So, I did a kitchen counter experiment.? Using kitchen lights and a shiny dime, I first combined the dedicated extension tube with the 2X extender and mounted the assembly on an old Star-D tripod.? I adjusted the height so that the image of the dime filled the height of the frame, and took several exposures.? Here is the resulting image: http://www.gallery.leica-users.org/v/OldNick/20201008-DSCF2180.JPG.html I then removed the 2X Extender and mounted the lens and extension tube as it was intended to be used.? I took several images of the dime, which now filled about half the height of the frame, and cropped the resulting image to match the first one: http://www.gallery.leica-users.org/v/OldNick/20201008-DSCF2192.JPG.html It is my opinion that the lens/tube combination is sharper without the 2X Extender, even with enlargement.? I am ignoring differences in lighting with this setup. -- Jim Nichols Tullahoma, TN USA
