Tips for choosing a Fieldscope

The ED series of Nikon Fieldscopes use ED (extra-low dispersion) glass in their objective lenses, which compensates for chromatic aberration and produces a sharp field of view. They have superlative brightness and resolving power. They utilize the same focusing method as do telephoto lenses for SLR cameras. You can focus from the closest focusing distance to infinity with just a 3/4 turn of the focusing ring, which is extremely easy to operate, enabling you to focus in an instant.*1

Choosing by objective lens diameter

Diameter Brightness Depth of field Size Weight
ED82 (82mm) Very bright Shallow Large Heavy
EDIII (60mm) Bright
ED50 (50mm) Moderately bright Deep Small Light

The ED82, with its large 82 mm objective lens diameter, has a shallow depth of field, meaning that the area that is in focus is quite narrow. However, it offers clear and sharp images. On the other hand, the EDIII/III (60 mm) and ED50 (50 mm) have a greater depth of field so the area that is in focus is larger, which raises the chance of getting a good shot. Please choose the scope best suited to your photographic objectives.

ED82

ED82: Only the area around the couple in the middle is in focus, while the couples in the foreground and background are completely out of focus.
 ED III
ED3
EDIII: Compared with the ED82, the couples in foreground and background and the surrounding greenery are more clearly in focus.

Choosing by lens type
