Does an Impression V Filter have to be attached to the back of a lens in a specific orientation?
Impression V 复古滤镜是否必须以特定的方向安装在镜头的背面？
The rear magnetic filter adapter has 12 magnets which allows for 12 different mounting positions of the filter. However, since all Impression V Filters are rotationally symmetrical, the filters will produce the same effect, regardless of which orientation you choose to attach the filter to the lens. The witness marks on the filter and the mount of the lens are just a reference in case you intentionally want to alter the filter.
Signature镜头后置的磁性滤镜环上有12个磁性触点，使得滤镜可以从12个不同的方向上安装。然而，由于所有的Impression V复古滤镜都是旋转对称的，所以无论您选择从哪个方向将滤镜安装到镜头后方，滤镜都会有相同的效果。另外，如果您还想需要安装参考，可以将滤镜上的标记与镜头上的标记结合起来，将滤镜的方向定在12个 档位中的一个。
