Just bought the raynox DSR250 macro lens and toyed around with it on my S3. I had a really hard time trying to maintain the correct distance and reduce hand shake to get a good picture. So far, the results were not satisfactory. Are there any tips to get a good macro picture? When using a tripod, isn't it cumbersome to move the camera and the tripod a few millimeters to focus properly? The pictures below are some of the better ones. Please advise.
