Whilst this is what I fear could happen, that video at the bottom offers a good backup (like the photo I linked to also).
Looking forward to hearing your analysis on the Q-Strap. How you going to stress test it? lol
I've been looking at the BlackRapid straps and a few of the alternatives and I came across one called a CarrySafe, but it was the mounting plate that caught my interest.
I'm wondering if the ones which screw straight into the tripod mount are perhaps putting an awful lot of local stress on that point on the camera, whereas the ones which use the plates are spreading the load more?
Interesting again: http://www.youtube.com/watch?v=bUK7G5Gy5B4
Although we don't know if it's caused damage and it's just not apparent yet?

Steve, 92kg break strength eh? Nice. Post pics please.
Graham, that vid's quite reassuring -I'm hoping my implementation will be able to make use of that.
Doug - That tripod QR plate screw there? Is that the one that came with the manfrotto QR plate? If so, are you happy that enough of the screw thread is still able to screw into the camera's tripod mount (whhat with the addition of the q-strap plate)?
I'm going to combine some of the thread with one of these:

I'll make some sort of loop thing for threading it through the camera. Pics will be posted
It looks like it is the standard plate thread Dougsters used. I have an identical one. It has 5mm of thread, the plate is about 3mm thick..... Dougster I think you're mad.... You'd be better off just using the plates own hoop or getting a longer centre bolt.
I use the system from http://www.carryspeed.com/
I got it primarily because I was impressed with their attitude of making very sure it cannot come apart.
The plate uses an Allen Key (stored in the plate), so it is way better than finger tight and is very secure.
The strap is secured using a limited movement ball joint so it cannot scratch your camera.
The ball joint is secured to the strap using a mechanism that's new to me (see the video), but is ultra secure and even that is backed up by an O-ring in case you didn't tighten it up properly.
The strap buckles cannot be released single handed, so no worries about it popping open.
So far I've used this system to cover two festivals and I've never found anything slackening or shifting.
And the neoprene strap is SO comfortable!
Edited to add - there is a UK distributor.
The tripod QR plate isn't taking any weight.
It screws onto the L=Plate
Even if it's on the tripod it will only be for macro shots.
Why is that mad??
I wouldn't trust a 60p Karabiner from ebay to hold my camera that's for certain! It hasn't even got a locking screw gate on it, very unwise.
Sorry Doug. I think I got the digression started - I couldn't see the gap between the L plate and the tripod QR plate. They looked flush and so I thought you'd removed the screw that came with the Q-strap and were using the manfrotto screw alone.The tripod QR plate isn't taking any weight.

Thanks for the info, certainly an interesting alternative to my Blackrapid. Who is the UK distributor you bought it from?
It is only an emergency backup! And for that purpose it is plenty strong enough. It is unlikely to remove itself even without the locking gate.
Still wouldn't trust it, even as a backup. For 1% the worth of your camera you could get one that won't remove itself, not unlikely to.
Well the chance of it coming off on any one day is less than 1%. The chance of the main clasp failing on that day is also less than 1%. Combined, that makes the chance of me dropping it less than 0.01%. Or one drop every ten thousand days.
As an engineer I have been taught that a number like that can be considered negligible, especially considering how many other and more likely ways that are for me to drop it.
Well you're not the only engineer circulating this forum and I certainly question your percentages reached without any knowledge of the material strength of the ebay Karabiners other than a photograph of them.
I'll keep a look out for the thread entitled: Well what was the chance of that happening.....![]()

Coin Lock - eek :|Thanks for the link. Does yours have the allen key locking screw or the new coin lock? It looks like they've changed the design from the video.
And they take PayPal too. I just sold my old mobile on eBay so I can see the PayPal balance not making as far as my bank account...
What are they like with longer lenses? I have the sigma 150-500 and normally remove the tripod collar as it gets in the way although I could rotate it round 180 degrees and it seems perfectly balanced like that so I think it would work well.

If the screw fails (unscrews) I was thinking that perhaps a thin but strong cable/wire as a last resort, just something to give you enough time to grab the camera?
