Finally managed to get one of those cheap cost effective add-on lens and took my first macro with a macro lens. It's part of a wide-angle lens where you unscrew the front element and it becomes macro. The lens pair cost RM38 and I got it from Typo. This one comes with a clip mechanism so it's independent of any phone cases.
And it's with this that I realised how difficult it is to take macro photos. Any slight movement would make the whole photo either blurry or out of focus. =.="
