In my camera bag, there are two lenses I use the most and it all comes down to what I am shooting that decides which of the two I am using. For a majority of my event coverages, I pull out my standard zoom lens as my go-to weapon of choice. Occasionally, I do find myself yearning for extra reach, especially when I am stuck at a certain distance and can’t walk any closer to the subjects. Looking for a telephoto lens, I tested out the Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary telephoto lens, aka the “light-bazooka,” which is considered highly compact and lightweight to the other contenders on the market. This lens sounds like the perfect fit for me.
