DIY macro?

[grainy]

Hi folks -- has anyone every tried a DIY macro setup, like folks often do with Holga still cameras? It's often as simple as just taping a macro lens or even magnifying glass to the front of your camera lens.
No one talks about doing this with movie cameras -- is it because of the availablity of macro lenses, or is there an inherent problem so horrible that it nullifies this idea, or is it that it probably would produce results below image quality expectations?

Just curious!

Unsurpisingly, since a camera is a camera, it works for Movie and Video cameras also.No magic involved!

Of course you can if you can mount the optics.
One thing to remember - magnifying glass is mainly a positive convex singlet lens. With positive convex lenses maginification occurs when the object is at a distance from the convex lens that is LESS than the focal length of the convex lens. The magnified image is what is refered to as a Virtual upright image that can be focussed by the main lens.
I use a convex doublet lens with a 75mm diameter and 200mm focal length in front of an anamorphic lens. These are called achromatic lenses.
Even with a low quality lens you can create some great effects via what is called color separation exhibited with a low quality convex lens.
If interested we can discuss more!
