![]() We do reseller business and if we give too many free options they don't like it. After using the NX filter system, these points seem a small price to pay for the performance.Our problem is that we can't satisfy everybody. With patience, good light, a decent precision screwdriver, and a clear table, the filters can be mounted in their frames ahead of their first use, and it doesn’t take long to work out a way of removing the polarizing filter. There are only really two issues that count against the NX Series Holder, the fiddly screws for mounting the filter frames and the awkward way in which the polarizing filter has to be removed. The Cokin NX Series Filter Holder makes a great choice, having delightful build quality and holding the filters securely. While circular filters, especially those with a magnetic mount, are quicker and easier to use, a holder is required for proper use of graduated filter. If you want to insert a second filter, rest its frame against the first filter’s frame and then slide it into position. This avoids any misalignment or straddling the two rows of ball bearings. I found it helpful to touch the end of the filter frame onto the top of the holder and then slide it onto the row of ball bearings closest to the lens. Now you’re ready to slide a framed filter into the holder. A small metal cog in the Filter Holder engages with teeth in the CPL filter’s frame so that it can be rotated easily while you look in the camera’s viewfinder. If you want to use a polarizing filter, this should be mounted first as it pushes neatly into dedicate circular area in the holder and sits close to the lens. With the holder on the lens it’s time to mount a filter. It keeps the holder securely on the lens. It’s held by two metal tabs, one of which is sprung to allow it to be pulled back while the holder is aligned on the adapter before the clip is released. ![]() Once an adapter ring has been mounted on the lens filter thread, the holder can be clipped onto the adapter. The Starter Kit comes with 72mm, 77mm and 82mm adaptor rings, but you can buy the frame and adaptors separately (Image credit: Angela Nicholson/Digital Camera World) I lost a screw or two in the process, but thankfully, Cokin provides a couple of spares with the frames. The tab is secured on the frame by two tiny screws and though they are easy to remove, refitting them is a frustratingly fiddly job. The filter is held in the frame by a small aluminum tab which must be removed to allow the filter to be slipped in. It’s also something really only want to do once, so it’s well-worth ensuring that you have a frame for every filter that you’re likely to use. This is not something you want to do out in the field. These ball bearings fit into slots in the filter frames so that the filters slide smoothly into place.īefore you use a filter, it needs to be mounted in one of Cokin’s filter frames. Most filter holders have slots for accommodating the filters but the NX Filter Holder has two rows of four ball bearings on either side.
