Attaching Opticals To Your Camera Lens For

High Magnification Imaging Using Monoculars, Binoculars and Spotting Scopes

It can be shown that if a TTL (thru the lens viewing) camera lens is held up close to the eyepiece of most any optical device, such as a monocular, binocular, or spotting scope, one can see the subject in the eyepiece thru the view finder of the camera. You can also take a picture of what you see in the view finder by holding the camera close to the eye piece. This however becomes quite difficult when you have to hold the camera and the optical device at the same time while trying to focus and click the shutter.

The Lens To Eyepiece Connection

If you can hold your camera up to the eyepiece and take images this way, how can one hold the eyepiece of an optical device so that it will become an integral part of the camera lens?

"Three criteria are important. First, the method must be safe for both the optics of the camera and the microscope. If there is any possibility of scratching these, the adapter must prevent this unhappy event. Second, the method must be stable to prevent camera shake. Third, the adapter should block extraneous light from entering the camera from the gap between the lens and eyepiece"

Preferred Camera Type

Until the digital camera manufactures can design a hood for the camera monitor or a monitor that one can use to view subjects in daylight...the camera of choice has to be one that you can compose your images by viewing thru the lens.

There are a growing number of camera accessory suppliers on the Internet that are starting to help resolve this problem by designing hoods that attach to the tripod threads in the bottom of the camera or are held on by velcro strips attached to the sides of the monitor.
