Hi everybody,
I am a proud owner of the Tamron 24-70 VC which I use on the Canon EOS 6d.
During developing of my Holiday photos, I have discovered that some of the photos Show significant shadows in the Corners / vignetting, but mostly in the right side of the picture.
All those photos had in common that they had a rather small aperture (6.3-9) and were shot towards the tele end of this lens (60-70mm).
My - and probably everybody's - first guess would be a badly fitting Hood or a UV Filter... but the Problem isnt solved by removing those.
Wide angle photos, even with bigger apertures, look fine and don't show asymmetrical vignetting.
What could be the reason? Do i have a decentered lens? Can it be caused by the Image Stabilisation?
And why is it worse in Tele than in Wide Angle?
Unfortunately the weather is so bad here that I don't have the sky and light conditions to try to reproduce the Situation until now..
Looking Forward to your Input
