This 58mm Magnetic Quick-Swap Neutral Density 1.2 Filter from Freewell is an ND filter with a 16x filter factor that provides a 4-stop exposure reduction. The filter's 1.2 density darkens the entire image area without affecting the image's coloration, allowing the photograph to be made with a wider aperture or slower shutter speed than is usually required. Widening the aperture allows for finer control over depth-of-field to help isolate the image subject or increase bokeh. Slowing the exposure time increases blur and conveys movement more easily.

Each surface of the filter is multicoated to help eliminate internal ghosting and reflections. In addition, it features a resistance coating to repel oil, dust, and scratches, offering greater protection to the filter when working on location in harsh environments. The coatings are also hydrophobic, resulting in an improved beading effect when in contact with water or oil for easier cleaning and maintenance. The aluminum filter ring also includes 58mm front threads, permitting the use of screw-on filters with 58mm rear threads.

This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.

Q: 1. With the 77mm magnetic adapter ring attached to my Sony 24-100mm lens (also 77mm thread), can the lens hood still be used? And same question for the 100-400 mm lens.

A: Yes, it is possible to use the Sony lens hood when using the Kase 77mm Wolverine Magnetic Professional Neutral Density Filter Kit II on your lens.

Q: 2. Will these filters vignette with ultra wide lens. In my case Fuji GF 20-35mm f4.0

A: The Kase 82mm Wolverine Magnetic Professional Neutral Density Filter Kit II would offer thinner rings, so the likelihood that they will vignette with your Fujifilm GF 20-35mm f/4 is minimal.

Q: 3. I have the Fuji GFX 100 S. Do these Wolverine case magnetic filters resolve 100 megapixels?

Q: 5. Hi everyone, My most used lenses are 82mm, however, I do have 200-600 that I have used filters on in the past. That is 95mm. I am not sure if its better to get the 95mm set with an 82mm step up ring - or just get the 82mm set. Not sure how often I will use filters on the 95mm lens..(though its nice to have) - I currently use Nisi square filter - and they do fit the 95mm lens - but Id rather not have to pack two filter systems. which one would you buy? thanks

A: We would recommend getting the Kase 95mm Wolverine Magnetic Professional Neutral Density Filter Kit II then the Kase Magnetic Step-Up Ring for Wolverine Magnetic Filters (82 to 95mm), BH # KAKWMSP8295. https://bhpho.to/3LOH7g7

Q: 6. Has anyone used this system with a Canon RF 15-35? If so do you get vignetting at 15mm when stacking the ND and CPL filters?

A: By adapting the 95mm filters to an 82mm filter size, there will be no vignetting when stacking 3 filters.

Q: 7. Does a single 82mm filter create vignetting for Sony 16-35 GM at 16mm?

A: At 16mm the Kase 82mm Wolverine Magnetic Professional Neutral Density Filter Kit II can produce a small amount of vignette. Some say they do not notice most of the time.

Q: 8. Will these cause vignetting on the Sony 24-70 f/2.8 GM II when stacked? I probably wouldn't use more than 2 stacked at a time (the CPL + a single ND).

A: You can only attach one filter at the time on Sony 24-70 f/2.8 GM II lens. stacking 2 filters will vignette if you are shooting on a 24mm wide angle lens range with a full frame camera. I will recommend getting a step up ring 82-95mm to connect Kase 95mm Wolverine Magnetic Professional Neutral Density Filter Kit II instead of the 82mm kit if you are planning on multi stacking the filters.

Q: 9. Will this work with step Will this work with step rings, 72–77, 62–77 as example?
