I have a question for all of you experts (or not so expert). I was desperate for a good macro lens but the prices are just too much at this time. After reading some different posts on the subject, I ordered a set of the Kenko extension tubes. Has anyone had experience with these and if so what is your opinion of them? I have tried them a couple of times and wasn't real happy with the results. As I am also a newbie at all of this I can't decide if I should continue to try them and hope for better results or send them back and save up for a good macro. It's very possible I'm doing something wrong in my use of them. Now for a stupid question, so nobody laugh out loud. If all the tubes do is extend the lens and has no magnification shouldn't they also work to extend my telephoto lens.Or were these tubes to be used as an extension just for an existing macro lens? The directions I got with the tubes were next to useless and I can't really find more info on the net. Even though the tubes were a lot less expensive than a new lens, it's still a lot of money to me. I use a Nikon D40 and love the camera so far but I really love macro work and wanted to get better shots. Thanks in advance for any help you can give me and I hope this isn't posted in the wrong place.
