Hi Ben, The A-series or even the P-series filter holder can cause vignetting if you rotate the holder to a 45 degree setting. Tricks like removing the outer two filter slots, or WJM's suggestion of mounting the P holder onto the EF 20-35 lens-hood bayonet mount work fine if the filters are mounted vertically or horizontally, but fail if using filters diagonally. So, if the A252 Filter-Holder Cap is the reason you live dangerously by leaving the A-series filter holder on your lens, have you considered using the A253 Ring cap instead? http://www.cokin.fr/ico4-p1.html Cheers Julian Loke * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
