I am new to photography. I am really interested in taking close up photos (macro photography) of objects with a blurry background. But my mobile phone (a Sony Xperia Ion ) does not have the facility to adjust the aperture size. It's fixed to f/2.8 or something. So, I learned that blurring the background is not possible with this mobile camera.
Will attaching one of the mini macro lens now available for mobile phones (like this one) help with taking background blurry (macro) photos?
