<p><strong>Teleconverters: TC-1401 and TC2001</strong></p>
<p>The teleconverters TC-1401 and TC2001 are developed as dedicated attachments for Sigma Global Vision lenses. By mounting it in between a telephoto lens and a camera, the TC-1401 and TC-2001 will magnify a lens’ focal length by 1.4 and 2 times, respectively. Both models now incorporate Special Low Dispersion (SLD) glass elements, the TC-1401 with 1 and the TC2001 with 2 SLD elements, which offer excellent aberration correction and maintain the exceptional image quality of the original lens. The TC-1401 will be sold for the street price of $349, and the TC2001 will be sold for $399. Availability is still yet to be announced for both teleconverters.</p>
<p>The teleconverters come packed with additional special features – its power distribution is designed for Sigma lenses of large diameter. Without affecting the lens performance, these options offer stable image quality through the zoom at every focal length and on the corners of the frame. Additionally, the tele converters are designed for high durability – being both dust and splash-proof. These new teleconverters are capable of shooting effective AF at F8, if the camera can do so.</p>
<p><strong>Filter lineups: WR Protector, Protector, WR UV Filter, WR Circular PL Filter</strong></p>
<p>With the new Global Vision lens filters, Sigma will now offer 13 filter size options in four new lineups. These filters offer several new features that enable photographers to maximize the optical performance of Sigma’s lenses in various conditions. The filters will be available for purchase in October.</p>
<p>These filters have a new design that suits the high optical performance of all new Global Vision products to prevent vignetting or the decrease in peripheral light quantities especially when the thinner wide type filters are used with Sigma lenses. By incorporating Sigma’s Super Multi-Layer Coating, the filter reduces flare and hosting; black rimmed glass eliminates unnecessary internal reflections, and provides high performance for both digital cameras and film cameras. In addition, to ensure versatility, Sigma’s WR filters feature excellent water and oil repellent as well as an antistatic function, and the two types of “Protector” can protect the lens surface effectively.</p>
<p><strong>The four line ups include:</strong></p>
<ul>
<li>WR Protector (Water-repellent, antistatic type) and Protector (normal type): The protector is developed to protect the lens surface from dirt and dust as well as scratches. It is an ideal filter for regular use as it is completely colorless so it does not affect color reproduction.</li>
<li>WR UV Filter (UV water-repellent, antistatic type): UV filter prevents the bluish tone that generates by absorbing ultraviolet rays. It is effective in most situations, such as landscape, portrait and general photography on a sunny day.</li>
<li>WR Circular PL Filter (PL water-repellent, antistatic type): Circular PL filter removes the reflection of water surface and glass windows, and increases the contrast in landscape photography.</li>
</ul>
