当前，不少影友在添购摄影镜头时，不同程度地注意到前苏联产的各种品牌和各种规格的超广角镜头和长焦、超长焦镜头。其原因，一是大多数品牌的镜头成像质量相当好，有影友试用后认为可以与日产品牌镜头媲美；二是价格非常便宜，仅日产同规格镜头的１／５～１／１０甚至更低。 At present, many shadow friends in the purchase of photographic lens, to varying degrees, noted the various brands produced in the former Soviet Union and a variety of ultra-wide-angle lens and telephoto, super-telephoto lens. The reason, first, most of the brand’s lens imaging quality is quite good, there are shadow friends after trial that can be comparable with the Nissan brand lens; the second is the price is very cheap, only Nissan with the specifications of the lens 1/5 ~ 1/10 or even lower .
