So I custom built this camera belly rig *Photo 1* and this issues is that i'm having is that when I attach my Sigma 10-22 because the camera body base sits lower (Canon SL1) then most cameras I have had to use the custom mod in *photo 2*. Then sometimes when I use my canon 50d mark iii on my zeiss otus lenes I have to dissemble everything. My question is does anyone know of a base plate for a 15mm rail system that can give not only forward and back adjustment but also up and down? It's beginning to get on my nerves
