The Olympus 15mm f/8.0 Body Cap Lensthat we first saw back at Photokina is now readily available for $49. This is a great accessory for micro four thirds shooters, and at a terrific price.

About the size of an Oreo cookie, the BCL is perfect for your backup camera because it keeps it ultra compact so you can fit it just about anywhere. If you need to take a quick shot, move the lever on the lens to the "dot position" and shoot. The image quality is remarkably good. It even has a macro mode by moving the lever all the way to the right.

When you're done shooting, slide the lever all the way to the left so it lines up with the orange marker. That slides the lens cover in place to protect the optics.

My big tip for shooting with this lens is to be sure to line up the lever with the white dot when in regular shooting mode. You'll feel a click-stop there. By doing so, your general photography shots will be in focus. If you're just a bit off in the alignment, they will be out of focus.

I really like this accessory. I doubt that I'll be using my regular body caps again. They just seem so one-dimensional compared the the BCL.
