Coupled Reverse Lens Adaptor for Macro Photography

3D Print your Macro Photography

In Brief

This adaptor allows you to take macro photographs with Canon EF or EFS lenses. It was designed with kit zooms in mind. All examples use a kit 18-55mm and 25:250 kit zoom.

The Series

The adaptor is part of a collection of 3D printed macro photography tools:

• Reverse lens adaptor. (Here) *Lens hood for reversed lenses (Included in this Thing). *Diffuser for reversed lenses (Included in this Thing).
• Specimen/object mount (Here). *A coupled reversed lens adaptor. This Thing!
• Macro tube kit (Due Sep. 2001).
• Box to carry adaptors (Due Sep. 2001)
• Manual slider rail for focus stacking (Due Oct 2021).
• Fully automated slider rail for focus stacking (Due Oct 2021).

• Micro adaptor (In planning) All tools are detailed in a series of Instructables called 3D Print your Macro Photography

  How it works

---

This is a variation on the Reverse Lens Adaptor. This adaptor reverses the lens's direction, which gives it magnification and attaches it to another lens that acts as an extension tube that increases the magnification further. With two Canon kit zooms, I got up to 14X magnification. Generally, the quality is higher than the single reverse lens, but the quality falls off at the extreme end.

How to use it

You will need two lenses of different focal lengths.

1. Mount the longer lens on your camera.
2. Set its focus to infinity and the aperture wide open
3. Screw the adaptor into where the filter would normally go.
4. Screw the second shorter lens onto the other side of the adaptor so that the lenses face each other

5. Move the camera back and forward, or use the front lens to focus A detailed Instructable is available.

   ### Reverse Lens Hood and Diffuser

   The reverse lens hood isn't essential but stops stray light from entering the lens, protects the delicate rear element, allows you to attach filters and the diffuser. You can also add reflective material that helps light the subject.

   The diffuser mounts onto the reversed lens hood. It's designed to deflect light from above and behind the lens onto the subject. It's most valuable when used with the internal flash.
