Close look filter.
People have always been curious. That played a great role in the process of evolution. Humans always wanted to know what is inside the things around them, how it works. That made macro filters so popular. With the help of it people can get a closer look and catch more details.

Keep your lenses clean. Means of cleaning and maintaining the optics of the slr camera.
The most important and expensive part of the slr camera is the objective. So maintenance of it is a big deal.
If you got anything on your objective, blow it off with a bulb or brush it off. Touching your lens with fingers is not recommendable.
Only for glass optics: If you got any fat smudge on your lens, wipe it off with a napkin or a tampon moistened with an alcohol-ether composition
Don’t ever use any liquids that weren’t bought in the special photo shops. Different types of detergents, window, glass cleaners are not acceptable.
