H&Y FAQs

Q. Can I use other branded filters such as Nisi, LEE, Formatt Hitech & Haida with the H&Y magnetic filter frame?

Yes. So long as your glass filters are 2mm thick and measure either 100x100mm or 150x100mm and do not have an existing frame, they will work with MF01 and MF02 H&Y magnetic frames

Q. Can I secure the filters in place when they are magnetically attached? 

Yes. You can secure the first filter after magnetically being applied to the holder using a small screw on the side of the frame. 

Q. Can I stack filters?

Yes. Because of the magnetic frame, you can stack multiple filters and adjust the height position for your desired effect. Be careful not to stack too many in case the weight becomes too much and they begin to come away from holder. 

Q. Is there any risk of light leak? 

No. The K-series holder comes with hardened foam already fixed to the holder preventing light leaks, especially useful when shooting long exposure pictures. When you stack the K-Series filters, the frame itself also prevents light leaks.

Q. Can I use the 95mm drop in filter as a screw in filter too? 

No. All of the 95mm drop in filters come in a fixed frame specifically designed to work with the K-Series holder. 

Q. Can I remove the magnetic frame easily when not using it anymore?

Yes. It’s very easy to remove as well as re-attach when you need to use it again. 

Q. How much f-stop reduction will I get with an ND32?

Take a look at the following chart which outlines all of the expected f-stop reductions you will achieve with H&Y Neutral Density filters

REVORING FAQ

Q. Will spare parts be supplied by H&Y?

The RevoRing is currently sealed, which means that you cannot open the system up. So, no spare parts will be supplied.

Q. What other accessories should I consider with this product

The RevoRing range allows for 52mm, 67mm, 82mm and 95mm round filters. H&Y have a selection of round filters which will be listed on the website and available in our post campaign survey.

Q. Will the RevoRing Products be made for other fixed filters later?

We have created the RevoRing to cover lens threads between 37mm to 95mm, and the filters used on the various sizes are popular sized round filters 52mm, 67mm, 82mm and 95mm.

Q. Will H&Y make a magnetic round filter holder for this RevoRing, and can I use other magnetic filters on it?

H&Y are considering launching a RevoRing Round Magnetic Filter Holder, and we will be looking to make it compatible with other brands of magnetic round filters. We would recommend however using H&Y’s products on H&Y filter holders. 

Q. Is the RevoRing compatible with all other filter manufacturers?

Yes, it will fit other round filter brands. 

Q. What is the warranty period and what will this warranty cover?

H&Y warrants that the Product will be free from manufacturing defects (Latent Defects), when properly cared for under normal use, for a period of 12 months from the date of receipt by the customer.

Q. Will you have other sizes?

We have launched the RevoRing for use with lenses from 37mm to 95mm. This range should be fully compatible with all lenses in the market. So, there is no plan for further new sizes at present. If a new size requirement becomes required, then we will develop a new size RevoRing as well.

Q. How durable is the anodizing?

Anodic oxidation is the best dyeing process to ensure that the color will be maintained. “Anodic oxidation is an electrochemical method for the production of an oxide film on a metallic substrate. It removes electrons from a substance and oxidizes the anode. Anodic oxidation increases corrosion resistance and wear resistance, and provides better adhesion for paint primers and glues than does bare metal.”

Q. Can it fit on lenses with built-in hoods?

No, it’s designed to be attached on top of the lens, so the built-in hood would need to be removed.

Q. How do I attach the RevoRing onto the lens? Is there a special way?

We will provide an instructional video when we ship the product and make it available on the website. We recommend that you turn the RevoRing and release the Ring once it is in place on the lens, by manually releasing the ring (do not let it spring back), and then giving the RevoRing a short turn to ensure that it is engaged on the threads of the Lens.

Q. What happens if I cannot use two hands to remove the RevoRing?

You can apply the RevoRing onto the Lens with one hand! You do this by rotating the RevoRing to compress the diaphragm, then using one hand to place it onto the lens, and slowly release the ring so it engages with the lens threads. When removing it with one hand, you can simply turn the RevoRing anti-clockwise a few times and it will disengage from the lens threads.

Q. How long does the Rotation function on the RevoRing last? **

With careful use of the RevoRing, including protecting it from dirt and water, the product should operate as intended. If there are any issues within the warranty period, you will be able to return the RevoRing for repair. 

Q. What happens if the Rotation function on the RevoRing seizes up? Is the product still safe to use? **

If the RevoRing rotation encounters a problem where the blades do not retract due to issues with the springs, then it should not be used on the lens as there will not be enough tension to hold the blades in place.

