Default My comparison of Canon & Tamron's 24-70 2.8

I didn't want this to get buried in the main Tamron 24-70 thread, so here's a new thread. This review focuses on the sharpness (including edges) and IQ of both lenses. Other reviews have already gone into the Tamron's other virtues so I didn't feel a need to go there.

If I made any mistakes in testing, kindly let me know.

Thanks for the review. The Tamron seems impressive and this seems to agree with the lensrental tests as well.

I too thank you for the review. Looking more and more like the Tamron. Just when?

Nice work, could you add the same resolution tests for 35mm & 50mm focal lengths ?

Great job. Would it be possible to evaluate with the new Canon 24-70 L Mk II.

Very Interesting ...
But note the problem with any apple compared to any other apple is the population of one compared to population of one.
Soft lenes exist with any brand
but your test seems to agree with the majority of tests.
Would like to see flair tests and focus speeds.

True about the odd apple, which is why I'd like to see other users do a similar test with this chart to see if the results hold up over a wide range of copies.

Done! Scroll down to the "35mm & 50mm Tests" portion that I've just added.

Sure, as soon as it's released I'll try and get my hands on it.

Thanks for the review. I own the 28-75 and never had the urge to get the Canon equivalent. IS is not important to me in this focal range. I would love to see a comparison between the 28-75 and this newer 24-70, as far as IQ.

Thank you for the review. Considering it's a comparison of a 10+ year old lens versus one that just got released, I would hope the Tamron would win with all the technological advancements that have been made. lol.

Hopefully you can continue this review with the new 24-70 II and see how it stacks up.
