It's been a long time since I've photographed any subject that didn't 
have a background.  I suppose if I was photographing birds on 
powerlines with a clear blue sky I might have to hunt a bit.  I take 
photos at least 5 days a week and after doing so for quite a while I 
don't think about which way to turn the lens let alone study it. 

I'm a new M-user and I have to think about which way to turn the lens.  
If you point a m camera rangefinder at a door knob the double image is 
equal in brightness.  You then have to decide whether to turn the left 
or right.  The obvious solution is to not choose the doorknob as your 
point of focus.  If I photograph something with an M camera with 
repeating lines and shapes, I have to think about whether the matched 
rangefinder patch it is the correct point of focus or not.  They are a 
number of situations where focusing an M is harder than focusing an SLR 
and a few vice- versa.   

For what it's worth
