Thanks donuss and paqart. to paqart I like taking picture dandelion. Why? I don't now. It's lens Carl Zeiss 50mm/2 ZK - namely Pentax K-mount. It's crop. I take picture without tripod. About sharpness: Maybe I can already feel the CZ lens ZK, Pentax camera and dandelion. Maybe it's Pentax K-30 + Carl Zeis lens effect. But sometimes I add sharpness in Adobe Photoshop Elements 11 before publication. Here too.
