Quote from the manual: "A cross-microprism focusing system consists of a Fresnel lens, made up of many concentric rings, with microprism center underneath the ground glass..>>>" So I guess the large ring must be part of the microprism system, and in this case a 'down-side' part? All manual cameras with microprisms have got this large ring, so I figure it's just part of it.
Someone else got any facts? Now I'm curious also. Ow, and about what is a nice manual cam... I love my KX and like my K2 (although the latter is not as nice as the KX), but if you don't need the microprism, a more modern MZ has got quite a bright viewfinder. All the best. Rod.
