"Long bow clip" the filter clamp using transverse composite spring (spring metal + plastic shrapnel) clamping way Features are as follows: (1) filter installed smooth, almost no wear to filters; (2) the filter adjustment, lightweight and convenient, feel good, tart without any resistance; (3) long bow clips at the time of installation, adjustment and replacement without having to use any tools; (4) long bow clips each piece pin and hole, the combination installation fast and accurate; (5) the clips on the filter without any shelter, you make 100mm wide width achieved 100mm of the lens so 85mm wide mirrorUse width achieved 85mm so 150mm wide width achieved 150mm of the lens, or 100% ensure that filters the whole siteAvailable limit reduced vignetting; (6) original GR100, GR100S, GR150S, GR150, GR150P bracket, bracket upgrade kits only need to configure a f, lLevel for GR100F, GR100SF, GR150SF, GR150F, GR150PF full filter support; (7) the long bow clips has been the national utility model patent, the national invention patent under review.   Tips:     &Nbsp;  filter support material, and friends seem to be more concerned about. Special is the result of some businesses and "experts", and it seems there's only metalMaterial is the best.     Actually really like this? Application of metal, has a history of thousands of years, in the last century, or even the last century reached a peak. NowIn, along with the rapid development of science and technology of materials, metal a unique phenomenon had become academic. In many ways, non-metallic materialsIts unique, unmatched features, and has completely replaced the metal. For example, Boeing 777 aircraft non-metallic materials-5%-the latest Boeing787 Dreamliner, non-metallic materials already accounted for weight 50%, volume of 80%.     But I no special preference for metallic and non-metallic materials, feeling fit is the best to use, for example, my bracket is high strengthPlastic, rings are aluminum alloy, screws rivets are brass, spring is manganese steel, Chuck is a combination of brass and nylon material, and so on. AsBody material, personally think that aluminum has the following disadvantages:     (1) scaffold belongs to thin-walled cavity-type parts, easy deformation. And no elasticity and strength of aluminum alloy, but by squeezing or knocking, it will lead toRecovery of deformation, light effects, may not be used;     (2) aluminum Black oxide layers are very thin, use will inevitably bump, can cause multiple white;     (3) aluminum alloy surface is smooth, friction small, very easy to accidentally drop, cause damage to the Stent and filter;     (4) engineering plastics can be corrosion of acid, alkali, salt, aluminum can not do;     (5) metals in cold areas, is very inconvenient to use. Why outsourcing leather grip, why the lens zoom or adjust ring in almost no goldGenus? Opportunities for these areas at the time of photography and touching up. In harsh climatic conditions, especially cold conditions should be avoidedHands come into contact with metal, this is the basic principle of manual product design!     (6) with the progress of modern mould manufacture technology, precision plastic parts have significantly improved, and widely used language field of precision instruments,Foot supports precision to spare. And because it is machined out of aluminum alloy, consistency is poor, unstable and tends to match and difficult.       Aluminum alloy also has a lot of advantages, but most of them are for the manufacturer:     (1) small, not to cast a lot of mold;     (2), the design requirements are not high, design flaws, you can quickly change, will not be scrapped tooling, less risk;     (3) updates faster, is machined out of aluminum alloy, can change at any time change or re-enter the mold. And can quickly escalate into second generation, The third generation, so consumers will be constantly updated, pays.
