Macro Lens for Table Top Videos?

This hasn't been answered yet, so I'll give it a try.

First, a macro lens technically means the image on the sensor is at least as big as real life. When it's the same size, it's a 1:1 macro. The 1:1 ratio is the actual size : the the size on the sensor. It also can be expressed as a 1x magnification factor. If the image on the sensor is bigger than real life, then it's a 2:1 or 4:1 (2x or 4x, respectively) lens. And some lenses call themselves macro, but don't meet the definition, such as Olympus' 50mm macro, with a 1:2 (0.5x) magnification. Note that the macro definition ignores crop factors, so the Olympus' 50mm 1:2 macro results in a picture much the same final size as a FF 1:1 macro lens (on a FF camera with the same resolution).

Now, there are two factors in how large the image on the sensor is: how close you can get, and the lens's focal length. A 12mm macro has to get about 4x closer than a 50mm macro would to get the same 1:1 ratio. And the opposite is true too: a wide focal length could have a very short minimum focus distance, but still not be a macro lens. Say a 12mm lens has the same minimum focus distance as a hypothetical 36mm 1:1 macro lens; the 12mm would have about a 3:1 (or 0.33x) magnification, and thus not be a macro lens. This is one reason most macro lens are of longer focal lengths.

All this to say, sounds like a macro lens isn't exactly what you need. I think you either want

A) a wide angle lens with a shorter minimum focus distance, or

B) a lens with a higher magnification (not necessarily a macro lens) than your's has and set up the camera as needed to get the view you want.

Both would be best, of course.  I'm not sure which lenses have shorter minimum focus or working distances, and higher magnifications on the short end, though. Sorry, not much help there.

And lastly, the 35mm Olympus lens you mention is an older four thirds lens, not a micro 4/3, so you'd need an adapter to us it, if you could find one to buy. It might give you a bigger magnification, part B) above, but I doubt you'd be happy with the angle of view.
