Hello guys, I found that my lecia m4 RF alignment need to adjust. 
However, when I want to screw the biggest bolt in the mount, I found that I can't screw it.
 
It totally fixed. 
I google a lot of article, but I don't find anyone else has same problem like me.
AS a result I come here to ask you guys; is there anyone had same problem like me?8

Hello, I want to share with you my last experience with the SL.
It was the first studio session on location I had, mixing strobes and ambient light, since I purchased the SL. During this session I have had a really hard times trying to focus on some faces during this group & portrait session yesterday!
I was in a white walls area and the ambient light was rather normal (sunny day). I was shooting with a moderate natural and clear back-light coming from 2 windows. I used 2 strobes on the persons. Most of the time, I was more or less able to focus easily, but on one face it was almost impossible, wherever I set the focus point on the sensor, to focus! I had to add a side continuous light to be able to focus. And even so it was not obvious to achieve it right all the time.😳
To be honest, I am a little disappointed by the "lack of power" of the AF response. Even my previous DSLR (Nikon D800 & Pentax K1....) were better in low or contrasted lights than the SL. 🤔
On a more positive side the image quality (especially skin tons) is far better than everything I had in hands before. 🤩
Has anyone gone through such difficulties and is there a better camera setting to insure better results? Many thanks in advance for your educated advice.  😁

Hi there,
I brought myself finally a Leica Q last week. Its a really nice camera, but I have one issue I dont know if its a bug or a settings problem:
If I half press the release button, the camera is focusing. I hold the button half pressed down until my subject is ready for the picture. If I press the button fully down (without releasing it), I assume the camera is taking the picure, but what it does is its focusing again and the taking the picture. I have set the mode switch to "S" and AF Mode to "1 point".
Setting the Zoom button to "AEL/AFL" does not work either. Pressing or holding the button does nothing! With settings to Zoom the button works as expected.
A reset of the camera settings did not help.
Am I doing something wrong?
Kind regards,
  Sebastian

I had my camera and all lenses calibrated for back focus issue by Leica NJ 2 months ago.  I thought everything was good until now I just realized the patch at infinity isn't completely aligned on my 35mm Summilux.  Thanks to a newly acquired 1.4x diopter.  I see double lines with tiny space in between when I point at construction grids at infinity.  My 90mm APO doesn't have that.  It is sort of minute, am I being too picky?
