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?

A very mobile phone

It took me a few hours before I realised just how close I and my daughter came to being injured or even killed in Derby's Market Place today. It wasn't really the fault of the young lads on the ride. In fact, it might have been my unwarranted suspicions of them that actually prevented us getting hurt...

...My daughter and I had crossed Derby's Market Place and had briefly stopped to look at the huge spinning ride that had been installed there - just like the one shown below. It was empty at the time but, by the time we returned, she saw it now had passengers on board, and was about to start moving.  She wanted to watch. We noticed it included a group of young lads who we'd seen earlier on that day at the Intu centre, messing around on the escalators. Nothing serious - just kids. She stopped to watch as the ride started up. It was then that I realised we were standing directly in front of it, edge-on, and looking right up towards it. Oops - we were potentially in the line of fire from anything that come might come flying from them!

I suggested we stand a few feet off to one side as it began rotating. "Why?" she asked, and so I replied that I didn't like the idea that one of them might try something stupid, like trying to spit on people below, or whatever. So we moved in a bit towards the cafe under the Assembly Rooms, and watched from there. (I think she thought I was daft, but that's the kind of thought processes caring Dad's go through.)

Could you be wiped out by items flying off from 'Speed' attractions like this one?
After a few rotations of the fast-spinning arm, we realised the chairs themselves revolved, too, with punters turning right over. Those really aren't the kind of rides I enjoy these days (you can tell I'm getting to be an old git, because who else says "these days", these days?) Suddenly there was a crash on the flagstone just in front of us, and there lay the perfect result of centrifugal force at work - someone's smartphone, completely smashed into pieces, and either forced out of their hands or ejected from the back pocket of one of the unlucky punters above us. At the time I felt sorry for them, so I collected up the bits and took them over to the control booth and handed them in. The look I got from the man in charge was almost one of "oh well, what do you expect? Stupid customers. Happens all the time". He didn't say that - but his expression did. It spoke volumes.

I went back to my daughter, and almost immediately there was a second dull thud. This time 5p pieces rolled across the flagstones. It sounded like someone's leather wallet had hit the ground and burst, although a quick glance round amongst the empty cafe seating didn't reveal anything. By now it it was starting to feel too risky to stick around. We quickly left.

It was only later, as I recounted the incident to my wife, that it struck me there really are some safety and management issues that need to be addressed here.

  • Where were the clear warning signs telling customers not to take loose items (wallets/phones etc) with them? 
  • Who's responsible for checking customers and holding on to these items? 
  • Why are the public not prevented from passing directly underneath these rides, or in the line of objects that might hurtle out from them? 
  • Who checks and licences these rides? 
  • And who would have been responsible had one of us been injured as a result of such poor ride management?


I feel sorry for the person who lost their phone today. (though not if they were using it at the time!) However, the idea of anyone being hit on the head, edge-on, by a fast-flying smartphone really doesn't bear thinking about. Nobody would stand sideways on to a catherine wheel whilst it's spinning around, but why was it so easy to pass in front of the fairground equivalent? These Speed rides reach forces of up to 3.5g (see here and here). There will be a phone call to the safety and licencing team at Derby City Council in the morning, assuming there's anyone still employed there these days.

Meanwhile, anyone with a hard hat and a few hours to kill could make a tidy profit by sitting in the outdoor cafe in the Market Place this week. You never know what valuable objects might fall into your lap.

Update: 3pm.  I've since received a courteous reply from Derby City Council, who have now spoken with the site managers. I've replied to say that I'm still not convinced from their response that enough is being done to discharge the duty of care to passengers and passers-by.
