Tamron SP 150-600mm F/5-6.3 Di VC USD G2 Telephoto Zoom Lens for Canon DSLR Cameras - Perfect for Wildlife, Sports, and Nature Photography

Full disclosure, I returned the lens. Now for the review.This is a really good lens, I was impressed with the focusing, the sharpness at 600mm, and the quality of the pictures I took. It’s well balanced, optical stabilization is good.So, why did I return it? It was too much lens for me. It was too heavy. I bought the lens in preparation for a trip to Africa next year. I decided on this lens because of the features. I figured at nearly 4.5 pounds that it shouldn’t be an issue. I brought it down with me to Florida for a weekend, and lugging it around a wetlands down there told me it was a major issue. I like to handhold, this lens was very difficult to do so. Also found it difficult to pan with a moving object.In reality, you need a monopole to steady it. All in all, it was not the lens for me. But, for those looking for a lens in this range, I highly recommend it. It is a quality lens that does it job extremely well. That is why I give it five stars despite my experience with it.