Q. Can the RevoRing take filters other than 67mm or 82mm on each size? Can I use a step up ring on the RevoRing as well? **

RS49: for lenses from 37mm to 49mm, use a 52mm round filter

RS62: for lenses from 46mm to 62mm, use a 67mm round filter

RS77: for lenses from 52mm to 72mm, use a 77mm round filter

RS82: for lenses from 67mm to 82mm, use an 82mm round filter

RS95: for lenses from 82mm to 95mm, use a 95mm round filter

For those sizes, you could conceivably use a step up ring from these filter thread sizes to fit a filter that you have, however, an added step up ring may cause potential vignetting. 

Q. When does vignetting occur on the RevoRing 46-62mm and 67-82mm? **

In general, all lenses from 46mm to 62mm will not vignette when using the RevoRing. This is because the RS62 RevoRing is using a 67mm filter on the front. When using an RS82 RevoRing and an 82mm filter, vignetting will occur when using an ultra-wide lens. For example, when using 16mm and 14mm on Sony 16-35mm F4.0 and Nikon 14mm-30mm F4.0, attaching the 82mm filter directly onto the lens, will avoid or reduce vignetting.

Q. What is the widest lens I can use without vignetting? Will putting a filter on the RevoRing also increase the chance of vignetting? **

As with all filters, the choice of camera and lens along with filter being used (especially Variable Neutral Density filters) will determine whether vignetting will occur. 

Q. What happens if dirt gets inside the RevoRing? Is it Sand-proof? Mud-proof?

The RevoRing is a technical variable adaptor ring, made up of clever retractable blades and spring coils. It should be treated with care, just like your lens. You should always put a cap on your lens barrel to protect it from dust particles and sand. We will be making a slip-on cap to be used to protect the RevoRing, so that when carrying your RevoRing, it will be protected from dust and sand. 

Q. What happens if water or liquid gets inside the RevoRing?

The RevoRing is made up of 6063 Architectural Aluminum and is more resistant to corrosion. However, just like your lens, you should avoid water and liquid at all costs! We will be making a slip-on cap to be used to protect the RevoRing, so that when carrying your RevoRing, it will also be protected from water entering the RevoRing. 

Q. How strong is the RevoRing?

The RevoRing is fit for the purpose intended, which is to mount filters onto lenses. Whilst it can take quite a load (you can actually pick up the camera and lens by holding the RevoRing alone), we do NOT recommend that you do this, because you will be exerting force on the lens threads and could damage those threads. 

Q. How do I look after the RevoRing?

There is no need for any special treatment! You just need to keep it clean and prevent contact with dirt, sand and water, just like your lens.

Q. Can I get this RevoRing serviced, or can I carry out the service myself?

For warranty issues, the RevoRing will be handled by our dealers or directly. We do not recommend you open the unit up, because you will not be able to close it again. 

Q. What happens if the RevoRing is used in cold climates like the top of mountains? 

The aluminum alloy of 6063 can withstand extreme cold and heat climates relative to the person using the RevoRing. 

Q. Do I need to lubricate it in cold weather?

The lubricant already applied to the RevoRing internally is resistant to extreme cold and heat

Q. What happens if the RevoRing is exposed to really hot climates like in the desert?

The aluminum alloy of 6063 can withstand extreme cold and heat climates relative to the person using the RevoRing. The key concern would be to prevent dirt and sand getting into the RevoRing and your lens.

Q. Is the RevoRing dangerous to use? Is it sharp? **

The RevoRing is circular in shape and has no sharp edges, other than the blades that retract on the back of the product. Care should always be taken when rotating the diaphragm and releasing the it, causing the blades to retract.

Q. Can I leave the RevoRing on my lens when travelling?

You can leave the RevoRing on your lens when travelling, however you just need to ensure that your bag is large enough to fit!

Q. What do I do if I drop the RevoRing and it bends?

If the product is bent due to improper use, we suggest you purchase a new one.

Q. Can I rinse it in water if it gets dirty?

No, just like your lens, we only recommend that you use a cloth to clean off dirt.

Q. Can I clean it with alcohol? Acetone?

No, just like your lens, we only recommend that you use a cloth to clean off dirt.

Q. Can I stack filters on the basic RevoRing?

If you filters allow for stacking on top, then you are able to do this on the RevoRing, however you will increase the chance of vignetting.

Q. Is there a case for the RevoRing? with filter attached?

We make a premium aluminum cap which is available in the store.

