Thanks Neil, here are two pictures. The kingfisher with the Sony 30mm f3.5. (manual focus) The Great White Egret with the Nikon 50mm F1.8 D (distance 30m) This lens is cheap and is of excellent quality. The lens needs an adapter for Nikon mount. The kit lens of Sony 18-55 mm is not recommended. The vignetting is too big. I use a Swarovski adapter UCA
