I tried it with a 135/2.5 and a 35/2.0 on my *istD, both at f4. As I suspected, it was much easier to focus the 135. Finding critical focus on that lens was easy. The 35 appeared to be "in focus" at a wide range of settings. Finding critical focus was more difficult. But I already knew that. I've been doing it for more than 40 years.
