I'm looking to get a macro lens to take pictures of bugs and such without breaking the bank. I've rented the 100 2.8 USM in the past for bee and lizard shots and I found it to be a great lens.
I've been reading up on macro photography and came to the understanding that it works in reverse of normal lens. The wider the angle, the more the magnification.
I've looked at a entry macro lens with extension tubes to increase magnification and http://www.cambridgeincolour.com …tension-tubes-closeup.htm explains that while a 60mm will have a closer focal distance, with extension tubes it will actually magnify more than the 100mm. Am I correct in my understanding of this?
So, does anyone have practical experience with the 60mm vs 100mm in terms of ease of use, focusing distance, and extension tubes? If I could afford the MP-E I would, but for now only the USM lenses are in my price range.
