Hmm Not sure about this item,
Verified Purchase(What is this?)
This review is from: Sigma 18-200mm f/3.5-6.3 11 DC OS HSM Lens for Canon (Electronics)
Tested this on several camera's and I must say the aperture is very slow even at f3.5 and images were darker than they should of been. Item returned for a full refund as there are better lens for the same price or even cheaper.
