Three views of nesting Blue Herons, supervisor, nest builder and comfortable in the nest. Although the magnification is high, the quality of images through the spotting scope are not on par with camera lenses. I removed chromatic aberration and sharpened considerably in PS.
Pat, I already had an 80mm Scope ('though not ED glass,) so it was minimal investment of $25 to purchase a "T" adapter which connects the scope to the Nikon body directly. Given good conditions, the images are remarkable, but in high contrast situations, against a bright sky, you will find pronounced colour fringing. Maybe somewhat less with an ED glass. I have become convinced that a digiscope combo will never give the same quality as a good camera lens. But it may be a worthwhile compromise to get those long shots. Whether you get vignetting depends on the magnification. I get a full frame image in the middle to high magnification range. There is no autofocus and it is hard to get focus bang-on - at least with my old eyes. Although, on the D200, metering will work. Good sharpness and colour contrast may well require impeccable technique and/or selection of an appropriate scene. I would be more encouraging if it did not cost so much. However, if you had other uses for a Field Scope, or were going to buy one anyways, then by all means mate it with your D200. Eb
Eb - I know that commenting on this older posting is a little late - but I am seriously considering purchase of a Nikon Field Scope III 80mm ED and the Nikon FLA-1 connector for the D200. When shooting through a scope is the iamge a circle? Did you find that shots are sharp and colorful? many thanks for your input.
