thanks everyone. The Lange's was smaller and tougher to get than I thought, and focusing was hard with all of the twigs and leaves in the way. The Canon 24-70 2.8 is a great lens, but my Tamron 16-300 might be better for macro? Anyone have experience with that?
I don't own a macro lens. All of my butterfly, dragonfly and bug shots that you see here were taken with telephoto zooms, lately my 150-600 Tamron, previously with my Nikon 75-300. To avoid the AF getting confused and not knowing what to focus on, it is best to use single spot focusing.
