Are these comparable lenses in terms of build and image quality, or is one noticeably better than the other?

Are these comparable lenses in terms of build and image quality, or is one noticeably better than the other?
I would assume so, given the crop factor, 28-135 on full frame is equal to about 17-85 on a 1.6x crop body.
From what I have seen, build quality is consistent between both lenses.
However, I hope someone who has owned both can tell you about image quality.
Good Luck

They cover completely different angles of view, so I don't think it really makes much sense to compare them. To illustrate:
The 17-85 on a cropper is equivalent to 28-135 f/5.6-9 on full frame.
The 28-135 on a cropper is equivalent to 45-216 f/5.6-9 on full frame.
28-135 is very different from 45-216.
In any case, if you compare the parts where they overlap (28-85), the 17-85 beats the 28-135 by a wide margin in contrast and resolution.
