I've always wanted a long Canon lens for wildlife, and I'm about to give myself a big Christmas present this year. In deciding between the 500mm II and the 600mm III, I had been leaning to the 600mm III. The 500mm seems easier to carry and haul around by all accounts, but I often read about a preference for more reach. As I often have my 300mm II with the 2x TC attached, I know what that feels like.

Accordingly, I've been leaning to paying the substantial additional money for the 600mm III.

Then I saw this comparison at The Digital Picture Review, which has generally provided me with accurate comparisons of lens IQ:

As you can see, the 600mm II is a bit better at the center than than new 600mm III:

In fact, the old 600mm II is very slightly better at the center with the 1.4X TC attached than the 600mm III is bare:

Adding the 1.4x TC to both lenses makes the 600mm III look ridiculously, unusably poor by comparison:

https://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=748&Camera=979&Sample=0&FLI=1&API=1&LensComp=1227&CameraComp=979&SampleComp=0&FLIComp=1&APIComp=0

Have users who have "upgraded" from the 600mm II to the III been disappointed by the new lens, particularly with the 1.4x or 2x TC attached?

If real-life results of adding the 1.4X TC to the old 600mm II really left the new, bare lens in the dust as these tests imply, I would pay more for the old lens, weight and all. If, on the other hand, the new lens is comparable to the IQ of the old one, I'd gladly pay up for the weight reduction.

I would appreciate feedback from those who have used/compared both lenses, or links to similar tests that would confirm or refute the tests I linked above.

I am separately weighing the differences to the 500mm II, but I am interested in whether the 600mm III is the right alternative, or whether that lens has so compromised IQ for weight savings that the prior version would make more sense for me. For example, if the old 600mm II is truly better at 840mm than the new lens is bare, or if the new 600mm III at 840mm is as bad as the review above makes it appear, I would easily opt for the old 600mm II lens.

Thank you. Joseph


Joseph I have used both 600 II and 600 III with and without TC's, after extensive use its hard to call on image quality. But i sure enjoy the weight reduction for hand-holding. Comparison images below, bare 600 III and 600 II x 1.4.
