Late convert. Blackrapid rs5. Did an all day event for company ... Used with 17-55 & 70-200 f/2.8 ml 2, 7d sometimes with 580ex2. Bye bye kata, lowepro & crumpler.:thumbsup:
i use proloop optech strap for my 50D+grip+24-70 with total weight 2.5KG(no kidding), but with this strap i didn't feel any pain or after pain even wearing it from 11:00am - 18:00pm walking around with my kit in universal studio, it's also a quick release detacheable strap so u can remove it before putting into ur dry cabi
