Here is the link to Fred Mirandas first impressions. Here is the link to the Final Thoughts:
“This past week, I had a great time pushing the Sony FE 135/1.8 GM lens to the limit. Overall, Sony has once again delivered a top resolution lens, without neglecting rendering. In my opinion, the FE 135/1.8 GM is easily the best medium telephoto prime on the market today.”
