Strange rings on image - Canon 5D IV + Tamron 85mm F1.8 VC lens
« on: December 19, 2016, 12:15:08 PM »
Hello,

I just purchased a Tamron 85 f1.8 DI VC lens for my Canon 5D IV.   The camera has the latest firmware (1.03).   I'm experiencing a type of vignetting with circular rings on the image.    I searched Google and this link is a similar issue except it is a Sigma lens with the same camera.

Is there a fix for this.
 Thanks

Try the "fix" that seemed to work on the sigma lenses:
Setting some or all of these setting to disabled

Quote
When using a SIGMA interchangeable lens for EOS, setting the corrections to [Disable] is recommended, as “Lens Correction” functions of the camera, such as Peripheral illumination correction, Chromatic aberration correction, Diffraction correction and Distortion correction are not supported.*

I had the same isssue with a Sigma Art 35mm 1.4 on.  5D Mk IV

Turning off all of the corrections fixed it
