It is a nice hood except do not buy this if you have the 18-200mm lens with the 72mm filter size. It will not fit those lenses.
This lens hood fits the new Sigma 18-250 lens that has the 62mm filter size. It does not fit the year-old Sigma 18-250 that has the 72mm filter size.
It is good but not for a 72mm filter size
The lens hood came quickly and was an exact fit for my Sigma 18-200 zoom. Great company.
Fast shipping, fits right and works fine. Excellent seller.
Needed product to replace broken one. This one didn't fit lens. This was the only hood offered for this Sigma. Returned and still waiting for a response .
In order to fit the camera & lens in my bag with another camera & lens, I turn the lens hoods around until needed. The 1st one went over a cliff, the 2nd rolled down the river bank into the water. So hopefully this one will stay with me. The lock position/click could be a little stiffer to keep from bumping it loose so it could fall off. Other than that it fits perfectly.
It did not fit my 24-70 sigma lens like it says it should... "freakin" frustrating..
This hood does NOT fit the 24-70. It is several millimeters too small.
