Yeah and he even says the tamron is as good on the wide end, but really? His numbers don't say that and his samples sure do not. Just compare the 24mm samples of the building take with both and look at how much crisper the trees on the left and building edge on the right look with the canon (granted who knows how he focused those).
And look at this, just as the MTF charts predicted more or less (the extreme corner is worse than expected but that doesn't matter so much really, so I ignore his extreme numners, far bits of each corner, not THAT big of a deal, it's the center, mid-frame and extreme side edges that matter most):
For f/8 24mm center/border/CA:
24-70 II - 3580 and 3175 and 0.86
24 1.4 II - 3494 and 3104 and 0.82
24 T&S II - 3543 and 3053 and 0.43
16-35 II - 3340 and 2882 and 0.92 (26mm)
24-70 I - 3386 and 3060 and 0.69
24-105 - 3309 and 2891 and 1.4
Tamron 24-70 - 3346 and 2997 and 0.74
17-40 - 3292/3225 and 2998/3027 and 0.87/0.34 (20mm/28mm)
Samyang 24 - 3409 and 2952 and 0.64
Zeiss 21 - 3235 and 3006 and 0.70
Zeiss 25 2.8 - 3278 and 2777 and 0.66
Zeiss 25 2 - 3548 and 3274 and 0.20
Tamron 28-75 - 3255 and 2866 and 1.84 (28mm)
My Tamron 28-75 is better than his for sure, he must have a bum copy.
Man that Zeiss 25 2 whoaaaa.
But that 24-70 II sure looks good though, no?
As expected looking at 24mm, f/4 and f/8, center, edge and CA and distortion the 24-105 basically comes in last of everything. The 24-70 II comes in best of the zooms and even better than primes at times.
