i have been using a little sony dsc-f717 for doing a lot of nature photography and specifically insects. the camera has a decent lens and a 5x digital zoom. Now to get a good shot of a bug i have to get about 3 feet away and then use the digital zoom. the dragonflies i like to track down will not let you get within 10 ft much less the 3 ft, but occasionally i can sneak to about 3ft. unfortunately the camera may focus on the branch or leaf the insect is on so i take 5 or so pics and hope that at least one is on the bug i am looking to get the cannon 20d since it has a dot you can place on the object for perfect focus but it doesn't have the digital zoom so i have to be almost a foot away to get a shot which is pratically impossible. i have been tracking down the 100 or so species of dragonflies in the pensacola area and am up to about 50 and of course the last 50 are very wary Wanna kill these ads? We can help!
