My thoughts on using the Sigma 135mm 1.8 lens on a Sony A7RII mirrorless camera. I did tell myself last month that I would only purchase native glass for this camera, but since everyone praised about how great it is, I had to find out myself. Purchased from B&H Photo Video Pro Audio, out the door I had an issue with it the MC-11 needed to be updated. The Lens will focus fast under GREAT light but low light it hunts in just when you get the green light to shoot the focus box turns white. I didn’t mind the weight because with the battery grip it balance out.
It’s going BACK ASAP. I’m only buying native GLASS for it !!!!!
