My Petzval Russian lens has its own mind about focus, it picks pretty much what it wants to focus on, I am never sure until I look in the computer. I like the way the lens captured the intimacy of our morning chores, a special time for us. The donkeys love to be brushed and sit patiently while Maria combs their usually dirty and matted coat. They seem to need attention, and then go about their business. Donkeys are loving but not needy, like pets.
