Macro is always a popular photography subject. Even if it’s not something you shoot all the time, it’s something that pretty much all of us will have a go at given the chance. But macro lenses are expensive, so it’s not something that a lot of people will try, even if they want to. There are less expensive options out there, though, especially if you own a 3D printer.
We’ve featured photographer Nick Sherlock and his 3D printed extension tubes and macro accessories before, but this pair of extension tubes is particularly interesting. They’re variable extension tubes with ranges of 0-35mm and 50-150mm, designed to let you adjust their length to whatever you need using Canon EF mount lenses on Sony E mount bodies.
