Review on 📷 Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary Lens for Canon EF: Complete Bundle with USB Dock & Essential Accessories by Michael Daniels

This lens offers stunning photography at an affordable price. If you're using a crop sensor camera, you're really getting a 640mm lens for this price. The filters that come with it are rubbish so don't use them. The CP filter caused the images to become blurry, see the above image of it. Don't ruin this lens by using it. Check out the photos with this rating to see how cheap filters affect the lens. To at least get an overview of this lens, check out Fro Knows Photo on YouTube to see a real test.
