If you care about the safety of your digital camera, then I recommend you consider purchasing this shoulder strap.
Let me start by saying that I have always thought that original shoulder straps are the best, but after a bad personal experience I can assure you that this is not always the case...

This one from K&F Concept comes in a beautiful Premium box, gold and silver in color. It immediately struck me for its THICKNESS of a good 3 cm, as well as allowing for an ADJUSTMENT of the length from 100 to 160 cm.
With its weight of 130 grams, it can support up to 36 kilograms, a load impossible to reach with any combination of SLR and TELEPHOTO LENS.

I can wear it in 3 ways: the classic one on the NECK, DIAGONAL from the shoulder to the opposite side and directly on the single SHOULDER.

The STRAP is made of 100% nylon with synthetic polymers, it is practically the same material as car seat belts... and I've said it all!

The HOOKS are made of METAL, 3 mm thick, and not plastic like those of the standard shoulder straps. Coupled with quality leather with double stitching.

Furthermore, most of the original shoulder straps cannot be easily unhooked, so you can imagine the inconvenience every time I have to attach the reflex to the tripod (or monopod), so much so that most of the time, it is better to leave them attached to the camera, dangling and annoying.
This one, on the other hand, has two comfortable BUCKLES that allow quick release. They are made of a resistant and unbreakable material, Stealth nylon. They can be unhooked in 3 steps and with the help of both hands, so you can rest assured, it is impossible for them to come off accidentally (in my video I tried to tug on it repeatedly).

And finally, the CORD that must be attached to the camera loops, is covered with 3 layers, each with its own color. It is always a good idea to check the state of wear and the color of the same. The outside is BLACK, to indicate the excellent state of maintenance, the second internal layer is YELLOW, which signals the risk of breakage and finally the last internal layer is RED, which indicates the imminent breakage of the shoulder strap.

In CONCLUSION I can say that the choice of the shoulder strap is very personal, this one certainly does not cost little, but thanks to the opportunity granted, I can confide that I had no problems in carrying out some stress tests. I practically JERKED, PULLED and MALTREATED it in every way, before entrusting it with my work REFLEX cameras, both combined with two lenses (L series) of considerable weight.
I tried it both on the Canon 5D with 24-70 f2.8, and on the mammoth Canon 1D + 70-200 f2.8 ""white"".
If you know the models and weights of these equipment, you can rest assured that any MIRRORLES (plus lens) can be entrusted to this shoulder strap.

I did find a DEFECT though... but only if we decide to use the shoulder strap in the classic way, that is, on the NECK. Unfortunately, since it doesn't have a soft lining, after a few minutes it could weigh on the neck, especially if you use heavy equipment.
So you just need to change position often, maybe moving it to the shoulder.
Too bad, because it really took very little to be the PERFECT SHOULDER STRAP for my needs.

If you find it on sale, maybe with a coupon, it turns out to be a good deal!
