I´m intending to buy the 165 LS lens for handhold portraiture and the like and would like to know, if it suffers from mirror/shutter vibration at, like, 1/60 or 1/125 sec. Theoretically it shouldn´t, because the big shutter is not used and can made to go up for 1/8 sec. or longer.

It is my opinion that you could shoot the 165 LS with the focal plane shutter in use and still get acceptable shots at 1/125 sec. If I can shoot the 150 Takumar at 1/30 sec and get most shots to turn out, then the 165LS should do OK with the focal plane shutter. The 165LS with the leaf shutter being used, 1/30 sec should easily be possible. SR

Before you buy beware that the 160LS does not support independent leaf shutter like the 90LS. What this means is that not only will you still be using the camera shutter when using the leaf shutter but you will not be able to use mirror lockup when using the leaf shutter. Buy this lens only if you need the high flash sync. It will do nothing to improve shutter/mirror vibration. For that you need the 90LS. Otherwise it is a very fine lens. By the way the 160LS goes down to 1/60 not 1/30 like the 90LS.
