I agree with drsnoopy on this 100%, I have owned both Sigma and Tamron ef 100-400's and there is only one reason to buy one, "Moisture-Resistant". Notice its not listed as proof just resistant. Meaning if gets water inside there will be no help

The RF 100-400 is about half the weight. To use the Ram or Sig on an RF body you will need the adapter adding 1"and 100g.

One more thing to add is the RF 100-400 works perfect with the Canon rf 1.4x. The rf 1.4X is quantum over the Kenko1.4 and 2.0. So to use an 1.4x on the Tam you need the adapter and extender.

Yes I know he has already bought the Tam.

This post is for people still looking and may read this.

Disappointing about the Tamron, I was hoping there would be an alternative to the small apertures on the RF.
