I'd tested my fren's 17-55.. while f2.8 and IS are cool... the build doesn't convince me to pay that much for it. sorry. The zooming itself doesn't have the friction of an L like my 24-105... not to mention weather sealing. (I know pple will say I don't have a weather seal body... but weather seal will help keep off some dust than the non-Weather sealed lens)
I will choose 16-35L.. and I am not waiting for mk2 cos' it is a 82mm filter.. I like 77mm filter.. which I can share CPL filter.. since I already have 3x 77mm lens :lovegrin: And I agree with you.. MKII will be very much more expensive.. the current 1st version is already super in its class :thumbsup:
haiz.....i think i will wait and see, hope the EFS 17-55 IS price drop again lol. seldom see people sell this efs 17-55 IS. Now can see many selling his 16-35 L, 16-35 MK2 is calling them lol
