Good Evening (well it's evening here), Ok, here's the scoop. As I posted here earlier, I have been kayaking the local streams and lakes. Along the way I encounter some incredible wildlife. Most amazing are bugs that I've never seen before. I would love to get some shots off of these creatures. What would the "best" lens options be? (I know best is a loaded word, I guess I want to know what would produce images that would fill the frame even if I'm a few feet away?) Here is what I currently have Canon 70-300mm 4.5-5.6 USM Canon 70-200mm f/2.8 L Canon 50mm 1.8 EF-S 17-55mm Canon 20D. The range of distances I encounter these bugs varies greatly. Most dragonflys are content to land on the bow of my boat and drift with me, only inches to a few feet away. Most spiders are on logs I pass by, maybe a foot or so away but I can either anchor or hold on to the log to get very close, maybe six inches or so. Some other bugs are on the water surface not necessarily close and these bugs can move. Now the question. What would I be better off using to capture images of these bugs that will fill the frame? Use just my telephoto lenses and get as close as focus allows? Buy either the 100mm or 180mm L Canon Macro? Buy some extension tubes and use them with my telephoto lenses? Buy both extension tubes and a new macro? I've never been a big bug fan, but seeing some of these things I've never encountered before has piqued my interest. I'd love to grab some pics of these things to identify the bug, make a possible local calendar (my town eats these sort of things up), and to just take some cool pics. I'm not looking to spend a fortune but I am willing to make an investment if it will produce what I'm looking for. Suggestions are greatly appreciated. Thanks in advance.
