Originally posted by madbrain How do you use it with lenses that are not listed ?
Normally, you can't. If the lens isn't available for your camera body, it isn't available. See:
Supported equipment
to confirm what they have atm
However if the lenses are equivalents (eg Tamron/Samsung/Pentax 18-250, Pentax DA 55-300/DAL 55-300), DxO just detects it. You can also sometimes get a lens ambiguity come up that might convince the software to treat one lens as another, but I haven't seen that work in recent versions.
