The Canon RF 100-300 2.8 As A Wildlife Lens

Time and time again, it has been stated on the the internet that the Canon RF 100-300 2.8 is not a wildlife lens.  I have used this lens extensively in Churchill, Yellowstone, India and Uganda.   Soon I will be taking the 100-300 2.8 on my Katmai, Alaska Coastal Brown Bear trip along with the Canon RF 600 f/4.  It will be interesting to see which lens is used more in the environment Katma offers.  The Canon RF 100-300 2.8 is maybe Canon's most versitile lens especially with the way it can take the RF 1.4x and RF 2x teleconverter.  There is virtually no image quality loss with the 1.4x and even with the Canon RF 2x teleconverter, you will still have tons of keepers of fantastic images.     

 

Many are waiting for the mythical 200-500 f/4 that is the supposed replacement for the Canon EF 200-400 f/4 TC, I have to wonder with the versatility of the Canon RF 100-300mm 2.8, is this is the replacement not only for the EF 300mm 2.8 but also the EF 200-400 f/4 TC.  The 100-300 2.8 is one of Canon's sharpest lenses.

 

Below are three sets of galleries with the RF 100-300 2.8 with and without the Canon teleconverters. You can decide for yourself!
