You got that right, I wanted to write but didn't.
The truth is that I like learning hard things, like my still-feels-new camera and still-newer macro lens. So far, both have outscored me in a contest of skill.
But today's morning foray and some cooperative odes provided a much more successful than usual shoot. I am beginning to think I should just use this lens and forget the other one. I am finally discovering the "sweet spot."
