K&F Concept 67mm Variable Fader ND2-ND32 ND and CPL Circular Filter No X Spot ND

Description

【ND & CPL filter 2 in 1】One filter has the ND and CPL filter features, it can not only reduce the amount of light entering the lens but also darken skies, manage reflections at the same time.
【No “X” cross on images】Say goodbye to the "X" cross on images, K&F utilize cutting edge technology you're going to say goodbye to this common issue with wide angle lenses and variable ND filters.
【Material】Made by completed professional optical glasses, Multi-layer coating, only allows 0.7% light transmittance and waterproof, scratch-resistant, which could protect your valued lens.
【Filter Frames】Filter Frames made by aluminum alloy, the serrated design of the edge of the frame makes it easy to install. There is 5 mark from Min to ND32 one frame, It is convenient for you to sure the ND filter stops.
【Note】This Filter is compatible with all 67mm lenses. Please verify your camera's lens thread size(usually marked somewhere on the lens barrel or printed underneath the lens cap) before ordering. The number is always preceded by a "ø" (diameter) symbol.
If the dimming is not enough during the use of the CPL filter, we will choose to add an ND mirror to achieve the desired shooting effect, but under such effect, it can not get the full wide angle. There is no vignetting, it is really a headache. The so-called vignetting and super wide angle can not have both, in general, this state can only abandon the super wide angle without the photo lacking a strong impact, and now we have achieved integration.
Filter lens:
1. Both sides are coated with waterproof and scratch-resistant green film, the coating is green under the illumination of the light;
2. Top optical glass, double-sided multi-layer enhanced coating, can effectively reduce the filter Surface reflection, the transmittance can reach 99.6%;
3. Both sides are polished and polished, which balances the light penetration trajectory to ensure the image quality is not damaged.
4. As a filter, paying attention to the protective performance, the most important protective performance of the lens is that it has double-sided waterproof performance. The surface of the lens has been specially treated with water. If water is accidentally poured onto the filter, the water will still remain solidified. Spread out, it is easier to carry and clean.
Filter frame
1. The outer frame of the filter is made of aluminum alloy and the color is black.
2. The serrated design of the edge of the frame makes it easy to install the filter. The rotation of the rotating ring is even and the hand feel is fine. The CPL and ND lens are assembled on the design, and the function of CPL is realized on one finished product.
3. The periphery of the product frame also has five scale values ​​from Min to ND32, and the black outer frame is matched with The white characters are very eye-catching. It is worth mentioning that this product has a frame self-locking technology. When rotating to the Min end or ND32, the frame is automatically locked for easy dimming positioning. Avoid the phenomenon of black cross;
4. When fixes the ND value, the effect of CPL is realized when the sawtooth frame is rotated.
