My daughters and I use Google Photo... works fine.
I just bought the Tamron 70-200 f/2.8 a few weeks ago. So far, so good. I really like it. I take a fair amount of sports pictures for the grandkids and it has performed great. The only warning is that it is heavy! I use a sling strap and that helps. I would not want it hanging around my neck for any length of time.
