1 Independent Review - Haida 150mm Filter System By Daniel Gangur Over the past couple of months I have been using Haida s 150mm filter system, these optical glass filters are perfect for use with ultra wide-angle lenses. I initially saw these filters at a trade show last year and was interested in the fact they offered a filter adapter that suited the Samyang 14mm f2.8 lens. The Samyang 14mm f2.8 lens has a large bulbous front element that requires a dedicated filter adapter and large 150mm filters if you wish to use filters on this lens. Just in I ve also recently found out that Haida is releasing a dedicated holder for the new Samyang XP 14mm f2.4 lens, so hopefully I will be able to get one of these for test soon too. Haida offers these filter holder kits for a variety of ultra wide-angle lenses, more information can be found here, They also make a variety of filter ring adapters to suit various screw in front filters thread diameters that can also be found at I was lucky enough to receive a pretty thorough set of filters and adapters from Haida Australia to suit my most used lenses for review. The kit includes, 1 50mm universal filter holder and 77mm filter adapter ring 1 50mm filter holder set to suit the Samyang 14mm f2.8 lens 150 series insert filter pouch 0.9 soft, hard and reverse PROII Multi Coated Graduated filters (3 stop) 0.9 Neutral Density filter (3 stop) 3.0 Neutral Density Filter (10 stop) Insert Circular polarising Filter Initial thoughts One thing that was immediately apparent when I opened up the nice clean white Haida packaging was the hard metal case each filter comes in, fantastic! These metal cases look great, are quite minimalist with just the Haida logo, but most important of all give each filter protection from damage, my LEE filters never came packaged like this, well done Haida. Everyone I ve shown these filter to has been equally impressed. Haida has consistent looking packaging for their filter adapters, filter pouch and filter adapter rings although these do not come in the metal case like the filters it is clear that Haida aim to make a quality product.

2 The dedicated filter adapter kit for the Samyang 14mm f2.8 comprises of three parts, the filter holder, an adapter ring and collar. The collar slips over the back of the Samyang 14mm lens and screws to the adapter ring that sits on the front of the lens using small locators to position it in place on the petal lens The Haida filter holders are made of metal with a matte black inner to help stop reflections. The Samyang dedicated holder on the left (above) has one filter slot to help minimise vignetting. The universal holder (above right) has two to allow stacking of filters. Both have gaskets to ensure no light leaks in around the filters when placed in the first slot, each holder comes with plenty of spare gaskets, another nice touch by Haida. Either filter holder can be used with the dedicated Samyang 14mm f2.8 adapter or screw on filter adapter ring but you will get vignetting with the Samyang 14mm f2.8 lens if you use two filter slots. Something I really like about the Haida system is the hood of the lens. Once screwed together the filter holder simply slips on and is locked into position. There are instructions included with the filter holder kit but it s very straight forward. You can leave the Filter holder attached to the adapter ring and leave the collar on the lens if you wish while it s all in your bag between shoots. Above - filter/holder adapter ring and collar looks very tidy and offers the ability to use 150mm filters on ultra wide angle lenses that do not offer front filter threads. way it pieces together. The filter holder slots onto either the adapter ring or dedicated adapter via 3 locators, once slotted in, you rotate the holder slightly and then screw in the locking screw (shown above) this holds the holder and filter in place on the lens. It allows you to loosen the screw to allow rotation for filter positioning or you can screw the locking screw in further to hold the filter holder and filter in place. The way it is designed means that even if you totally unscrewed the locking screw the filter holder and filter would not easily fall off, a big concern when using large expensive glass filters, I really like this system.

3 Haida Insert filter pouch The filter pouch purchased separately for the Haida filters holds six filters in dedicated soft slots in one side of the pouch. The pouch is still essentially soft but does offer quite good protection, it would take a fair hit to break any filters, each sleeve is very soft, providing it s kept clean your filters should be kept safe and in good condition, the filter area zips closed to keep dust etc out. There is a front area in the pouch that fits your holder and adapter ring or dedicated filter adapter kit. A large flap folds over this area to keep everything inside and offers a bit more protection along withe easy access. The pouch also has a shoulder strap with quite solid clips and fittings, the material the pouch is made of looks quite water resistant and easy to keep clean. The pouch is simple but functional and definitely worth purchasing as it s a lot easier to carry than six metal cases and also uses up a lot less space in your kit when packed. Above Inside the filter pouch. The Filters The Haida 150mm graduated neutral density filters allow you to reduce exposure in selected areas of your image to balance exposure, these are available in hard, soft and reverse and in various strengths. Above is the PROII Multi coated 0.9 (3 stop) Reverse Graduated Filter, note the darker area in the centre shifting to lighter at the top, good for reducing the exposure just above the horizon in sunrise/sunset images and gradually allowing more light in toward the top of the image, the bottom is totally clear and has no effect on exposure. The 150mm PRO MCII graduated filters are made of high quality optical glass that produces no colour shift, approx 2mm thick and suitable for most 150mm filter holders, such as LEE. They are 150mm wide by 170mm long allowing you to slide them up and down in your filter holder to suit the scene and reduce exposure where you would like, a definite advantage over screw in round filters that do not allow this. The filters are multi coated to reduce light reflections, they also have a water proof coating, I believe this may be to help keep the filter clean. The Haida ND (Neutral Density) filters reduce the amount of light hitting your cameras sensor, darkening the scene. This allows you to use a wider aperture or longer shutter speed, these are available in various strengths like the graduated Neutral density filters. This is useful for creating silky smooth water, show movement in clouds etc. The Haida ND filters are made of high quality optical glass, approx 2mm thick to suit various 150mm filter holders. They are 150mm x 150mm as they do not need to be moved in the holder. They do not effect the colour of an image. The Haida Circular Polarising Filter is also made of high quality optical glass, 150mm x150mm and 2mm thick and can be used in various 150mm filter holders. A circular polariser can cut out glare from a scene, reducing/eliminating reflections, it can help saturate colours, deepen blue skies and emphasise clouds, it can also darken the scene, very useful.

