I use Sigma 70-300mm 1:4-5.6 macro lens mounted on Nikon D40 for macro photography. As I wanted to enhance (not satisfied with 1:4 macro) I bought a set of close-up lenses ( +1, +2, +4, +10). I have taken few photographs using Sigma Macro + close-up lense combination, but the focus is not proper.

If someone in the forum have used this combination, please let me know

how to get the best results

any pictures they have taken

any links for tutorials on this aspect

Thanks for your help.

Cheers,
