[Leica] Leica 24-90 SL lens question

[Aram Langhans]

Tina and anyone else with this new camera.  I have a question.  Does this lens have a hard stop at infinity or does it focus past infinity in manual mode?  I am thinking of night astrophotography.  My35-70/4 has a hard focus at infinity.  I just turn till it stops and I am all set, no matter what focal length I am using.  Not so on my Nikon AF lenses.  Not sure it this is the way a lens has to be designed for AF, or if it is just cheaper to do so.  

Also, in manual focus,  if you focus on an object at 90mm, does the focus change as you zoom out to 24?  In other words, does the focus change as you move through the zoom range?  Again, the 35-70/4 does not change focus as you zoom, but all my Nikon zooms do.  The 16-36/4, the 24-120/4 and the 70-200/4.  The worst offender is the 24-120.  My love to hate lens. Again, I am thinking of astrophotography.  If the 24-90 SL lens does not have a hard infinity,  I would like to be able to focus once on a star then not have to refocus if you change the focal length.  Hard infinity would be best, but this would also work after the initial focusing.

I looked at the review by Dowling.  I really need to stop looking.  It really makes me want one  in spite of the size.  It looks like a very impressive camera with a great viewfinder, the thing I really dislike about the other mirrorless cameras.  But I know I should not spend that much money, if I had it, and just enjoy what I have now for a while.

Thanks.
