First my apologies for a lack of info.

I own 35/f2 (most recent model sn#3847462)
         50/f2 (second edition? sn# 2294162)

I live on the Georges River in Sydney. There is a land mass about one (1) - 
one point five (1.5) kilometers away from me.

When I compose and focus with the 35 the landmass +  infinity = sharp in VF.
When I compose and focus with the 50 the landmass +  infinity  = blurred 

In order to produce a crisp image in the VF I must turn the focus ring clock 
wise (so closer to the Ten on my lens). This error occurs even if I look at 
say the OTIS lift building at Hurstville (which is about 5 or more km away.

The Lens itself will not go past the infinity step. However the lens will go 
one click (not a full stop, a quarter ?)  past f16.

My question then (the lens won't go past infinity so no worries). 
Considering the 35 is fine at that distance, should not the 50 also be. Is 
it possible that the RF can work fine for one lens and not another? (this 
does not sound logical to me but......). Is it possible for the markings to 
be incorrect the infinity measurement for feet seems closer to the true 
infinity measure I get than the one for metres. Should they not be the same.

I appreciate everyones help so far. Oh my pictures look sharp but I street 
shoot people from 1.5 metres. I have never taken a landscape with this lens. 
Ever (i just spent ages looking).
