Old and biased opinions about sensor size are still coming from the uninformed. New technology is providing great image quality from the super zooms at a fraction of the cost and weight of a DSLR (I own two). Go for a super zoom with flip out screen and viewfinder. My favorites are Canon.
I am not able to get down low but just sitting down makes a difference!
I'll keep my DSLR because the last time I went to Arizona I took a super zoom and I missed the responsiveness of the Sony DSLR when it came to BIF and airplanes in flight.
