The back story -
I ride a motorcycle RTW and have limited space for camera gear, really limited. I saw that Tamron just came out with a 18-400 lens, but not for sony emount!
So the question is this, I have a Sony 18-200 lens already as my go to lens for all round grab and go shots, from my tank bag. To extend the cameras range what would you do, keeping in mind I can't double up on lens. Add a 2x converter from Sony to increase my range - OR - get a Canon to Sony converter to be able to use the new Tamron Glass?
