These were taken with a standard kit zoom lens, in this case a Fuji xf 18-55 lens, with an extension tube that allowed close focus. I have a set of cheap extension tubes of 11mm and 14mm from a generic Chinese source, JJC. This technique of using a zoom lens with an extension is not considered best practice, but it works. I printed the left image as a card at 5×7 and it looks very good.
I sold my Canon 100mm macro and the and the adapter for it to mount it to Fuji cameras. I thus reduced my travel kit for macro photography from carrying an extra lens and adapter to carrying around two very small tubes.
