p.2 #5 · Canon 24-70mm f/2.8L II reviewed by Photozone | |
Hah and what do you know, if you ignore the extreme measurements, again these are far corners where the eye tends to not look so much, but focus on his border measurements which cover extreme centered L and R edges and even heading down to the corner, i.e. the edge areas that matter for most photos then this beast does do VERY well and it does score even a touch higher out at the edges than the 24 1.4 II.
Border scores 24mm f/4 and f/8:
24-70 II - 3128 and 3175; 1.12 and 0.86
24 1.4 II - 3172 and 3104; 0.91 and 0.82
24 T&S II - 2917 (f/3.5) and 3053; 0.41 (f/3.5) and 0.43
16-35 2.8 II - 2945 and 2882; 1.02 and 0.92 (26mm)
24-70 I - 2879 and 3060; 0.89 and 0.69
24-105 - 2797 and 2891; 1.72 and 1.4
tamron 24-70 - 2921 and 2997; 0.73 and 0.74
17-40 4 - 2830/2856 and 2998/3027; 1.2/0.64 and 0.87/0.34 (20mm/28mm)
samyang 24 1.4 - 2874 and 2952; 0.70 and 0.64
zeiss 21 - 3002 and 3006; 0.79 and 0.70
zeiss 25 2.8 - 2245 and 2777; 0.68 and 0.66
zeiss 25 2 - 3150 and 3274; 0.32 and 0.20 (whoa!!!!!!! holy cow this one scores off the charts on all #s whoa)
crazy in the center, no distortion, zero CA, good grief man)
tamron 28-75 - 2622 and 2866; 1.87 and 1.84 (28mm) (i have to say that mine was sharper at the edges than any 24-105 I've tried so I guess copy variation?)
so at or near 24mm the clear winner is the zeiss 25 2 prime with no af and next best score is from the 24-70 II (at f/8) and 24 1.4 II (at f/4)! for border sharpness
of course there is also distortion, CA of both forms, large scale contrast, various types of micro-contrast scales, field curvature, ability to T&S and so on and more than just the above numbers (he says the new 24-70 II has a lot less field curvature than the 24-70 I)
zeiss 25 2 the best for CA with the 24 T&S II also very good there and the 24-105 the real stinker for that
i think the 24-104 and tamron 24-70 were the worst for distortion from what I recall
zeiss 25 2.8 by far worst border sharpness and then 24-105 next worst
for kicks I add center frame 24mm f/4 and f/8:
24-70 II - 3732 and 3580
24 1.4 II - 3849 and 3494
24 T&S II - 3740 (f/3.5) and 3543
16-35 2.8 II - 3436 and 3340 (26mm)
24-70 I - 3240 and 3386
24-105 - 3216 and 3309
tamron 24-70 - 3556 and 3346
17-40 4 - 3310/3172 and 3292/3225 (20mm/28mm)
samyang 24 1.4 - 3740 and 3409
zeiss 21 - 3561 and 3235
zeiss 25 2.8 - 3514 and 3278
zeiss 25 2 - 3740 and 3548
tamron 28-75 - 3387 and 3255
for f/4 center sharpness the 24 1.4 II has crazy scores and does best but 24 T&S II and 24-70 II and zeiss 25 2 and samyang 24 1.4 also do really well
for f/4 center sharpness the 24-105 and 24-70 I do worst
for f/8 center sharpess the 24-70 II does best and the 24 T&S II and zeiss 25 2 also do really well and the 24 1.4 II not bad
so the 24-70 II is actually at or near the tops against all of these at 24mm f/4 and f/8 center and edge other than for CA where it is unfortunately middle of the road and is the top zoom
i guess not so suprising the 24-105 comes out worst overall (other than the tamron 28-75 which does not match the copy I have)
the zeiss 25 2 is just sick
