Haven't tried this, but you've certainly piqued my interest. I like using
extension tubes with longer lenses for portrait work, for reasons you
describe. Turns a busy background into a nice "awash" backdrop, even with
smaller apertures. I haven't tried using tubes with my 400/5.6, but you've
convinced me to try.

No there isn't any such thing but on a recent trip to Yosemite some plants
were inaccessible unless I used extension tubes on my fave lens, the 400mm
f/6.8 Telyt.

The really cool thing about using such a long lens for closeups is the
backgrounds - they turn into a clean wash of color, and by shifting the
camera ever so slightly I can get a completely different area in the
background, which may be a very different color.  (Kodachromes in a few

Just for jollies I threw every extension tube I have on the 400 to see what
kind of reproduction ratios I can get.  I used a 14198, 14256 and 14182,
plus the 60mm extension of the 400's focussing mount and the total extension
is 180mm, for a reproduction ratio of 1:2.2.  Subject-to-film  distance is
about 6 feet.

Has anyone else done this?
