DCX condensor for Canon and Nikon Tubes
Condensers are used to reduce the hotspotting effect caused by light at the edges of the frame hitting the ground glass at a large angle of incidence.
You want to avoid marking your condenser lens; since it is very close to your focus screen blemishes will affect the image to a larger degree than marks on the achromat.
You should mount your condenser in the EOS tubes using a lens cloth to position it with the flatter side facing the GG.
This lens is perfect for use with canon EOS extension tubes or Nikon tubes.
