A comprehensive filter for neutral density and polarization, this 6 to 9-stop, 49mm PolarPro Chroma Variable ND & Polarizer Filter 49mmleverages newly designed Chroma Glass to create a filter with two distinct, independently controlled elements for neutral density and polarization in a bi-rotational design. The new glass also increases the filter's color accuracy, only incurring the color variance that results from polarization.

The neutral density filter allows users to reduce exposure values to achieve various effects, while the polarizer reduces glare and reflections to give an image a sharp, clean look. In addition to the space-saving combination of these functions, PolarPro has also improved the tactile experience of using the filter, incorporating ball bearings at each stop to lock the VND setting into place. The filter also features 16 layers of anti-scratch, antireflective, and anti-fingerprint coatings.

A: Yes it works perfectly fine with me. You will need to buy two clamps to hold paper from rolling

Q: 3. The directions for the adapter say it has to be removed from the camera before I can change lenses. Why? It seems that it would be easier to leave the adapter on the camera and just change the lens attached to the adapter.

A: We recommend always following manufacturer's instructions, even when their reasoning might not be clear.

Q: 5. The drop-in polarizing comes with the polarizing filterbut do I have to buy a clear filter separately if I want to photograph without a polarizer? Or can I just remove the glass from the holder? Meaning I can't just take the whole thing out and have an open slot in the adapter, right?

A: You would have to purchase the clear drop in filter and use in place of the polarizer. Click the link below to view; https://bhpho.to/2YSbEQ8

Q: 6. Can I change lenses on the adapter without removing the adapter from the camera? I know the directions say to remove the adapter from the camera first, but I would like to know why.

A: Yes, Canon Drop-In Filter Mount Adapter EF-EOS R with Circular Polarizer Filter has a lens release switch to remove or interchange lens on the Canon full-frame mirrorless cameras. Canon recommends removing the lens and adaptor in the first step as a safety precaution. Also is assume that you are removing the lens to put your camera away instead of switching lenses in the field. There is no harm caused to the camera or adaptor if you keep the adaptor on the camera and remove just the lens.

Q: 7. Is this a good back drop support for photo booths that require either paper, cloth, or any material back drop? Also how do you attach the seamless paper roll to it?

A: Yes. This will accommodate both paper and material. The paper has a hollow core. Run the cross rod through it. Buy some pony clamps to prevent the paper from unraveling. A variety of clamps are in the accessory list for this background support.

Q: 8. I got this system along with a 10'x12 muslin background. What do you use to hold the muslim on the sides to make it seamles? A standard clip does not seem to work because there is a lot of space between the side bars and the muslim sides

A: We use several clamps like you can buy at Lowes or Home Depot. Youll need a few on each side. If there is too much gap youll need to get a shorter cross support beam . They make some that are adjustable. I would also recommend gaffers tape on the floor to tape the edges. Hope this helps.

Q: 9. I noticed there are two variants of this for the Sony 12-24. One has a landscape polarizer for $499 and the other has a standard polarizer for $279 I think. Is it really worth the extra for the 25% greater saturation? Isn’t this something you can add in post?

A: I understand the additional cost for the landscape polarizer and is there value in this one over the standard polarizer. The answer is yes, it is definitely worth the additional cost for the "landscape" polarizer. Could this be done in post, perhaps, but are you will to take that chance with the investment that you have made so far, and shooting in a location that you might never return to. When you use this landscape polarizer, you achieve a more natural saturated look. Always try to get it right in the camera and don't rely on possibly "fixing" it in post.

Q: 10. Can replacement crossbar sections be purchased separately?

A: Sorry, I don't know. I only purchased the kit that was on the BH website. It is a great product, though. Really easy to use.
