Yes
So,the above has happened for the second time whilst out walking,with the body dropping to the floor,both times luckily onto a grass surface.
Its slung on a Black rapid strap and hangs around pocket height on my right.
I can only assume the release button has somehow been depressed by catching on my wallet,the only thing in the front right pocket,then spun off as I walk.
Has this happened to anyone else?.
No doubt it will happen again and end in tears,is there a fastening to secure it to the black rapid clip or eye?.
 
I always carried my 7D & 7D2 connected to a Sigma 150-600 via a BR strap without any issues. In fact, I used to use the same method on my 300 f4 & 70-200 f2.8. I can only think it's a issue with the lens if it doesn't do it with other lenses.
 
if you're secured to the tripod foot on the lens why not get a tether fixed to the body on the tripod mount or strap mount.

Have you tried to remove lens by hand to see if theres a fault? If you're hitting the release button you need to hang it differently or try a different strap to keep it away from whatever is pressing the lens release.
 
I have 7d2 sigma 150-600 on a blackrapid and I have never had a problem.
 
Release Button ? My BR attaches with a carabiner that has a screw lock. Carried my D500 & 200-500 no issues.
 
I have a 70d and the 100-400 mkii and have not had any problems with my black rapid strap. However I always keep my hand on it just as a precaution.

Release button on the camera that releases the lens. Sounds like the lens is staying attached to the BR strap and only the camera body is dropping to the floor.

There are tethers available that you can attach to the camera to the BR strap. BR do one:

So do Joby:

https://www.amazon.co.uk/Joby-JB01307-PWW-Camera-Tether-Charcoal/dp/B00HVT2D4Y

You could easily fashion one from a piece of para cord and a karabiner.

Have you checked the lens is securely attaching to the camera? Not sure how it works on canon but Nikon need the button depressing and the lens twisting at the same time to start the lens removal process. That’s unlucky if it’s happened twice. Another option available is to put your wallet in your left pocket so it doesn’t catch on that.

I used to carry a 120-300 sport and 5d3 on a BlackRapid and used an Optech Uniloop attached to the strap lug and fixed part of the carabiner swivel just in case.

I think it pays to be on the safe side with expensive camera kit.

If you know it's going to happen again it may be prudent to change the design/manufacturer of the strap.
 
After years of using a BR strap with no problem i have twice lately noticed the carabiner starting to come unscrewed, i can only put it down to my new EM1MK11 being used with a battery grip, the carabiner is rubbing against the grip and it must be starting to unscrew it. So no matter how long any one has happily and safely used one i would say keep checking and looking for new possible problems.

Agree,I thought it was a freak happening the first time.Will now be securing the strap to the body as well.

As above thought this was a one time accident,but will be looking to tether them both to the strap to prevent it occurring again.

Thanks all.

I didn’t think we can blame the strap manufacturer here, any sling strap, be it a Q strap, Black rapid, Kirk or even Peak Design would have the same issue as it’s where the strap is contacting the OPs body. The strap hasn’t failed as such. Th only option is to change the strap back to a neck strap as it wouldn’t catch in the same place that’s causing the issue. There are many others using sling straps without any issues so it’s difficult to blame the strap type because of this one case.

We could blame the camera manufacturers for this one, why isn’t there a locking lever in addition to the release button? It would be easy to include a button locking mechanism to prevent inadvertent/accidental lens release.

Is that the screw on the carabiner? If it is, BR do a safety latch that goes over that to prevent that coming apart unintentionally

Tethering is a good idea to as it would stop the camera dropping to the floor once released, but it’s not going to stop the camera and lens coming apart in the first place. If it is catching on your wallet and releasing the lens put the wallet in be another pocket to stop the unintentional lens release (if that’s the cause).

Is that not what I suggested?
 
When I have my 150-600S on my 7D2, the lens is connected to a Black Rapid strap using the foot connector and I use an Optech Uniloop on the body with a carabiner connecting it to the strap.

See... just more proof Canon should have stuck with the FD lens mount and not caused all the problems swapping to EF :-)
 
Just thought of the obvious solution.
You sling the camera on the BR strap so it's hanging on the right of your body, correct?
With the camera body upside down and lens pointing back, the lens release button is on the left side of the camera body, ie it's closest to your moving leg.

Simple solution. Swap the hanging camera to your left side. This way the lens release button is on the side of the camera furthest from your body.

I use my BR strap this way and have had no problems.

(Obv taking further precautions with tethering the body to the camera also makes sense)
