I used a Black Rapid sling, it attached to the tripod lug. I was uncomfortable with the weight of the body and heavy and expensive lens being carried by the tripod lug. Optech is 1 less expensive and 2 attaches to the strap lugs. MUCH better AND frees up the tripod lug for its intended purpose.
cheers
I agree. I have an optech single and I trust my camera on it...it's not going to break and it hangs just right on my hip.
