I've recently acquired a Canon EF 28-300mm f/3.5-5.6 L IS USM zoom lens which I have mounted on my 5DIII with battery pack. The combined weight is more than I feel comfortable with hanging off my neck alone, so I want to buy a shoulder strap, which would have the added bonus of keeping the camera handy at my side, while leaving both hands free when I'm not using it. I've seen two straps which might work: Manfrotto Pro Light Camera Strap and any of a number of straps from Blackrapid. The Manfrotto strap utilises the camera lugs, so nice and secure. However, the Blackrapid appears to entrust the entire camera+lens assembly to the tripod mounting point. My initial thought is: Really? How secure would that be? However, I thought I'd ask on here for any opinions or even suggestions for alternative shoulder straps. I don't want the full pro type, where there are twin shoulder straps and a linking chest piece .. I'm only a keen amateur! However, whatever I do buy must have a nice thick comfortable pad where the strap lies on the shoulder.
