Yes sir you are correct there. I have stated many times I do not like or use that site very often but some lab measurements can be telling. I am comparing the newest versions of each lens. That is what I have in my hands and what I actually use. I use them primarily on my 1Ds Mk III. That is the camera I use to judge my conclusions on. Since my retirement I have probably bought and sold three dozen lenses. But in this case, the Siggy and the Canon I have kept. I will never sell the Canon. It is that good. I have about six or seven lenses that have found a permanent home.
If you are a fan of 'that site' did you read their conclusion .....
"Even though the competition still beats the Sigma 70-200mm across the board (as noted above), when we compare the newer version versus the older version of the same Sigma lens, ..."
BTW, if you want the best third party 70-200mm f2.8 it is without a bit of doubt the Tamron version that is labeled A009. Not there first atempt of a 70-200. This is not any web sites opinion. That is mine, with hands on use.
My original statement was
. . . since Canon's release of DLO, I wish I had spent the extra money on Canon lenses. While there is little difference between lenses like the EF 70-200 f/2.8 (original) and the Sigma 70-200 f/2.8 HSM without DLO, when DLO is applied there is a noticeable improvement for the EF lenses. That degree of improvement just isn't there when using Adobe products.
If I were starting over knowing what I know now, I would have stuck with Canon lenses, and forgone the third party lenses.
I was specifically talking about a lens purchase decision I made. And how Canon's release of Digital Lens Optimizer would have changed my decision process if I were to do it again. At the time in the mid to late 2000's there didn't seem to be a reason to spend the extra money on the Canon version, the Sigma version was just as good on MY camera, better according to another popular digital photography review site.
Yes, Canon's second generation IS L lenses are unparalleled. And, even Canon's consumer STM lens of today hold up very well when compared to older L lenses and third party lenses. But, that fact completely misses the point I was making.
