hi, i noticed recently that there are 3 black tiny spots found in my lens. I tried using a blower and wiping with a microfibre cloth to no avail. Is it possible to be fungus? but from what i know fungus would be white in colour and this spots seems like dirt on the surface. Please advice on how to remove them and if a cleaning kit is necessary? i use my camera quite often and its still quite new, so i doubt that it would be funguses. Thanks in advance
