Thank guys. Appreciate every post.
I sent an email to C.R. Kennedy enquiring about the warranty if purchased from B&H Photo
"We will not honour any warranty from overseas grey imports. Our policy is on our website:

We will still repair and service your camera and charge you."
From C.R. Kennedy
So I end up with Sigma 70mm F2.8 EX DG Marco