Q. Can I add a lens-hood on the filter I place on the RevoRing?

You will not be able to use the lens hood (that may come with your lens) after a RevoRing is used on the lens.

Q. Are there any light leaks with the RevoRing?

No.

Q. Can the RevoRing work with bent filter threads on a lens? How is this possible? Won’t the sections all remain open and not touch the threads completely? **

This will depend on how badly bent the filter threads on the lens are. When applying the RevoRing onto the lens, upon releasing it and rotating the RevoRing a little, if it is able to engage threads and holds in place, then it will be possible to use the RevoRing even if the threads do not allow for proper threading of a filter.

Q. How do I set the Polarizer and Variable ND?

We recommend that you set your level of ND first. You do this by adjusting the front filter, between the MIN and MAX marks, and in accordance to focal distance so that you do not reach the X cross point, which is created when two polarizing filters work together to increase the level of ND. Thereafter, you can turn the CPL filter (which also turns the ND filter which is already set) to desired level.

Q. Does this RevoRing VND produce an “X” Cross? **

All Variable ND filters that use two polarisers will form an Extinguishing Cross, or X Cross, at a certain point, and dependent on the focal distance being set on the lens. We have put a “W” mark to signify the maximum setting level for wide angle lenses, and we are in process to produce other marks to allow you to determine the maximum level dependent on your focal distance. For example, a focal distance of 200mm will achieve more levels of light reduction than a focal distance of 16mm, before the X cross appears in picture.

Q. What does the “W” mean on the VND ring?

The “W” mark on the filter ring signifies the maximum level of ND that can be applied when using a wide angle lens, before the X cross appears in picture, which is an inherent issue with using two polarisers together to create ND.

Q. What is the widest lens I can use without vignetting? **

For the RevoRing VND 67-82mm on an 82mm thread lens, we recommend 18mm or above.

Q. Can you lock the VND ring? **

We will have hard stops for the RevoRing VND, but we will not have position locks for the individual filters (VND and CPL). We will be making the filters stiffer to turn against the RevoRing itself, giving a tighter turn and keeping the position of the filter.

Q. Can you lock the CPL ring?

We will have hard stops for the RevoRing VND, but we will not have position locks for the individual filters (VND and CPL). We will be making the filters stiffer to turn against the RevoRing itself, giving a tighter turn and keeping the position of the filter.

Q. Is there a colour shift with the VND? **

An automatic white balance will not show color shift. A manual white balance will appear as a slightly warm color temperature

Q. Can I add a lens-hood on the VND+CPL?

When you fit a RevoRing VND onto your lens, you will not be able to use the lens-hood that comes with that lens. 

Q. What does the MAX level actually mean? Does this differ between the lenses I can use with my camera?

The MAX level is the point where the VND can go before the X Cross appears in picture, for all focal distances. The actual MAX level is dependent on the focal distance being set on the lens being used. This means that a lens with a focal distance of 200mm will have a different MAX point to a lens with a focal distance of 16mm.

Q. If I use this RevoRing VND, does the minimum level give me zero stops, or is there an immediate light stop introduced if I put this on my lens? 

The “MIN” point of the VND effectively means ND3, which is a 1.5 stop reduction.

Q. What does ND3-1000 mean? I thought a VND was made up of two polarisers?

ND3-1000 means a 1.5 to 10 stop light reduction, achieved through combining two polarisers together. When the polarisers are turned on each other, it will increase the level of ND, hence increasing the level of light stops. Depending on the focal distance of the lens, you will achieve different maximum levels of ND before the X cross appears in picture.

Q. What happens if moisture gets in between the glass on the RevoRing VND?

Care should be taken in ensuring that your RevoRing VND is protected from such environments, just like your lens. If the product is still under warranty, contact us for after sales service, as the product will need to be repaired by the factory. It cannot be opened. 

Q. Can I remove the VND or CPL filter?

The RevoRing VND is a sealed unit and cannot be opened.

Q. What do I do if I scratch the front filter surface?

Scratching filters or lenses is never a good thing. Whilst lenses can be repaired as they are expensive (and new glass fronts are not cheap when accompanied with the labor charges), scratches to filters cannot be repaired.

Q. Do you have a hard stop on the MAX level?

There will be a HARD stop at the MAX point shown on the filter ring. We are also thinking of adding a Hard stop on the MIN point as well. This restricts the movement of the VND filter, and helps give the user a better sense as to where they are within the ND3-1000 range. 

Q. How can I clean between the glass?

You are able to clean the glass on the exterior side (both sides have 9 layers of coating). However, you cannot open up the RevoRing VND.
