This special ring will adapt the LEE Filters 100mm System Filter Holder to fit the Canon 17mm TS-E lens and will allow more than half of the total amount of movement that is normally possible with this lens before vignetting.
Lee Filters feel that this is plenty for most uses and using the smaller 100mm system will allow the use of popular 100mm filters such as the Big Stopper and Proglass range.
