Faulty Jessops filters?

I recently returned to SLR photography after a break of over 15 years. It probably took me three years to finally get around to choosing the right camera. Projects like publishing my new Flora of Derbyshire did rather keep my focus elsewhere, if you pardon the pun. It was only when I bought a Canon EOS 110D from Jessop's for my daughter's birthday that I began to realise what I'd been missing. So more hours were then spent poring over reviews and pricing websites - but this time for me!

The chaps in Jessops in Derby were superb. Lots of time to talk me through my preferred choices, and I eventually opted for my first choice: a Canon EOS 760D with Canon's own 18-135mm lens, and a second Canon 10-18mm lens. They both seemed very well reviewed as first lenses, and I saw no point in buying the kit lens with it. Jessops prices were competitetive, too. It did however make sense to buy a 67mm UV filter for each  of these zoom lenses, just to protect and keep the lenses clean, if nothing else. So, two Jessops own-brand filters were immediately fitted, and I also bought a Jessops own-brand 67mm polarising filter. Such a useful first accessory to play with!

The UV filters fitted perfectly, and of course, for best optical results one would remove the UV filters and replace it with the polarising filter. But they should also work well by being stacked together, and this is where the problem lay.  Although initially screwing on perfectly, the Jessops polarising filter failed to stop screwing round. It should have mated up and then allowed me to rotate just the polarised element. Instead, the whole thing kept turning, clearly jumping the thread each turn.

I tried it on the other lens and filter, and the same problem occurred. It wouldn't lock on the UV filter's screw thread, though it did lock properly straight onto the Canon lenses themselves.

I tweeted to Jessops, asking if this was a known issue. Their reply was negative, and was advised to speak to the local branch. So I went in yesterday and the friendly Derby staff quickly appreciated the problem, suggesting that for best results one should use one filter or the other. But we did both agree we would have expected them to fit one another properly.We tried another filter from the shelf, and this exhibited exactly the same problem. So it looked like a batch fault in the manufacturing was the cause of the problem. The staff member then suggested maybe this was an intentional design feature, perhaps to avoid damage to the screw thread. But that made no sense - a slipping thread does more harm than one that fits screws tightly. Nor did I ever experience this problem all those years ago int he days of 35mm film and my trusty Minolta X700 camera.

So, back to Jessops on Twitter and we'll await to see what response they give.
Oh - brill - just as I'm finishing writing this they've asked be to DM them my email address, so you can't say fairer than that for responsive customer service, can you?
