Q1) Will I get vignetting when I use filters with my lens?

A: With so many different combinations of wide-angle and zoom lenses, cameras, filters, filter holders, and other factors, it's difficult to predict under what circumstances vignetting will occur, and to what extent. As a general guideline, when a lens has a focal length of under 20mm (35mm equivalent) shooting on a full-frame camera, there is a chance that you'll experience vignetting with a standard ring-mount filter or a standard Cokin filter holder. Again, this is only a general guideline -- it's possible to avoid it with shorter lenses, or encounter it with longer lenses. Even the distance at which you're focusing can be a factor.

The more important question is, what positive benefits will the filter provide for your images? Are those benefits worth the tradeoff of potential vignetting? How essential is it to shoot at your widest angle? If you are aware of the issue ahead of time, you can adjust your shooting position or your composition to work at a "safe" focal length. You could plan to crop the images slightly, maybe even going for more of a "panoramic" cropping.

Vignetting concerns were more serious in the days of shooting film, because there was no preview, and viewfinders showed a smaller percentage of the frame, so you might not see vignetting until you'd processed the film and it was too late to do anything about it. Since your digital camera gives you an instant full-frame view of the shot, again, it's now a simple matter to compensate for it while shooting. (top)


Q2) What filter holder do I need to use for ND Grads to avoid vignetting?

A: As explained above, the answer is "it depends." Actually, with ND Grads, it's the filter holder that may cause vignetting, not the filter itself, so it's easy enough to test if a particular combination of lens, camera and holder will be satisfactory before you actually purchase a filter. If you have a local camera store, you can take your system in and do a few test shots with the various holders. Or they are not terribly expensive to purchase online and test.

In their P-size (84mm width), Cokin makes a standard 3-slot holder, and a single-slot "wide angle" holder, both of which are very affordable. Generally speaking, there is less vignetting when wide-angle lenses are fitted with a Cokin Z-Pro or a Lee holder, which both use larger filters (100mm width) and offer several configuration options. These larger holders are more expensive, as are the filters themselves. Singh-Ray offers a number of filters in this size.

Many pros that we work with prefer to hand hold their ND Grads, partly to reduce chances of vignetting, but also because it's faster, offers more control, and is less gear to carry and deal with in the field. Some will also lightly use gaffer's tape (non-residue) to position the filter in front of the lens. You can read more about it on our blog: http://singhray.blogspot.com/search/label/hand%20holding (top)


Q3) Do you sell Cokin Filter Holders?

A: No, we do not carry filter holders at this time. They are available from most full-service camera stores, or online dealers such as B&H Photo. (top)


Q4) How thick are your filters? What is a "thin mount" filter?

A: Singh-Ray ring-mounted filters have different "profile thicknesses" depending on the nature of the filter. The profile thickness is the barrel thickness, not counting the male threads that recess into the front of the lens. Our standard ring mounts have front female threads that allow you to mount another filter in front (this is called "stacking" filters). Our thin mount rings do not have these front threads -- by eliminating these threads, we're able to reduce the profile thickness by a few millimeters, thus reducing the chance for vignetting.

Here is a listing of profile thicknesses for Singh-Ray filters:

LB Color Intensifier, Hi-Lux, Mor-Slo, A-13 Warming, I-Ray, Soft-Ray* (non-rotating)
- Standard mount: 5.5mm
- Thin mount: 4.6mm

LB Warming & Neutral Polarizer, Gold-N-Blue (rotating filters)
- Standard mount: 8.6mm
- Thin mount: 4.8mm
- 105mm Standard mount: 11.1mm
- 105mm Thin mount: 7.0mm

LB ColorCombo (rotating filters)
- Standard mount: 8.6mm
- 77mm Thin mount: 4.8mm
- 82mm Thin mount: 5.5mm

Neutral Density Grads, Reverse ND Grads, Solid NDs
- All sizes: 1.5mm

Vari-ND
- Standard mount: 14.1mm
- Thin mount: 10.4mm

Vari-N-Duo
- Standard mount: 17.3mm
- Thin mount: 14.7mm

Vari-N-Trio
- Standard mount: 17.3mm
- Thin mount: 14.7mm

PLEASE NOTE: because there are no front threads on thin mount filters, standard "clip style" lens caps will not work with these filters. We have "push-on" lens caps available for sale here: http://www.singh-ray.com/pouches.html -- also, other filters can not be mounted to the front of these filters.

