Bah, I have one on order and was planning on using it with my 5Dm3 as a good street photo setup (so you can just have a simple top loaded bag).

I seriously hope it's a lot better than the 24-105, what's the point otherwise? I would rather go with a prime in that case -.-

I've been looking forward to the new 24-70mm II lens for a LONG time... it was supposed to be better than the 100mm Macro and the 24mm TS-E II in all the data Canon released.

I just got to the-digital-picture.com and saw their new review posted.

What a let down.

Not only is it nowhere near as good as the theoretical data says, if you look at both copies they still have extremely serious copy variation and there's little improvement overall. The lens has significantly less reach than the old version and is closer to a 2.6x zoom than a 2.9x zoom like the old version and has a much larger front element too so big improvements are to be expected considering the compromises.

Anyways. I'm wondering if these results are a fluke and if Bryan just got two bad copies of the lens?

Here's my comparison which shows almost no overall increase in quality:

vs old lens (@ f/2.8):

Key: Better/Worse = Slightly better/worse, Much Better/Worse = Much Better/Worse

Note if I don't list which copy it is, this holds true for both copies.

24mm:

center: Better

Mid Frame: Worse sagittal resolution, better meridonial resolution

edge: Better

28mm:

Center: Better

Mid Frame Copy 1: Better

Mid Frame Copy 2: Better sagittal resolution, worse meridonial resolution

Edge Copy 1: Worse sagittal resolution, better meridonial resolution

Edge Copy 2: Much Worse

35mm:

Center: Better

Mid Frame Copy 1: Better

Mid Frame Copy 2: Better sagittal resolution, worse meridonial resolution

Edge Copy 1: Equal

Edge Copy 2: Much Worse

50mm:

Center: Equal

Mid Frame Copy 1: Better

Mid Frame Copy 2: Better

Edge Copy 1: Worse sagittal resolution, better meridonial resolution

Edge Copy 2: Much Worse

70mm:

Center: Equal

Mid Frame Copy 1: Equal

Mid Frame Copy 2: Better

Edge Copy 1: Better sagittal resolution, worse meridonial resolution

Edge Copy 2: Better

Conclusion:

(formula is +1 per copy that: shows better -1 for worse -1.5 for better +1.5 for much better)

Total score. Only 9.5 out of 30. Meaning that overall, less than a third of the frame is improved slightly. You'd barely be able to notice the difference.

vs 24-105mm (@ f/4.0)

24mm

Center: Equal

Mid Frame Copy 1: Much Better

Mid Frame Copy 2: Much Better

Edge Copy 1: Much Better

Edge Copy 2: Much Better

28mm

Center: Equal

Mid Frame Copy 1: Much Better

Mid Frame Copy 2: Better

Edge Copy 1: Better

Edge Copy 2: Equal

35mm

Center: Equal

Mid Frame Copy 1: Equal sagittal resolution, better meridonial resolution

Mid Frame Copy 2: Much Worse

Edge Copy 1: Equal

Edge Copy 2: Much Worse

50mm

Center: Equal

Mid Frame Copy 1: Equal

Mid Frame Copy 2: Worse

Edge Copy 1: Much Worse

Edge Copy 2: Much Worse

70mm

Center: Equal

Mid Frame Copy 1: Equal sagittal resolution, better meridonial resolution

Mid Frame Copy 2: Better sagittal resolution, equal meridonial resolution

Edge Copy 1: Better sagittal resolution, equal meridonial resolution

Edge Copy 2: Much Worse

Conclusion:

(formula is +1 per copy that: shows better -1 for worse -1.5 for better +1.5 for much better (+0.5 per partial improvement)

Total score. 0 ZERO between these two copies and the 24-105mm it's equal.

Here's another comparison that another website did though showing that the new lens is light years ahead of anything else and delivers the expected results:

That's a comparison between f/2.8 on the left and f/4.0 on the right.

What gives? Do we have another 24-70mm from Canon with extreme copy variation?

The theoretical data, and various reviews and comparisons are all over the place.
