Hello David,
I have no knowledge of such a convertible monopod. But
this looks definitively too flimsy to me.
The question is, what do you want/need to achieve:
- A little more stability for handholding? Take a
monopod.
- Something that can stand up securely beside your wheelchair? I know the kind of microphone stand that has tree legs on the bottom that are around 50cm each. That
could be stable enough. But I'd not mount my precious gear to a construct with a smaller base.
- Something to mount to your wheelchair? Perhaps a
gorillapod might do the job.
- A support for stabilizing the camera that does not need your chair or the ground? There are sort of "supports" that you mount to your camera and press against your chest. This is often used with video cams.
Unfortunately my only experience is with tripods and monopods.
