Any of the cameras you listed would be acceptable.
I would visit a camera store and try each one. ( a camera store, not a department store )
All of those camera have a stabilized lens... but...
You really cannot hand-hold any camera at full zoom and expect the best results. 10X is just about the limit for hand holding a camera. You need a tripod for those 50X bird pictures.
Also, your macro shots are best done with a tripod.
I'm hoping to get some advice on which camera to buy. I'm looking for a superzoom bridge camera and am having a hard time choosing.
Primary use: This is mainly for my yearly vacations on the Magdalen Islands, where I photograph birds in forests and on the shore. (Weather is of course variable there; equally bright sun and overcast days.) I also take photos of landscapes, night skies (constellations) and wild plants, and sometimes people. I share my photos on a blog, but I don't make photography the primary focus of my vacation moments.
Priorities in order of importance to me:
1. Clear superzoom capability (at least 50x zoom) for identifying birds
2. solid image quality
3. fast autofocus
4. reliable image stabilization (I have a slightly shaky hand)
5. decent macro capability
6. decent viewfinder
7. general ease of use.
Is there a camera that you would recommend more highly than others? Any cameras that you would suggest I avoid? Any advice at all would be greatly appreciated.
Thanks very much.
(P.S. Some that I am considering so far are Canon PowerShot SX60 HS, Nikon Coolpix P900 (or B700), Panasonic DC-FZ80K Lumix, Sony HX350...)
