Swarovski, through skilful design intent and application, have offered us their interpretation of a 'flatter field'. Leica, through skilful design intent and application, has chosen a somewhat different path. Henry, regarding this topic, you will note that neither Swarovski nor Leica use hard scientific data to either prove their case, denounce their competitors, nor to convince us into purchasing their product. That is because, regarding an image as witnessed through binoculars - there is no applicable hard scientific data to neatly plot, measure and explain away a 'flat field' or 'field curvature'. When anybody speaks of these phenomena in relation to an image viewed through binoculars, they themselves (yourself included) have entered the shifting sands of the descriptive and subjective world. I see nothing wrong with that, but let it be known for what it is.Rathaus</blockquote>
