I bought a set of extension tubes today (Rokunar 13, 21, and 31 for Maxxum) and decided to play with some non-typical macro shots tonight.
I used a 50 f1.4, 50 f3.5, 100 f2.8, 135 f2.8, 500 f8, and a 70-200 2.8G. I got a little bored early on and upped the ante by stacking all of the tubes on top of a kenko teleplus pro 300 ×1.4 on top of a kenko teleplus Pro 300 ×2. Dragged out the giant tripod and I was good to go.
While absolute sharpness and a lot of light were missing (used my 56AM flash), the results turned out much better than expected. EXIF should be intact below images to see which is which. I didn’t bother cropping down, so the images are the fullsize view resized to a max 800×800.
