It definitely, people having issues with the connector breaking is because they put the connector directly to the camera without a ring, the tiny metal loop on the camera is sharps and after little use will cut through the connector, you must use the strap rings that came with the camera.

I would say yes. It holds my Fuji XT1 with a 35mm (50mm equiv) lens just fine. I did use the thicker mounting straps (the ones that tie to the camera) instead of the thinner string type. Just a personal preference. I'm believe that both types of mounting straps are rated strong enough to my set up but the thicker ones just gi me feels bit more confident. The strap is nice too. Not too thick, yet not too skinny either. A comfortable fit for me. Enough length to carry it long or short (I'm 6 ft tall).

I have a Canon 80D with an 18-55 kit lens. Although the camera came with a wider strap, I'm much happier with the DSPTCH standard strap; it's strong, but not bulky. I purchased the (Black Camo) design. It comes with two attachments, one set for lighter equipment and one set for heavier equipment. Hope this helps in your decision.
