If there’s one essential item for macro photography, aside from a macro lens (or extension tubes), it’s a macro focusing rail. We’ve featured a few focusing rails here on DIYP before, like the NiSi NM-180 (review here), as well as some other DIY solutions. This one, from Curious Scientist, is an ongoing project based around an Arduino Nano that uses a stepper motor to move your camera along a rail in fine increments.
I say it’s an ongoing project because since releasing his first video on his motorised macro rail slider only a month ago, he’s already posted an update showing almost a complete redesign of the staging platform on which you mount the camera. Depending on your camera and needs, either design might work very well for you, so I’ve included his videos below for both of them.
