://www.shipspotting.com/gallery/photo.php?lid=2521027
