Until I found this H&Y REVORING ND + CPL 3-in-1 filter, which is a combination of adjustable ND filter + CPL polarizer + adjustable adapter ring integrated non-removable filters.
First of all, it is its interface design is very clever, it itself is by the expansion of the spring to lock, the filter will be rotated to the tightest state is very solid; need to disassemble on the overall filter counterclockwise rotation a few turns will automatically fall off, very convenient.
I have this 67-82mm size can cover almost all of my lens group, do not have to match each lens with a set of filters, not only saves the money to buy filters, but also saves time and effort, greatly improving the shooting efficiency.
This set of REVORING ND+CPL 3-in-1 filters can be used not only on its own with ND filter, but also can be used on its own with CPL polarizers, or in combination to eliminate reflections + long exposure scrims; and on its own with a black mist filter to soften highlights.
The adjustable nd of 1.5-10 stops is very silky smooth to operate, and you can also carry a magnetic black mist filter according to your shooting needs, and it's very easy to install with a single suck.
After the assembly of this set of filters, the measured shooting color difference is also within the acceptable range, and whether it is the control of highlights or softening effect, but also to achieve near-perfect, but also will not affect the shooting effect, you can take into account the shooting of videos, landscapes and portraits and so on.
Next, let's look at the REVORING ND + CPL 3-in-1 filter under the support of the effect is what kind of shooting out?
