Sigma 100-400mm f/5-6.3 DG DN OS Contemporary (L-mount)
This Sigma 100-400mm Contemporary is the lightweight L-mount reach zoom for wildlife and sports, weighing just 1135g with a 67mm filter thread, optical stabilization, and full-frame coverage. As an enthusiast pick it's a travel-friendly telephoto, far lighter than 150-600 class glass. It's for shooters who value packability and OS; pass if you need 600mm of reach or fast f-stops in low light, since it tops out at f/5-6.3.
