MakroPlasmat 35ｍｍF2.7 　 It is the only mileometer synchronization wide-angle lens of LeicaScrew(L39) of the Mayer Co. Why did the Mayer Co. choose this lens as 35mm wide-angle lens?、Wasn't there Kinoplas　mat in 35mm wide-angle lens of LeicaScrew(L39)?　（KinoPlasmat exists as 35mm wide-angle lens the lens for the movie. 　The lens remodeled as LeicaScrew(L39) is sometimes seen in the market. 　 However, formal LeicaScrew(L39) doesn't exist.　It is said that one has a formal LeicaScrew(L39) lens, and it might be distance system non-synchronization, and be the lens that the shop of the Leica Co. made a Leica mount. 　It is not certain.　LeicaScrew(L39) Kinoplasmat35mm wide-angle lens that I had confirmed remodeled Kinopl　asmat for the movie. 　Moreover, 35mm wide angle is not recorded in the catalog of pure LeicaScrew(L39) of the Meyer company.）MakroPlasmat was chosen as the only LeicaScrew(L39) 35mm Meyer Co. wide-angle lens. 　I guess that the reason why Makroplasmat is chosen is more excellent than rival's function. 　It was brightness (F value) and the best value was F2.8 compared with 35mm wide-angle lens of the other companies. 　The best rival lens is Biogon of Ziess.　Biogon was very excellent in the contrast and the Sharp function. 　Leica wide-angle lens at that time was dark. (ELMAR35mm､HEKTOR28mm)　Because there were neither the other companies nor a good wide-angle lens.　However, it is not possible to fight in Biogon35mm. (contrast and Sharp function)　The Meyer Co. did not fight in the same function. As for the Makroplasmat lens, the tone function of the resolution and the color was excellent.It fought by the function

The popularity of MakroPlasmat is also high. It was adopted for various cameras.　 It might be a reason why the Makroplasmat lens (Leica screw (L39)) was chosen to be 35mm wide-angle lens.　　Then, why was not lens (Kinoplasmat) that was brighter than makroPlasmat selected as a wide-angle lens (Leica screw (L39))?　　It is dominant in the point said that the lens is bright. However, because the content of the selection was a wide-angle lens, KinoPlasmat had the problem of the flow of quantities of light in the surrounding in respect in the angle of field and a peripheral image etc. Therefore, it might have been judged that the commercialization of the wide-angle lens was difficult.　　However,Kinoplasmat is marketed as a high-speed lens of 50mm(Leica Screw(L39)) or more.　　MakroPlasmat might have been produced as Leica Screw(L39) and ContaxCX Baiyonet because other lenses were not in the Mayer Co. as a wide-angle lens.　　Leica Screw(L39) of MkroPlasmat has 35mm, 50mm, and 105mm.　　　　　　75mm lens might not have been made so that there were PrimoPlan and Kinoplasmat.　 There are 75mm in EXAKTA. 　35mm lens has ContaxCX Baiyonet.　　The synchronization cam comes off easily from this. The mileometer non-synchronization. The mileometer non-synchronization lens seems for this 　　　When the Makroplasmat35mm lens is seen, the shape of the body is a mushroom type lens a little.　　There are two kinds about brass body and nickel body.　　Shape is considerably good.　　When this lens was seen for the first time, I wanted it.　　It is too a lens with the impact.　 In this lens (For the one in this age),. the high definition image is wonderful and. Moreover, the tone is rich.　 There is an appearance of solidity, too.
