If you don't mind to loose 2 stop at macro 1:1.
this lens is not a constance f2.8 it will be f5.6 at 1:1.

benedium said:If I'm not wrong, all macro lenses, even Canon or Nikon originals also cannot maintain constant aperture as you change focal distance.
This is a characteristic of all macro lens, aperture gets smaller when you zoom in to 1:1. prob to accomode the DOF at that focus length. Imagine f2.8 dof at 1:1 reproduction :sweat: man that is some blur pics.sharp_shooter said:ATX 100 ProD is great, construction wise is so solid, also with the pull and push mechanism it is easy to use manual and auto focus.
