請教各Ching,這兩支的picture quality,那一支好,不要理會range的方便度,如大家都以24mm or 40mm的range來比較picture quality

[minipolochun]

我覺得一定係 24-105

如果咁講~~一定有IS O既比較好

I have these two lens & used on 5D2
@24mm, the 17-40 wins (less distortion & sharper)
@40mm, the 24-105 wins (sharper, less CA)

Obi-Wan兄
如用在50D或是500D(即APS-C的機),又如何?

[Obi-Wan]

really not much difference on 50D @24mm & 40mm

[yiu0920]

咁24-105 f/4L用係450D同50D,相片質素分別又如何?

[Obi-Wan]

no much different

[Panda1802]

如是用50D,是否值得把17-40換成24-105?

[Obi-Wan]

No, better buy 55-250 IS

[Panda1802]

Obi-Wan
你的意思是17-40 + 55-250 is better than 24-105

[MrK12345]

24-105 ok 呀
我長期插住部機(500d)

[Obi-Wan]

"你的意思是17-40 + 55-250 is better than 24-105 " YES!

兩支我都試過, 24-105中間sharp d, 但邊位好鬆.

I am looking at 500D body. If I use 500D, mainly to shoot baby/kids indoor/outdoor, and I plan to buy 50mm 1.8 already. Which standard zoom is better? 17-40 + 55-250 or 24-105?

[Obi-Wan]

17-55 IS F2.8
