Got my reversing coupling ring today so I've attached a 55mm lens in reverse onto the front of a Sigma 150mm macro lens to see what it can do. This is a Small Copper butterflies eye which I would guess is about 1.5-2mm wide. Lighting still needs some work as I had to shoot at a fairly high ISO and had to noise correct a lot so plenty of scope for further improvements. Just wanted to see what it could do. This is a fair crop of a 25 image handheld(but braced) stack.
