[QUOTE="Renze de Vries, post: 3171178, member: 10024"] Discussions about the terminology we use in evaluating binoculars are important because our evaluations are necessarily subjective, and so we should be as clear and specific as possible. Here's an older thread where concepts for evaluation are discussed: [url]http://www.birdforum.net/showthread.php?t=218607[/url] This is what I suggested in post #22: [B]Object Performance[/B] Sharpness (retrieval of fine detail, resolution) Contrast Color representation [B]Field Performance[/B] Brightness Transparency Sweet spot True field of view Apparent field of view Depth of field 3D-effect Color tone (fidelity) Flare, ghosting Vignetting [B]Practical Performance[/B] Balance Focusing Eye comfort Weather performance [B]Overall Performance[/B] Presence Note that I don't make a clear distinction between sharpness and resolution. Of course there is a difference, as outlined above, but as we deal here with subjective observation and impressions the concept of sharpness seems more practical. Renze [/QUOTE]
