The 200-500 is actually sharper at 500 than the tammy at 600. As far as weather sealed, I NEVER SHOOT IN THE RAIN. What's the point?
And, I shoot hand help in Florida's Wetlands all morning, why would I shoot with the heavier tammy?
If you check weights you'll find the Tamron is lighter. I shoot a lot of wildlife on horseback and ATVs and.get wet often. Your weather predictions are much better than mine.
