I have bought EF50/1.4 from him. Initially, it did not focus properly with my 20D, and talked with him. Then he has set up for a repair at the Canon Service Center. He paid for the repair, sent me a shipping label, and the lens came back re-calibrated.
Now the lens works very well on my 20D.
Thank you very much and I really like the lens now!!
