Just thought I would follow up. Ordered mine originally from B&Zhao back on Nov 16, 2022. Finally shipped to me on Jun 2nd, 2023 and got it on the 5th. Only took 6 and a half month to get it. Have got to get out an try it out on my EOS R5. Use to own th EF 135/2L and use it all the time on my 5Dx family. Mistakenly sold it when I switched to Sony because I was concerned about adapting it to FE mount. Bought back into Canon with the EOS R and then R5 but still shooting with Sony as well. Now need to get out and compare it to the Sony FE 135/1.8 GM. The s on the Canon version should give it a step up I hope. We will see. Wish me luck.
