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.
Please note: We use a shipping tool that selects the shortest transit time from 3 carriers, FedEx, UPS, and USPS. Most small items go USPS Priority, while most large items go FedEx. The listing only shows one carrier, UPS, as it does not let us reflect the above policy, but again, it may go any of the three carriers listed above. If you have a restriction on your address, and would like a specific shipping as a result, you must contact us PRIOR TO ORDERING! We will do our best to accommodate shipping requests, although we cannot always do so. If you place the order and then contact us after the fact, it is likely our automated system will process your shipment using the shipping tool, and once shipped we CANNOT make any changes. This includes rerouting, changing signature requirements or having packages held.
Please use the "Contact seller" link located in the above right "Seller information" section, and we'll get back to you as quickly as we can. Please do not ask questions after placing your order that would impact your order decision, as once an order has cleared eBay's waiting period, it will be automatically processed by our system.
