Review on Sigma 150 600Mm 5 6 3 Contemporary Canon by Rob Jimenez

I bought this for my Canon 80D for more range than I got with my 70-300L for wildlife. At home I put it on a tripod and compared the pixels with a Canon lens and found that I got just slightly more clarity at 600mm than at 300mm with Canon when zooming in on images 15 feet away. Even on my heavy Benro tripod, I found the weight of the lens very sensitive, even if I touched my foot to the ground, and it was very difficult for me to focus manually as the slightest touch in Live View would change the entire frame made to vibrate. In the field, I found that the only benefit was having a tripod and time to carefully zoom in and focus on a distant animal. But it was useless to hold the hand of flying birds and the like. I rarely get a clear picture. The picture quality was very good. Sometimes the autofocus didn't work at all. I guess because it was far out of focus it was freezing. But he acted like he hadn't even tried, he just froze. I'd have to either find something else to autofocus or manually focus to get it out of lock. Occasionally. Other than that, focusing works well in most cases. It's heavy and well built and I had no problem walking around my neck with it on and I think the weight will help stabilize during arms. keep. With the right tripod/head and in good light this would be a great lens for wildlife if you don't already have a quality 300/400mm lens that is worth the price. But only in good light, like my 300L Crop Sensor. If I were to go with this lens I would consider a gimbal style tripod head or something sturdy enough to take sharp shots at 400mm+. Love the smooth yet firm focus and the zoom rings and lock button to keep the zoom anywhere you want.
