Thank you Tronhard, that makes perfect sense. I enjoy the utility of theTamron 28-300 as I'm mostly outdoors full sun. But...the get the best out of the camera plainly there's a good reason to use the Canon lenes. I really appreciate that insight...
I don’t see the red like for more the a couple seconds using Canon lenses. But it seem the Tamron 28-300 zoom lens flumuxes some of the features. The light flashes for a couple minutes when using the Tamron. Normal?
