I purchased this lens for my 5D MIII primarily for events, weddings, architecture, etc. I was hesitant to purchase an off brand lens, but Sigma has really stepped up their game in the past couple of years! For $600, I figured it was worth a shot, and boy was I right! If you are looking to invest in a good fisheye lens, this is it.
