Cheap ones are available for about a fiver and give decent images/video. They do fall apart after a while though, glass pops off etc. Also waterproof if you have an inquisitive mind...

Thanks, I am now looking into if my phone will "run" one though OTG usb, my phone has a midi setting when I plug it in to the computer as well as charge or transfer files.
Seems that there could also be a difference in depth of field between models
