自2012年底推出新35mm f/1.4镜头之后,适马镜头在产品外观、做工质量、镜头成像方面都有了一些进步,在2013年,适马镜头的发布速度也在加快。这次我们评测的适马30mm f/1.4 DC HSM是一只APS-C专用镜头,适用于佳能、尼康、适马的单反机身,这只镜头在适马SD1及尼康DX机身上的等效焦距是45mm,在佳能机身上的等效焦距为48mm,因为等效焦距与全画幅的50mn标准镜头焦距相当,所以镜头的视角也与人眼视角类似。适马的这只新30mm f/1.4与35mm f/1.4 DG,18-35mm f/1.8DC同属适马最新的A系列镜头,所以在镜身材料、外观设计、操作手感方面都与适马同系列镜头相差不大。虽然现在全画幅单反相机已经比较普及了,入
