Extension Tube Experimenting

Desert flower found in Palm Springs, California in an empty plot of land across from the Palm Springs Convention Center.

Taken with Canon 5D with a Canon EF 70-200mm f4L IS lens mounted on a Canon EF 25mm extension tube, and then using both the distance from the subject for size in frame and then zooming to focus, this technique takes a little to get used to.

Using an extension tube with different lenses will produce very different results, but you also have to keep in mind the lens being used.

For anything under 25mm, for example, the subject will not be in focus when using a 25mm extension tube because the tube pushes the focal plane forward by 25mm. At 25mm, the front of the lens will practically be touching the subject so be careful when moving closer to a subject, especially if it can potentially damage your lens.

I have a few lenses with me on this trip to experiment with so keep posted for other combinations and how different the results may be.

    Very successful! I have a lens 18-200mm and many times I took close-ups with full zoom from “distance”.

    Happy Sunday!
