If you don't mind the risk with the mirror (which hasn't ever caused actual damage that I've heard), the DX 1.7 is still a good choice. It is also possible my 1.4 is just bad -- it does have a wobble. But it gets sharp quickly when stopped down -- but at 1.4 yuck.

Never tried any of the DS series. The 1.7 DSM is pretty good. Wish I could remember if the 1.4 DSM was.
Quote: I often see the pentacon but didn't even tried it... (what are its advantages for these other lenses? i supposed its the bokeh because i heard it's not that sharp wide-open?
It does have swirly bokeh when wide open, which you may or may not like. And although it is true it is not particularly sharp wide-open, it is practically aberration-free wide-open (or stopped down, for that matter) so it is still useable. It is not horribly soft or anything -- it has a unique look that works for some subjects and styles, but doesn't work for others. I like it. Stop it down and it is quite sharp. One thing I like about the German lenses is the edge-to-edge evenness in sharpness even if they don't always reach the center sharpness of the Japanese lenses. (Judging on an APS-C sensor, so can't speak for the edges you'd get on a full-frame.)
