LEE Filters 105mm Front Holder Ring

Its primary purpose is to allow the attachment of a 105mm threaded accessory, most commonly a polarising filter, to the front of a LEE 100mm filter holder system. This enables independent rotation of the polarizer.

No, the LEE Filters 105mm Front Holder Ring only provides the mounting mechanism. The 105mm rotating polariser must be purchased separately.

This ring is specifically designed to fit onto LEE Filters' 100mm standard filter holder system, such as the Foundation Kit.

A standard 100mm polariser would be a square filter that sits within the filter holder slots. This 105mm accessory allows you to use a round, threaded polariser that attaches to the front of the holder, offering independent rotation and often a wider range of adjustment.

It is most beneficial for landscape photographers who use LEE's 100mm system and require precise control over reflections and sky saturation using a 105mm threaded polariser, especially in conjunction with other filters like graduated NDs for long exposures.

Clean it with a soft, dry microfiber cloth. Avoid using liquids or abrasive materials.

You can attach any 105mm threaded accessory, though a polariser is the most common application. Lens hoods designed for 105mm threads could also potentially be used.

Ensure you are using a compatible LEE Filters 100mm holder and that the ring's mounting points are clean and free of debris. Verify the ring is correctly aligned before attempting to secure it.

Check the threads on both the ring and the accessory for any damage or obstruction. Gently try to thread the accessory, ensuring it is not cross-threaded.

Confirm that the accessory is fully screwed into the 105mm holder ring and that the ring itself is securely attached to the main filter holder.