NOTE: profile thickness specifications subject to change/variance without notice.

Also, stacking filters is more likely to lead to vignetting of your images shot with wide angle lenses. (top)


Q5) What are your filters made of?

A: All Singh-Ray products are made to the highest quality standards for optical integrity. Our rectangular and square filters (ND Grads, Reverse ND Grads, etc.) are made with high-quality optical resin, the same material used in prescription eyeglasses.

Our ring-mounted filters are made of highly polished glass and specially formulated optical laminates and other components, depending on the filter. (top)


Q6) Are your filters multi-coated?

A: No. We have carefully evaluated multi-coating of filters, and in our opinion, the benefits are negligible, and outweighed by several disadvantages. (top)


Q7) What filter sizes are available?

A: All our ring-mount filters are available in 77mm, and some are available in 82mm, 72mm, 67mm, 62mm and 58mm. Our rectangular graduated and solid neutral density filters are available in 84mm (Cokin "P") and 100mm (4x6-inch) for Lee and Cokin Z-Pro holders. To see what sizes are available for various filters, visit: http://www.singh-ray.com/table.html

Some smaller sizes are available on a custom basis and may require a surcharge and additional time for delivery. LARGER sizes are not available due to manufacturing limitations. If we are able to make larger sizes in the future, we will update our website and blog, but there are no plans to do so anytime soon. (top)


Q8) How soon will I get my order?

A: Producing our filters requires a substantial amount of hand-crafting, to the extent that they are essentially "made to order" rather than pulled from mass-produced inventory. While we make every effort to ship filters as quickly as possible, we do ask that you allow up to 10 business days for your order to ship.

At times, our exacting quality control standards may lead to a delay in shipping a particular type of filter. Your credit card is NOT charged until your order is ready to ship. (top)


Q9) What is your return policy?

A: Due to the nature of our products, all sales are final. Singh-Ray filters purchased directly from us are warranted against manufacturing defect for 90 days from date of receipt. In the event of a manufacturing defect, the filter is to be returned to Singh-Ray for inspection and repair or replacement at our option. Please contact us before sending a filter back for warranty service. Filters that are damaged due to exposure to extreme temperatures, being "baked" in intense direct sunlight, dropped, submerged, improper handling, or other forms of neglect are excluded from our warranty.

If you purchased your filter from a dealer or other third party, any quality concerns should be directed to the seller according to their policies. (top)


Q10) My filter is scratched, what do I do?

A: Filters do sometimes get scratched in normal handling. Most scratches that can be seen when looking at the filter are not visible when shooting THROUGH the filter, because your lens' focus point is anywhere from a few feet to hundreds of yards past the plane of the filter. Generally, it has to be a pretty severe scratch, or a lot of light scratches, before you experience problems with your image. Take a variety of test shots to see if the scratch you see is really a cause for concern. If so, it may be time to replace the filter.

We do NOT recommend eyeglass scratch filler kits sold at drugstores for use with our filters. They are likely to cause more problems than they solve. (top)


Q11) Do you have a dealer in _______?

A: Our online store is our primary dealership, or you can order by phone at 800-486-5501 (toll-free in USA) or 863-993-4100. Singh-Ray does sell selected filters through B&H Photo in New York, and through the Mountain Light Gallery store in Bishop, CA. Our dealer in Canada is The Camera Store (thecamerastore.ca). No other dealerships are currently available or planned. (top)


Q12) How are your filters packaged?

A: Singh-Ray filters are placed in a clear plastic bag which is taped shut, which is then placed in a soft leatherette pouch lined with special microfiber cloth, and the pouch is sealed in plastic. When you receive your filter, remove the plastic seal, and remove the filter from the clear plastic bag and discard the plastic. It is safe to store your filter in the pouch as long as you are careful to keep dirt, sand, or other substances from getting into the pouch to potentially damage the filter. Replacement pouches are available here: http://www.singh-ray.com/pouches.html (top)


Q13) I'm getting a color cast with my Neutral Density filter. What's the problem?

