  Dear ZJ2000,
  
  I need to ask something before decide to buy the tubes & TC
  
  If only use Kenko Uniplus 25mm extension tubes, how much loss of light will occur ? Only 1 stop ? (from f/2.8 --> f/4 ? )
  If only use Kenko Pro300DG 1.4x TC, the loss of light also 1 stop ?
  
  So if use Uniplus 25mm extension tubes & Pro300DG 1.4x teleconverter together, the total loss of light will become 2 stops ? (from f/2.8 --> f/5.6) ?
  
  Is it correct ?
  
  Thank you,
  Jeff
