If the security of your digital camera is important to you, I recommend you consider purchasing this strap. Let me make a premise right away, I have always believed that the original shoulder straps are the best ever, but after a bad personal experience I can assure you that this is not always the case... This one from K&F Concept is Delivered in a beautiful premium box in gold and silver. I immediately noticed it because the thickness of 3 cm is plenty and it also allows the length to be adjusted from 100 to 160 cm. With its weight of 130 grams, it can carry up to 36 kilograms, a load that cannot be achieved with any combination of SLR and TELE LENS. I can wear it in three ways: classic on the NECK, DIAGONALLY from the shoulder to the opposite side and directly on the single SHOULDER. The WEBBING is made of 100% nylon with synthetic polymers, it's practically the same material as car seat belts... and I've said it all! The HOOKS are made of METAL, are 3 mm thick and not plastic like conventional shoulder straps. Paired with high quality leather with double stitching. In addition, most of the original shoulder straps cannot be easily removed. So I'll let you imagine how inconvenient it is to attach the SLRs to the tripod (or monopod) every time, so most of the time it's best to leave them hanging on the camera, which is dangling and annoying. This one, on the other hand, has two comfortable BUCKLES that allow it to be opened quickly. They are made of a resistant and unbreakable material, stealth nylon. They are released in 3 steps and with the help of both hands, so you can be more than calm, it is impossible for them to come off accidentally (in my video I tried to pull them repeatedly). And finally, the CABLE that needs to be attached to the camera loops is covered with 3 layers, each of which has its own color. It is always good to check the condition of use and color. The outside is BLACK to indicate the excellent maintenance condition, the second inner layer is YELLOW indicating the risk of breakage and finally the last inside is RED indicating the impending breakage of the shoulder strap. In summary, I can say that the choice of shoulder strap is very personal. It's certainly not cheap, but thanks to the opportunity presented, I can trust you that I had no problem running some stress tests. I PULLED, PULLED and MASSED it in virtually every way before entrusting it to my work SLRs, both combined with two lenses (L-series) of significant weight. I tried it on both the Canon 5D with 24-70 f2.8 and the huge “white” mammoth Canon 1D + 70-200 f2.8. Knowing the models and weights of this device, you can be sure that all MIRRORLES (objective) can be entrusted to this shoulder strap. However, I found a DEFECT... but only if we decide to use the shoulder strap in the classic way, namely on the NECK. Unfortunately, since it doesn't have a soft lining, it can strain your neck after a few minutes, especially if you're using heavy equipment. It is therefore enough to change position frequently and perhaps move it over your shoulder. It's a shame because it cost very little to be the PERFECT SHOULDER BAG for my needs. If you find it at a discount, perhaps with a coupon, it turns out to be a good deal!
