Range finder accuracy

I have two M cameras, a 10-P and a 262. Both seem to show the identical "inaccuracy" when I focus on a distant object (in this case a wind turbine about 1km distant) in that when both lenses on each camera reach the stop at infinity, the distant vertical appears to cross the ghost image leaving the ghost image to the right. Since both cameras appear to be behaving identically, I am suspicious that it may be more about 'user error' and my eye sight! Can anyone suggest an explanation or an alternative means of checking whether camera and lens are correctly set up? Thank you in advance.

I'd suggest starting with taking photographs and comparing the results of the distant object both at infinity stop and where your images coincide. If your vision has recently been tested and you are wearing eyeglasses and/or contact lenses...are the prescriptions up to date? Progressive lenses are a source of frustration for many photographers. Another question... are you using the same lens on both bodies when you experience the issue you described...the lens itself might need recalibration. Since you observe the same issue on both cameras, it is unlikely, in my experience, that the cameras are out of calibration. Good luck getting the issue resolved...it can be a source of needling frustration. I check my mostly used lenses and (film) bodies each year...I find that occasionally I need to touch up by a hair the horizontal alignment at infinity with the change of season....I think it might be temperature related.

Thank you for your reply spydrxx. I have used different lenses with similar results on both cameras and like you say, it is unlikely both cameras are out of calibration. I wear glasses for reading only and find they are totally unusable with the viewfinder. I will try and follow your suggestion on taking photographs at both the infinity stop and where the images coincide but this could be tricky because the movement required is so very little. I would appreciate it if you could expand on and explain what you mean by "touch up by a hair the horizontal alignment at infinity..."

Thank you once again.

2 mm hex key in the roller on the arm inside the camera mouth. Minuscule adjustments. Check on the LCD. Use an object at "infinity", say at least I km away.

Thanks jaapv. Will do.

All Leica officially calibrated M and lenses show this very character. They allow the lens to focus slightly beyond infinity. I tested this on all lenses new or old, lens or body, at official Leica store.

As long as the images came out perfectly in focus, you shouldn't worry, and I'm not worried a single bit.
