For a very long time, I have been wanting a longer focal length true macro lens.  I finally ordered a Tamron 180mm 1:1 macro.  I was somewhat concerned because a friend said he had a similar lens and rarely used it because the long focal length meant too much movement to handhold it.  I did some shots holding it by hand, and it worked fine.

Although not super close, this one is certainly sharp for a hand held photo.  I noticed a ladybug on what was left of my dill plant and took some shots of it.  When looking at them, I could see the reason it was there – aphids.
