再公开6支RF镜头专利 佳能已成专利狂魔

在日系相机、镜头品牌,佳能是专利数量的最多的厂商,在EOS R发布后,更是隔三岔五公布新镜头专利,近日又双叒叕公开了RF镜头专利,数量多达6支。

佳能此次公开的RF镜头全是超广变焦镜头,分别是RF 15-35mm f/2.8L、RF 17-70mm f/3.5-5.6、RF 15-35mm f/4L、RF 16-35 f/4L和RF 14-40mm f/4L。其中RF 15-35mm f/2.8L应是早前公开展示RF 15-35mm f/2.8L镜头样品的对应专利;RF 17-70mm f/3.5-5.6是一支全新焦段的超广变焦镜头,横跨超广、广角、标头、中焦四个焦段,非常吓人;RF 15-35mm f/4L、RF 16-35 f/4L、RF 14-40mm f/4L和RF 16-40mm f/4L四支镜头规格非常接近,相信佳能会从中挑选一支作为RF卡口的小三元镜头。

除了六支RF镜头专利,佳能近日还公开了11支EF镜头专利,分别是EF 16mm f/1.4、EF 20mm f/1.4、EF 14mm f/1.8、EF 16mm f/1.8、EF 17mm f/1.8、EF 18mm f/1.8、EF 18mm f/1.4、EF 20mm f/1.4、EF 14mm f/1.8、EF 22mm f/1.2、EF 24mm f/1.2,全是超广定焦。其中EF 20mm f/1.4很可能是佳能电影镜头CN-E20mm T1.5 FP X、CN-E20mm T1.5 L F对应专利,估计这批专利是这对电影市场的,不会有相机镜头。

在EOS R发布后,佳能精力完全转移到RF卡口上,从那天起到今天都没有发布过一支EF卡口镜头。可RF系统真正的短板在于机身,EOS R完全没法与索尼A7M3、尼康Z6抗衡,靠镜头海是无法弥补机身上的差距,更不能靠镜头专利刷存在感、吊人胃口。

    大众消费市场都快没人买相机买镜头了,爱摄影的叔叔都让我帮忙看10X变焦的手机了,相机厂挤牙膏已经毫无意义了,大法相机买的这么好,部门都照样拆分跟手机合并去了,大势所趋,消费电子领域佳还是能赶紧找个手机大厂合作吧
