I like bird photography more and more. Here are some recent pics with some birds in action

Not the sharpest, hard to focus manually, but it doesn't show any color aberrations and it's small and lightweight compared to the novoflex bazooka. Unfortunately the 1.7x AF won't autofocus with this slow big glass. Toine
