I just received my “new” refurbished EF-S 17-55 f2.8 from Canon.
Really excited, until I began testing the lens and comparing it to my 18-55 kit lens.
The 17-55 is touted as being a great lens, please tell me if the one I got is merely lousy
or if this is typical.
I've done a bunch of boring tests, but here are some comparisons of the 17-55 compared to the kit lens at f5.6.
The 17-55 is sharper in the center.
The 17-55 has less CAs
The kit lens is sharper with less distortion on the edges at all focal lengths.
Is this a bad copy? If so I'll see if Canon will exchange it.
What is other people's experience?
