Leica M Summilux 50mm/1.4 on Hexanon 52mm/1.8 helicoid

Not a few photographer might feel some inconvenience to make use of old range-finder camera lens on recent digital mirror-less format, because of lack of close-up capability. For example, most of Leica M lenses were so made to focus up in the range of infinity and 1 m, the nearest position for the standard lenses are not enough especially when used on a recent designed digital camera body. Ordinary 50 mm lenses produced for SLR in silver salt period have 45 cm close up capability, there exists some big difference between them for usual conveniences. The same opinion could be declared on Leica M Summilux 50 mm/1.4 second generation. It is true that it could be used on SONY E-mount body without any Physical problem except the close-up capability. On the other hand, the possibility to brought out side is reduced because of the dictated problem.

I caught my eyes  on the fact that the lens module including iris construction and helicoid mechanical moving part can be separated, then, what will happen if the module could be put in an another helicoid mechanism with close up possibility?  Just conveniently could I obtain Konica 52 mm/1.8 SLR lens at only 1 yen from Yahoo auction, my idea should be realistic at all so I determined. The helicoid extension of Konica 52 mm is 45 cm and Summilux lens module is acceptable diameter with the least modification on Hexanon lens case.

I must declare here why I insist on Leica M Summilux 50 mm/1.4, it is the extraordinary correction of spherical aberration, S shape curve correction is done between 1.4 and 2.0, this method has not be came across with in the field, no other one has such a way like this lens. Of course Summicron has outstanding character in any performances, sharpness and resolution, but if the title comes to "lens taste", my ranking is changed immediately, Summilux 50 mm/1.4 is the second to none, especially on the resolution of atmosphere at the moment. According to my long lasting distinction on that, I came to the conclusion to proceed to operate on this case as a matter of fact.

Because my Leica M Summilux 50mm /1.4 has acquired the capability of close-up shooting 45 cm at the minimum distance, I will make it a rule to bring out whenever I do it keeping it at the corner of my C-bag.
