Lee filters announced a new addition to their Lee 100 filter holder system today. The new development is quite a unique idea that many landscape photographers may have wished possible for a long time. The Lee 100 tandem adaptor basically makes way for a second filter holder to be mounted on top of the first.
In the above video, it shows that the tandem adaptor uses one of the filter slots to attach a secondary adaptor ring onto the filter holder to be able to mount a second one. This feature is a first across all filter brands and could definitely be a new trend. The point of having a second filter holder is basically to be able to have GND filters in different tilt positions. Doing so could potentially allow for more flexibility in controlling the dynamic range of a scene especially those with more than one significant light sources.
Lee announced the new product on their facebook page along with the information that the new product will be available through their dealers starting Monday, August 5, 2019. The link that leads to the Tandem Adaptor product page on the Lee filters website shows more detailed information as well as a demonstration video of how the Tandem Adaptor works.
The Tandem Adaptor and Foundation Kit with Accessory Tandem Adaptor combo are also already on B&H.
