On this quick video photographer Tony Northrup and his wife Chelsea compare two popular zoom telephoto lenses from Canon – the EF 100-400mm f/4.5-5.6L IS II USM and the EF 70-200mm f/2.8L IS II USM with the Canon 2X III teleconverter to see which performs better.
If you are looking for a (relatively) inexpensive long telephoto lens – this quick comparison betwen the two Canon lenses (plus the converter) is worth watching, however we do suggest that you keep in mind our notes below.
Now we do have a few caveats about this comparison. Even if the second sharpens test is correct, Tony mentioned nothing about AF performance with the 2X converter which can be a real deal breaker. Another thing which Tony din’t mention is that if you are specifically looking for a 400mm lens – Canon actually has a better, lower cost option – at least if zoom isn’t necessary for you – the Canon EF 400mm f/5.6L USM (which does lack image stabilization but otherwise is a great, sharp inexpensive and light long telephoto lens).
As for pricing:
