I used 135/2 during last year's trip to Inner Mongolia. But I found that I got some distortions near the lower half of all 135/2 images. Otherwise, it is very sharp & contrasty. I suspect it is my copy of the lens not accurately squared to the sensor plane (ie titled a little bit). This is not noticeable during everyday usage but very objectionable for astro use. Thats why I didn't bring it with me during this Taiwan trip. If your copy does not have this problem, perhaps I should sell mine and get another one...:u_14 :u_14 :u_14
