Wasn't the best of days to be testing out the new teleconverter but had to
see how it worked. Had the flash on for the first shot (batteries died shortly
there after.) All the photos were shot at full zoom and wide open. The first
3 shots were manual focus and then the last shot was autofocus using the
tape trick. (The SP acts just like the Canon teleconverter.) The first and last shot
didn't need much more sharpenning than usual. The next two needed a
touch more. I need a session with some good light before I draw any final
conclusions.

All shots 20D, 100-400L, Tamron 1.4X SP, hand held

This is the shot I got before the flash died.
ISO 400, f/8, 1/250 sec, 420 EX, 560mm, manual focus



ISO 800, f/8, 1/500 sec, 560mm, manual focus


Then, I encountered this groundhog on a trail I was walking
ISO 800, f/8, 1/640 sec,560mm, manual focus


Then there was this guy. Haven't posted one of these in a while. I guess
this guy illustrates where the term "chipmunk cheeks" comes from
ISO 400, f/8, 1/40 sec, 560mm, autofocus (tape trick)

Thanks for checking out the photos leeanne and for your comment. The
groundhog actually suprised me. Usually once they spot you, they scurry
off into a hole or into the brush, never to be seen again.

I couldn't choose a favorite here Woodmeister as they are all excellent. Very good. What is the tape trick, never heard of that.

Thanks houston. The Tamron 1.4X converter acts exactly like the Canon
in respect to disabling the autofocus for any lens slower than f/4. Taping
three of the contacts on the converter somehow prevents the camera from
knowing that. However, the effective apeture setting (converter + lens) isn't
reported, just the lens setting.
