Mine is the Sigma 300 F4 APO/Macro; rather than the DA.

Yes, I've been using their products for many, many years, as they are only 90 miles away.

Other people have solved this problem with a sling strap attached to the tripod socket of the lens's tripod foot. Black Rapid and other companies manufacture such a set-up. However, the gear has to be firmly screwed into the tripod socket so it doesn't come unscrewed, resulting in the lens/camera combo crashing to the floor. This also leaves the tripod socket unavailable. Also, Black Rapid's set-up costs about twice as much as OP/TECH USA's gear.
It is possible to attach to the tripod foot and still have the tripod socket available...see the pic below.
Re coming unscrewed, the 'trick' is to put a small spot of Loctite 277 on the thread and you can be sure it will only become unscrewed when you actually do it yourself!

Cheers,
Terry

yes there is a bit of wiggle from side to side
I just love technical talk...

That said it might just be down to fair wear and tear and over time with big heavy glass this happens.

It happens in other brands too I'm sure.

Is this the 150-450 lens tripod foot or another lens ?
That sure looks solid and safe though.

Indeed, technical vocabulary has always been my forte at school !

I wouldn't think that "wear and tear" should be a cause here, unless there is a factory defect with a lens that is less than 1 year old ! Then again, who knows?

Reviving this thread ....

My daughter decided to switch system for a Nikon D750 and (whatever lens she will use with that ???) and she is going to send it to me and see what goes on with it ... she hasn't yet sent it out for "repairs" (if needed).
Now, I am wondering if this is worth my while to get it sent here and "see what happens" ? In any case, it will likely be listed for sale (perhaps on the MarketPlace here) if she ever decides to sell it quickly.

Your thoughts on that?
Thanks!
Edit : lens she will use: Sigma 150-600 Contemporary

I couldn't help wondering whether the five little tiny screws that hold the mounting plate on the back of the plastic internal lens body haven't wiggled loose a bit?

I am not sure whether those tiny screws have something to do with the loose connection; all I know is that she will send it (lens) for repair, apparently direct to Ricoh Canada?? I thought this was not available anymore ...

Thanks Steve.
I'll let her know.
She is presently in Belize doing some bird "banding" with a group of biologists.
