Extension Tubes in Macro Photography (Part III)

March 7, 2010

(Click here to go to this blog’s home page. Click here for Part I of “Extension Tubes in Macro Photography.” ¬†Click here for Part II.)

Miss Kitty's paw photographed with an 18-55mm lens and a 12mm extension tube. (Click photo once or twice to magnify detail.)


These three images illustrate the limitations of three different lengths of extension tubes. All three photos were taken with an 18-55mm lens in combination with an extension tube. From L to R: 12mm tube, 20mm tube, 36mm tube. (Click photo to enlarge.)

In my Kenko tube set I have three extension tubes: a 12mm tube, a 20 mm tube, and a 36mm tube.

I’d been meaning for awhile to experiment with the extension tubes. Last week when Miss Kitty walked by and rolled over exposing the bottoms of her paws, she instantly became a model. ¬†When I used the 12mm tube, I could get pretty close and focus on Miss Kitty’s entire paw (left photo of the tri-photo above). That was all the closer I could get with the 12mm tube.

When I used the 20mm tube, I could focus even closer on just two of Miss Kitty’s toe pads (middle photo of the tri-photo). Not all of the two pads are in focus, meaning, I think, I need to experiment more with camera settings and/or holding the camera steady.

I’d better post about something else before extension tubes wear out their welcome (if they haven’t already)! I have so much I want to post about that’s been on the back burner for awhile (for example, finishing up about Bill’s and my Oregon travels); yet I enjoy posting spontaneously about whatever topic is at hand. Thank you for sticking with the blog, never knowing what serious or absurd topic the next post will be about.
