Hi all, I'm trying (again) the stacked lens technique, this time with the 75-300IS with the 50f1.8 screwed on top with a self-made adaptor from two cokin adaptor rings (52 & 58 mm) The point is that I'm getting vigneting with it at the 300mm setting (less mm is worst). Is there anything I can do to improve this? (The aprox. magnification is about 6x) Greetings, Gerard. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
