Review on 📷 Sigma 150-600mm Contemporary Lens Bundle for Canon DSLR with USB Dock & 2x 64GB SD Cards by Charles Baker

I could not get clear photos with a Sigma 150-600 mounted on a Canon EOS T2i. I originally intended to use the lens to document bald eagle nest sightings. I've relied on the Canon 75-300 in the past with some success, but was hoping the Sigma 150-600 would produce more detailed images, especially when spring rolls roll in when foliage makes it harder to get a good shot. The "reviews" I read before buying the lens praised the merits of the autofocus capabilities. It didn't work for me at a distance. I tried combinations from fully automatic to manual. I tried to reproduce the ISO, shutter speed and aperture settings of successful shots taken with the Canon 75-300 from the same angle and subject. I've tried the lens with and without a tripod and monopod. I tried triggering the shutter manually and remotely. I tried to photograph a dogwood in front of the house, tested autofocus with matrix, image stabilization, focus settings, etc. There are no plates. Finally, at 11:30 am on a sunny day, I was sitting about 70 feet from the birdhouses in my backyard, alternating between Canon 75-300 and Sigma 150-600, autofocusing on the same subjects. Canon produced sharper images. I gave up. Sent the camera back to the seller. I didn't have the original packaging material and they refunded $802 of the $939 purchase price.
