I’m looking to add a super telephoto lens to my gear bag for an upcoming safari, and wanted to get some feedback from the forum on lens choices. I shoot with a Canon 5D Mark IV and have narrowed it down to 3 options: 1. Canon 100-400mm f/4.5-5.6L IS II 2. Tamron SP 150-600mm F/5-6.3 G2 3. Sigma 150-600mm 5-6.3 Contemporary Any advice, personal experience folks have with these lenses, or the necessary focal length range for shooting wildlife in Africa would be greatly appreciated. Cheers!
