I just don't trust that much weight on the connector to the camera.
I don't know why camera manufactures supply lenses in this size and weight category places one can attach straps to as a place to attach shoulder straps.

Both of the wildlife lenses a use have this and I use them regularly




Frankly if the lens start to get around the 4lbs mark and is longer than 1 foot it could be a deciding factor in the purchase of the lens

Great addition; however, most (I would guess) don't have this nifty feature. I could rig up a strap to the foot of the lens; but again, I'm simply careful handling the lens.

I have never liked attaching a strap to a lens via anything attached to the lens foot unless there are 2 point of contact. I have seen to many come loose or break that even when using a swiss adapter on a foot it I use 2 points to anchor

Ian I am trying to imagine using your rig.
Is your kayak like a fighter plane and you have to point the kayak bow at the target. Then you use live view and a bit of elevation in the mount to get the target framed? (I guess you dont practice greenland rolls with the mount installed.)

Having followed this thread over the years in anticipation of this event (like waiting for the other shoe to drop), I'm am sad report the lens barrel separation of my D-FA 150-450. I purchased my lens in July 2016 (serial number 4409156), and up until today, it has performed flawlessly. I had a sense this might be coming, as over the last few months the zoom was getting noticeably looser. I've always treated my lens with kid gloves, and never carried it in the down position with the lens zoomed to 450. So today, as I was zooming, the lens barrel just started to freely rotate. And that was that. Thankfully nothing fell to the ground, so the only damage is the lens barrel separation.


Given that my lens is long out of warranty, and my experience with "Pentax Authorized" repair centers has not been stellar (I have no direct experience with Precision but CRIS managed to not repair another lens twice before finally getting it right, and then it failed again two months out of warranty) I am inclined to go with Phototronic. I will be calling them tomorrow morning.
Another Victim of this stellar lens , sorry to hear of this Dave , i do hope it is repairable given the dollars that are put out for this lens , best regards Alan

I finally got around to sending my D-FA150-450 to Mike at Phototronic.biz per Aslyfox's recommendation. After talking with Mike, I'm confident he can make the repair, or at worst, just make it a fixed 450mm lens.


Also, found out that he is familiar with the aperture block issue that many Pentax cameras suffer, and had a relatively inexpensive repair for that too (he said he doesn't actually replace the solenoid, but has a work around that fixes the issue). So I sent him my aperture blocked K-30 too. Getting everything fixed.

Late comer to the news in this thread, but I would 100% advise against anchoring a strap with all contact bearing on the 150-450 tripod foot.
The photos in this thread give plenty of evidence that the foot is not capable of withstanding excessive force.

I had the same thing happen to my D-FA foot, like @vegasdenny's photos in that thread indicate.
