I have the 25 mm tube, 50/1.8 and 28-105. Results of the 25mm tube on either of these lenses is quite good to my standards. With the 50/1.8 you can autofocus in bright light conditions, with the 28-105 I can forget autofocus at all. I've made some good pictures using the 25mm + 50/1.8 handheld (in bright light). Advantage of the 28-105 is that the focussing range is larger due to the ability to zoom. When I use the 28-105, I set the focus ring to a center position (about 1 meter?), and then turn the zoom ring to focus. Then I use the focus-ring to fine-tune the focus. I think the combination with the 20-40 is not usable at the short end. (Your maximum focussing distance will be so close, that it's actually _in_ the lens) Stefan. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
