There I was sat on the rocky shore at Craster taking photos, gets my Lee filter holder out and the brass clamp falls to bits and into the rocky nooks and crannies. Any chance of finding the pieces - errr, no !

So, on Monday I rang Lee Filters customer services up to see if I could buy replacements parts, and the very nice lady said they would send me some in the post - free !

The clamp parts arrived yesterday and are just the job. So, I'm back in business - good on 'ya Lee Filters.
