Speaking as a SX50HS owner, the camera is very good for documentation and travelling use
I mean, you can capture anything as long as your eye can see. No matter how small or far the (bird) subject is.
The only problem is; unless it is bright and clear day, most of your pictures will be soft.
After learning to step up ISO, shuttle speed, EV compensation, my hit rate of getting a reasonable sharp image has increased.
You have to shoot in RAW and do alot of post processing in order to have more sharper images after a day of shooting.
Not sure how are the other superzoom bridge cameras fare in terms of JPEG picture sharpness.
Can the users care to share?
