Canon R5. Comparison of Canon RF 100-500 vs Tamron 150-600 lens.

I compare the Canon 100-500 RF lens to the first generation Tamron 150-600 lens. The canon lens is three times the cost of the Tamron lens; but is the Canon lens three times better than the Tamron? 0:33 Introduction 7:00 Minimum focus distance 7:22 Field test and birds 14:08 Testing static objects with both lenses 18:14 Testing both lenses on a tripod with IS off 20:18 Testing Tamron F 6.3 vs F 8 21:34 Conclusion
