SIGMA的中文音译是“适马”,各大色友及论坛上常谐称之为“死马”。 SIGMA主要产品是各类镜头, 其生产的镜头通常被冠以“副厂”镜头,其实它很早就生产了自己的SLR,比如SA- 1(PK 口),AF(自动对焦)时代也生产了 SA-300/SA-7/SA-9这样的使用自有的 SA卡口的AF SLR,也生产了SD—9/SD— 10 DSLR,所以很难说它是原厂还是副厂,对使用SA卡口镜头的用户而富,它的镜头是原厂;对于其他卡口的用户而育,它是副厂。
SIGMA Chinese transliteration is “Sigma”, the major color friends and forums often called “dead horse.” The main products of SIGMA are all kinds of lenses. The lenses they produce are usually labeled as “deputy factory” lenses. In fact, SLMA has long been producing its own SLRs such as SA-1 (PK port) and AF (auto-focus) The AF SLR using its own SA bayonet such as SA-300 / SA-7 / SA-9 also produced the SD-9 / SD-10 DSLR, so it is hard to say whether it is original or secondary. SA bayonet lens users and rich, its lens is the original; for other bayonet users and education, it is a deputy factory.
