我到而家都睇唔明支 Sonnar 85/2 鏡構造橫面圖:點解呢支鏡叫做 "Sonnar" 而唔係 "Planar"??
如果掩埋叫我睇,我實話佢係 Planar design
I study it long and hard, and I cannot see any Sonnar design in there. Its a Planar design alright .... shame on them to tarnish such a name
When the N-series first came out, there was a Makro-Planar 100/2.8 as shown on the brochure, but we end up with a Makro-Sonnar 100/2.8 as production model. So who knows, and maybe the final version is in fact a Planar.
In fact that was quite a different story. The first macro lens Kyocera put on N-series was a real Macro-Planar design (though it never released afterward) that was exactly the same using on C/Y series. After Kyocera studied the problems to make the MP autofocus (or other concerns as well), they turn out a whole new design Macro-Sonnar lens instead.
What I doubt is the Planar-look lens composition which is named "Sonnar" in this 85/2 case.
I do hope that this lens will name "Planar" at last.
