A 2X converter results in half the depth of field and depth of field gets less the closer something is. I suppose the rule of thumb would be if using 2X then don't photograph anything too close. As a guide, at about 20m I can get all of a Pigeon in focus with the barlow.The 2X Kenko should be fairly versatile because you can put a cheap macro tube between the camera and teleconverter to alter its magnification. Something like a 35mm macro tube would take it to around 3X for example.Paul.</blockquote>
