Compatibility with an SLR camera depends entirely on the lens used, as SLR cameras have interchangeable lenses. The simplest solution is to use the Optic with the following:
  • A good lens, with good depth of field at close distance, and a zoom that travels through 45-55mm. (e.g. 18-55mm, 28-70mm, 28-105mm lenses go through this range)
  • A close-up diopter (~$25-$30), may be needed to allow your lens to focus more closely. (Many SLR lenses cannot focus closer than 0.5m/1.6ft).
  • A stepping ring (~$8) may be needed to match the filter threads on your lens to the Optic. The Optic can come with 52mm, 58mm, or 62mm threads.
We have samples with different combinations in our Gallery.

A zoom lens makes image adjustment easy. The added weight of our Optic may tend to backdrive the zoom when pointed vertically. A thick rubber band works great to hold the zoom in place. (No need to engineer a special clip...A rubber band is soft, won't scratch your lens, has a good grip, and highly adjustable!)

We believe this setup is the best of all methods. It will require a little experimentation on your part, but once you get the desired setup, it should perform very well.

Here is a paper test cone you can make to test the focus and zoom of your lens(es).

We are compiling a database of SLR camera/lens combinations. We ask our users to report back with the best combination for their setup.
