LEE Filters launched in Autumn 2013, an adaptor ring to allow the 100mm foundation holder to be used on the Canon 17mm TS-E lens.
This adaptor will allow roughly 50% of the full movements before vignetting, which we believe will be enough for most landscape / architectural situations.
There will always be some restriction when using filters on a lens of this type, but we believe using the 100mm system, with access to our full range of filters (Stopper, Polariser etc.) with some restricted movement, is the ideal compromise.
This new ring can be ordered from your LEE dealer now.
