Macros with a Reversed Sigma 18-50mm f/3.5-5.6

Kevin shows that all you need for a successful series of macro shots is a rubber-band, among other things.

The method used is similar to Arne’s, but this time, it’s the el-cheapo Sigma 18-50mm f/3.5-5.6 DC lens that’s being reversed, rather than the el-cheapo Nikkor 18-55mm in Arne’s case. And Kevin uses a rubber band to hold the front of the lens flush against the lens mount of the D50. I happen to own (since April 2004) this very same Sigma lens myself, but have never thought it could be used this way — until now, that is.


  1. View Kevin’s images in all their glory, and read about the method
  2. Step-by-step explanation of the lens reversal process
  3. Aperture lever on the Sigma 18-50mm f/3.5-5.6 lens
  4. Since the Sigma doesn’t have an aperture ring, the aperture sets itself to the smallest opening when not mounted onto the camera. This causes difficulty for focusing because so little light gets through to the viewfinder. So, when focusing, slide the aperture lever to enlarge the aperture opening, focus (move your body back and forth until focus is achieved), and release the lever before the shot is taken.
  5. You have to move the camera to track and maintain focus on the moving bugs
