Need help diagnosing one-sided vignetting on Leica M262
Camera: Leica M262
Lenses: Voigtländer Nokton 40mm f/1.4 Classic, Nokton 35mm f/1.5 Vintage
No filters or lens hoods used.
I’m seeing strong, asymmetric vignetting only on the M262. The same lenses do not show this behavior on my M10 or M11.
Behavior:
-Most severe wide open (< f/2.0)
-Not shutter-speed dependent (seen from 1/2000–1/4000)
-Occurs only outdoors, never indoors
-Strongest in bright sun, but also present under partial overcast -Always affects the bottom of the sensor
-Flips position when the camera is turned upside down
-Independent of sun position (front, back, or side)
Key finding:
Creating a very deep makeshift lens hood completely eliminates the one-sided vignetting.
This seems body-specific, orientation-dependent, and light-related. Any ideas whether this points to a shutter issue, sensor shading, or internal reflection specific to the M262?