4 My experience using the Haida filters In use I found the Haida filters did not introduce any strong colour casts, drop of image quality or purple fringing. They are extremely easy to keep clean with just a lens cloth or with bit of fresh water and cloth to remove salt spray or stickiness from grass seeds etc. I also didn t have any issues with light leakage/ reflections when using the ND filters for long exposures. There was some very slight vignetting at 17mm using my Canon full frame and 17-40mm L lens but I would expect this with most 150mm filters/filter systems. There was some more severe vignetting when using the dedicated filter holder on the Samyang 14mm f2.8 and Canon Full frame camera. Haida claim there is no vignetting using the single slot on the dedicated holder but it is there, I tested a couple of times, but in real life use it s a simple crop to remove the vignette. Given the design of the Samyang 14mm f2.8 lens I can t see any filter holder doing much better and there is very few options out there. Above is a straight out of camera shot taken with a Canon 6d, Samyang 14mm f2.8, Haida dedicated filter adapter set and Haida Soft Graduated ND. It shows the vignetting using this set up on the Samyang 14mm f2.8, easily cropped out as you will see in the next image. There is no vignetting at all when using this combination on my Canon APS-C camera. This is the previous image cropped with some simple post processing in Lightroom, no lens correction. As you can see with a simple crop the vignetting is gone and very little of the image is lost. For those using the Samyang 14mm f2.8 the Haida dedicated 150mm filter kit is a great option.

5 The above image is straight out of camera, dust and all, no post processing. This is taken with a canon 6d, Canon 17-40L lens using the Haida universal holder, 77mm filter ring adapter, Haida C-Pol and ND stop filter. Settings 17mm, f16, 20sec, iso100. This is where a lot of 10 stop filters show a strong colour cast but the Haida filter does a great job, pretty neutral with no obvious colour cast. This image shows some vignetting, a lot of this vignette could be corrected in post. The above image was taken using a Canon 6d, Canon 17-40L, Haida Circular Polariser, Haida universal 150mm filter holder attached by the Haida 77mm filter adapter ring. 17mm, f16, 1/45 iso100. Nice even exposure across the frame, sharp details.

6 Again the above image was taken Canon 6d, Canon 17-40L settings 17mm, f15, 10sec, iso100. Using a combination of the Haida C-Pol and Haida ND0.9 I was able to reduce the shutter speed during the day to 10 seconds showing movement in the clouds. The second filter (ND) has added some vignetting, no loss of detail. Again with the same combination of camera, lens and filter holder, this time using the Haida C-Pol and Haida ND3.0 (10 stop) Neutral density filter. Settings 17mm, f16, 20sec, iso100. Using the ND3.0 10stop filter I was able to really reduce the shutter speed to 20 seconds, showing a lot of movement in the clouds. Again there is some vignetting but no effect on image quality.

7 Above - gaskets to prevent light leaks when using the ND filters, each ND filter came with a couple of spares, again great to see Haida do this.

8 Conclusion After using the Haida 150mm filter system over the last couple of months I have been really impressed, I haven t used every filter in the kit, but what I have used has been great. Apart from the easily corrected vignetting with the dedicated Samyang 14mm f2.8 holder kit I m really happy with this system. The holders and adapters are solid and well built, the locking screw on the holder is secure, much more secure than other holders I ve used, the dedicated filter holder kit for the Samyang 14mm f2.8 screws together tightly. The pouch and individual storage cases are great and really top off the system, did I mention how nice it is to have a solid individual metal case for each filter to keep them safe, other filters I have purchased have come in single soft cases or just a plastic slip, the metal cases are a fantastic touch, functional and look great. Colour cast and reflections are something I have had issues with in the past from other filters I ve used, this is a reason I don t use filters often, but the Haida filters do not introduce any colour strong casts and I didn t notice any strange light leaks or reflections in any shots using the Haida filters. I also found the Haida filters very easy to keep clean, a simple wipe with a lens cloth removes any marks, salt etc. If you are looking for a 150mm filter system to suit your ultra-wide angle lenses this is a fantastic system and well worth considering.
