森养 24mm T1.5 VDSLR ED AS IF UMC II 镜头是一款为了实现全画幅感应而设计的高感光度广角视频镜头。
作为摄像镜头的特点森养 24mm T1.5 VDSLR ED AS IF UMC II 主要是针对专业级的电影、视频制作者,根据他们对于高感光度镜头以及样式的需求,而量身开发的。为了切合这个目的,跟焦镜头齿以及视频用光圈可以安静柔和的调焦、调光圈,且为了使用方便,焦点和光圈的调节数值制作在了镜头的侧面。森养 24mm T1.5 VDSLR ED AS IF UMC II 是根据T值的电影、视频摄像镜头。F值反映的是镜头直射光线100%通过的时间,而T值反映的是实际光通量,所以使用T值可以进行更加精确的拍摄。 手动对焦部分以镜头齿的方式制作,这与拍摄视频时使用的跟焦系统以及视频用光圈非常的相配。这样的特点使得更加柔和精密的操控成为可能,最终使得手动对焦在电影或视频的拍摄时,即使是在阴暗的环境下也可以与一般室内环境一样进行拍摄。
光学上的特点由12组13枚镜片构成,包括4个超级低分散镜头(ED)、两个玻璃非球面镜头(ASP),独创的超级多重镀膜技术(Ultra Multi Coating, UMC)来使重影和耀斑现象最小化。森养 24mm T1.5 II 的ED,因其从根本上抑制了光的乱反射,所以可以最小化由杂光产生的影响。强光效果部分中,光线看起来像蔓延一样的耀斑,以及逆光时,明亮和阴暗的分界线处出现多种颜色的重影现象,都可以通过低分散镜头来抑制。为了减少色像差并减少由折射率引起的鲜明度过低,森养 24mm T1.5 II使用了ASP。根据各部分的折射率向一处聚集的特殊加工, ASP减少曲面像差的镜片,可以鲜明的成像。森养 24mm T1.5 II 为了可以展现美观的背景虚化效果而进行了设计,即使在低T值、相对阴暗的环境下,也可以优秀的进行远距离、园林、风景、建筑摄影的全画幅作业。
结构上的特点森养 24mm T1.5 II 的外部很坚固,花瓣形状的遮光罩可以降低耀斑和重影现象。滤光镜尺寸为77mm。可以用在 Canon EF, Nikon F, Pentax K, Sony A, Canon M, Fujifilm X, Samsung NX. Sony E, MFT 等9余个品牌的相机机架上。
VDSLR装备构成镜片森养 24mm T1.5 VDSLR ED AS IF UMC II是构成VDSLR装备的8种镜头之一,即便更换镜头也可以保持相同的色感,特别是,因为8个镜头的调焦以及光圈环安装位置相同,在摄影中可以方便的更换镜头,从而使作业速度变得更快。
