Hi all!
OK this is strange, My mom just bought a 6d. and coming from a 7d she really liked the Tamron 18-270mm mark I and was disapointed that she couldn't use it on the 6d as its an APS-C lens. So I was looking at it today and saw that the mount indicator was red. Which, in the canon world, means its a full frame lens. So i take the lens and pop it on the 6d. Im thinking that i must have missed something and that it really is a full frame lens. But than I look through the viewfinder, and the image is compleatly warped and vignetted. so I look on Tamron's web site and it is indeed a APS-c lens. I then tried the Tamron 60mm f/2 macro which is also an APS-c lens and it looked perfect. So my question is why is there an EF mount on a lens that is designed for an APS-c camera when there is a EF-s mount that would limit it to only APS-c cameras? Is this a Tamron thing? And why does the 60mm Macro look fine while the 18-270 looks terrible? is it that its a prime vs. a superzoom?
Has anyone else had this experience?
