I know you are supposed to eat the fruit, but I couldn't help myself.  I just HAD to play a little.  I got new Zeikos macro extension tubes for my 105mm lens, and I can't believe how darn close I can get.   I had so much fun doing these.  I used the 105 with extension tubes, 1/125 @ f/8.0 and ISO 200, flash set to TTL bounced off the wall beside me.  Thanks so much for looking.
