[Leica] Leica lenses on Fuji X Pro 1 Vs Sony A7

Thu Jan 26 07:31:50 PST 2017

You are looking directly at the image sensor output.  If focus shifting (
the change of focus plane with change of aperture) is a consideration, then
check your focus again AFTER you set taking aperture and make final SMALL
adjustments.
There are only a few lenses that focus shifting is a consideration..... the
35 Lux FLE ( first version ) is one of them. Other lenses were not designed
to have this problem and therefore do not worry using them.... ( 50 LUX
ASPH)

I should mention that even with a Digi-Leica camera body, focus shifting is
an issue.  It is inherent in the specific lens design.  There is no camera
body based fix possible.  With a EVF,  you have the ability to correct
it....  
Using more DOF ( smaller aperture) will help mask this error source.
Your other choice is to not use focus shifting lenses.....  or suffer trying
to get really sharp focus on your subject by focusing initially at shooting
aperture, which will be frustrating, especially at F32 ( for example).

At F1.0 a Nocti is easy to set at precise focus using my technique. The
correct focus plane POPS into focus.  Trying this at smaller aperture, the
focus plane can be found, but it is not as obvious nor does it POP into
focus.
This is all a lot of verbiage.  If you try it with a real camera and lens,
you will find how easy and accurately it works.  

This method is slooooooow.  It is however, more accurate than the Digi-M you
might be using, or your AF Nikon, Canon or Leica SL  body in AF or MF mode.

AND when your M9 camera breaks on day 8 of your 42 day trip to Canada, it is
a photographic life saver. 

Do you want to use it on every shot you ever take in the future?  Including
your 3 year old grandkids who move like whirlwinds?  Probably not the right
tool.
