Hmm PoPok, i think apart from hand shake, the focus is slightly off. If you look carefully, the protrusion of the eye further from the lens seems to be in focus. Still a nice shot nonetheless
Ocellatus, it means that the shutterspeed is too low. Try using a tripod or put the camera on a stable structure, it would help alot. Also, squeeze the shutter, don't press down suddenly. Although this may not seem really important, in macro, the camera movements are amplified so it's best to do so yep.
The shots of my betta fry and taken in super macro mode with my lens zoomed in all the way, so I'm not sure if that statement really holds. Pardon my ignorance if its true! Cheers
