[Leica] IMG: Macro Experiment with Leica-R 60 Elmarit Macro Lens

[Lluis Ripoll]

I agree, the second image is sharper, but is the Extender 2X the Leica one? I think remember that Leica has made a second 2x Extender APO….

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:
