Review on 📸 Sigma 18-35mm F1.8 Art DC HSM Lens for Canon DSLR Cameras + Sigma USB Dock: Altura Photo Advanced Accessory and Travel Bundle by Johnathan Stoner

Price 👍🏾Quality 👍🏾The only downside is that I had to calibrate the lens for proper autofocus. So that's something to keep in mind. This is a very annoying and lengthy process. I did it myself for the first time. You can also take it to a camera shop or to Sigma. All in all an amazing lens that can't wait to start shooting. FYI, I would suggest taking photos before you start calibrating your lens to see if you have an autofocus issue. So why should I. I also indicated the difference before calibration (black and gray cat) and after calibration (white cat).
