Sirui Treppiedi S--N carbonio 5 sezioni SN
Sirui',s S--N Carbon Fiber Tripod weighs 2.6 lb and yet can support up to 26.4 lb. The S--N has individual leg spreading capability for low angles or uneven terrain. Besides the standard center column a short center column is included which allows the tripod to get down to 7". One of the legs is removable to convert to a monopod. When folded, the tripod is 17.7" long, and only 1.6" thick. 8 Layers of Carbon Fiber for Superior Load CapacityThe use of 100% carbon fiber and 8 cross pattern layers makes Sirui tripods and monopods capable of supporting impressive load capacities, while providing a lightweight product. In addition to providing high strength and low weight, carbon fiber is also highly resistant to temperature changes, friction (no need for lubrication) and corrosion.Custom Anodized Surface TreatmentAll Sirui products undergo a special anodized surface treatment that makes any metal surfaces highly resistant to wear and increases durability and weather resistance. Anodizing is an environmentally safe electrochemical process. This also prepares the surface to provide better adhesion of colored finishes.Temperature Tolerance TestPhotographers often work in extreme environments, like blazing deserts or sub-zero mountaintops. It is vital that your equipment works under these conditions. That is why all of these products are "torture-tested" under conditions that far exceed what most people will ever experience: -F (-C).Certified Longevity Tests for Quality and ReliabilityTo confirm the quality and reliability of Sirui tripods (and dedication to details), an independent testing lab (SGS) subjected the leg angle lock spring mechanisms to exhaustive longevity tests. The test reports show that even after actuations, the springs continued to perform perfectly.Short Center ColumnAllows low angle shooting for unique perspectives and macro photography.Precision Leg TubesThe difference in diameter of leg tubes is only 3.0mm from tube to retracted tube. Thanks to precision manufacturing, the legs open and close easily, while the small diameter difference provides added leg stability.Half-turn Leg LocksTo lock the legs of Sirui tripods/monopods, twisting locks are utilized for maximum reliability and stability. Simply twist the rubber leg locks 1/2 turn and the legs will extend by themselves.Unique Locking SystemThe Sirui S-N series tripods have a unique leg position locking system that clicks in place when the tripod is opened. This guarantees that the tripod legs will be properly positioned -providing a rugged, stable support for your equipment. Simply open the tripod in the direction of the arrows until it clicks into place. When you',re done shooting, press the red unlock button and close the tripod flat.Non-Twist Center Column/LegsAll Sirui center columns and legs have keyed, grooved channels that prevent twisting, providing additional stability and safety for your photographic equipment.Converts to MonopodThe detachable leg lets you transform your tripod into a monopod, this reduces the amount of equipment you need to carry and makes your camera bag or backpack lighter.

Leffetto del sistema anti vibrazioni visibile anche nel mirino, cos che il fotografo pu rendersi conto dellavvenuta stabilizzazione e procedere ad una accurata messa a fuoco.Due lenti in vetro ottico a bassa dispersione FLD (F Low Dispersione) offrono gli stessi risultati di lenti alla fluorite, inoltre due elementi forgiati in vetro ottico e uno ibrido, asferici, correggono in modo ottimale qualsiasi aberrazione. Il rivestimento Super Multi Strato riduce il flare e le immagini fantasma. Lobiettivo offre un contrasto periferico migliorato e produce immagini molto definite e contrastate anche alle massime aperture.La grande qualit delle immagini assicurata a tutte le focali.Il motore ipersonico HSM incorporato provvede a una messa a fuoco AF veloce e silenziosa, in qualsiasi momento possibile la messa a fuoco manuale.La distanza minima di messa a fuoco dellobiettivo di 28cm a tutte le focali, mentre il rapporto dingrandimento massimo di 1:5. Il diaframma rotondo a sette lamelle consente piacevoli effetti di sfocato.Il sistema di messa a fuoco interna elimina la rotazione della lente frontale e permette allobiettivo di montare un paraluce a petali e il polarizzatore circolare. se montato su una fotocamera FF l',immagine apparir vignettata Sigmas new mm F2.8 EX DC OS HSM large-aperture standard zoom lens covers a focal length from 17mm wide angle and offers a large aperture of F2.8 throughout the entire zoom range, making it ideal for many types of photography especially portraiture and landscapes.

Sirui Treppiedi S--N carbonio 4 sezioni SN
Sirui',s S--N Carbon Fiber Tripod is a complete departure from the old days of "lugging around" a heavy metal tripod. To begin with, it only weighs 2.2 lb and yet can support up to 26.4 lb. The S--N is so versatile in its adjustments that it does about anything you can think of short of bending. It has individual leg spreading capability for low angles or uneven terrain. Besides the standard center column a short center column is included which allows the tripod to squat way down. And it reverses for even lower perspectives. The icing on the cake is a removable leg that converts to a monopod. And when the shoot is over the S--N won',t take up much space either. It folds flat to a mere 1.6" thick. 8 Layers of Carbon Fiber for Superior Load CapacitySirui is one of the few manufacturers who make their own carbon fiber leg tubes. The use of 100% carbon fiber and 8 cross pattern layers makes Sirui tripods and monopods capable of supporting impressive load capacities, while providing a lightweight product.
