| This system employs a "collimate shooting
method," which means that the digital camera is set just behind
the Fieldscope's eyepiece to capture the observed image. In this
method, the shooting focal length is a product of the Fieldscope's
magnification and the digital camera's 35mm format equivalent focal
length, thereby allowing super-telephoto (close-up) shooting. There
is a variety of brackets and attachments available to connect a Nikon
Fieldscope eyepiece to a digital camera, making it a breeze to take
super-telephoto shots. |
| |
 |
 You
can take close-up pictures from locations even more distant than
is possible with regular telephoto shooting using an SLR camera.
Amazingly enough, super-telephoto shooting with a composite focal
length of over 3000mm is possible, allowing you to easily capture
close-up images of timid birds, animals and other difficult-to-approach
subjects. |

We recommend that you use a wide-angle setting
for super-telephoto shooting when combining a digital compact camera
with the Fieldscope.
Also, because it might be difficult to obtain focus when using a
digital compact camera's AF function, we recommend that you take
a series of pictures of the same subject. |

*The picture angle of 35mm-format SLR cameras
differs from that of digital SLR cameras due to the difference in
the size of captured images. The 35mm equivalent focal length is
1.5x (2x with Nikon D2x High Speed Crop) of the focal length of the
lens used. |

Digiscoping allows you to capture a full-frame
image of a distant bird. Super-telephoto shooting can also be easily
performed, capturing detailed images as fine as a single blade of a bird's
feather. |
 |
You are
ready to start digiscoping. |
| |
• |
The total weight
of the system is approx. 3 kg, freeing you to go into the field
without any concerns over weight. |
| |
• |
The total cost of the equipment
is approximately one-third the cost of a complete super-telephoto
system with an SLR camera. |
| |
|
Using the
Fieldscope as a telephoto lens for super-telephoto shooting in
combination with a digital camera |
| |
• |
You can take as many pictures
as you want without worrying about film or developing costs. |
| |
• |
You can check each image immediately
after it is captured and save only those that are successful. |
| |
|
Easy operation |
| |
|
Adjust the focus ring on the
Fieldscope while monitoring the subject on the LCD panel, then
use your digital camera's AF function to focus the image. These
functions are so easy that even a beginner would have no trouble.
But be careful not to generate vignetting or vibrations during
the image-capturing process. |
