Re-Learning

Oh my.  I haven't been using my 100mm macro lens for a while and I think I need to relearn how to use it.  There was frost this morning and I love this leaf, but it seems a bit out of focus to me.  I'm not sure why it would be, because I certainly wasn't too close.  And I thought I was focusing on it. Not sure what happened, but when I realized it, the sun had melted the frost, so this is the best picture I got.