A: When using a Neutral Density filter (graduated or solid) you are generally causing your camera to make a longer exposure than normal, sometimes much longer. The software in some digital cameras uses response curves that adjust the RGB sensors sensitivity based on the exposure time, which may introduce more red into the image. Sort of a digital form of reciprocity failure. In other instances, blocking visible light and a longer exposure allows infrared light to "build up" on the red sensors leading to a red or purple-ish cast. If your filter looks neutral but you see the cast in your images, try taking some test shots using the filter with a different brand of camera, or with a film camera. If you still see the cast, and you're within the warranty period, contact Singh-Ray to have your filter evaluated and possibly repaired/replaced. (top)


Q14) I'm just getting started with filters. What filter do you recommend I purchase first?

A: In part the answer depends on the types of images you're planning to take. However, our LB Warming Polarizer is the filter that can benefit virtually every outdoor photographer, by helping to reduce glare and improve color saturation of skies, lakes and streams, and wet surfaces. It can even let you see objects below the surface of water.

For Graduated ND Filters, there are various opinions as to which to start with. The idea is to help balance the exposure by "holding back" the brightest area of a scene (usually the sky) so you can brighten your exposure for the foreground. Each density can be valuable depending on the lighting situations. Hard-steps are best suited to flat horizons, such as deserts and over water. Soft-steps are best for horizon lines that are uneven, or broken up by trees or hills, etc.

To start with, a good choice would be a 2-stop hard-step, and a 3-stop soft-step. Each will make a definite visible difference in your viewfinder that you'll be able to see to properly position the filter, but they are still subtle enough to be forgiving if you don't position them perfectly at first. With practice, you'll learn to use them, and figure out what other filters you want to add to your arsenal. (top)


Q15) What's the difference between an ND Grad and a Reverse ND Grad?

A: Graduated Neutral Density filters are often called ND Grads, GND, Split filters, or by other terms, but in general they refer to a gradual transition from clear to dark, with the darkest point of the filter being the nominal density of the filter. For instance, a 3-stop ND Grad adds 3 stops of density at the darkest point near the top of the filter and transitions to clear near the center of the filter.

A Reverse ND Grad is a specialized version where the darkest area is in the CENTER of the filter and transitions to about 1 stop lighter at the top of the filter, while the bottom portion of the filter is clear. This is especially useful for sunrises and sunsets, to "hold back" the sun at the horizon, and balance the exposure with the foreground below the horizon, and the sky towards the top of your frame. (Turning a standard ND Grad upside down would result in having the edge of the filter in frame -- not the effect you want.) A Reverse ND Grad is similar to our Strip Filters, which have a dark band across the center, but are nearly clear at the top portion of the filter. (top)


Q16) Why are your ND Grad Filters not square?

A: The added length of our ND Grads (84x120mm or 100x150mm) allow you to position the horizon of your image near the top or bottom of your frame to fit your composition. Square or ring-mounted ND Grads from other manufacturers basically limit you to positioning your horizon at dead center of your frame, leading to boring composition. (top)


Q17) I have a 14-24mm f2.8 Nikkor lens. It doesn't have a filter thread -- how do I use filters with it?

A: This lens has clearly been designed NOT to accommodate filters, as are several other specialized lenses released over the years. We are not able to engineer a method for using filters with these unusual lenses. (top)


Q18) Do you sell filters to fit my Hasselblad lenses?

A: Hasselblad has a proprietary bayonet system for mounting filters onto its lenses. You can purchase adapters from other dealers that will allow you to mount standard size screw-in filters or the Cokin filter holder. (top)


Q19) I have a question not addressed here...

A: If you have product questions that are not addressed here or on the product page online, please download and review our online brochure. If you still have questions, please phone 800-486-5501 (toll-free in US) or 863-993-4100, or send your question to: srstore@singh-ray.com (top)
