Great, but...

This really is a great lens for its evenness of performance and general optical (and mechanical) properties.
Unfortunately it does have one potentially very obvious optical weakness when used on full-frame, and that is...linear distortion. Perhaps I've been spoiled by years of shooting on crop formats, but wow...I was surprised just how obvious it was in the horizons of my seascapes, particularly at 70mm.

Re: Great, but...

this is a great canon lens, and probably the most underrated! i had mine for many years and my companion on my overseas trips, but unfortunately, i lost it! i have taken some of my most memorable shots with this lens, but then i replaced it with canon 100400 II for its reach and versatility. i am contemplating to get a copy of rev.2 of this lens for travel for being so light and small.

you mean it's not perfect?  i'm afraid no lens can with stand the rectal exam of the lens tester.  I shoot landscapes and I use this lens a lot and love it.

I don't think the Kent coast is a rectal exam, but each to his own! 
I loved this lens when I used it on crop sensor bodies a decade ago. I still love it on full frame; I just had a bit of a reaction to seeing the sort of bendy horizons I once got on the first cheap zooms I used back in the 1980s.

It is still a zoom lens and may have more distortion than a good prime lens. I can’t recall ever being bothered by this, but maybe the horizon line on the California coast is not as flat as in Kent? Lol.

hmm...do you have any photo ro share with us, which demonstrates that "bend" you are speaking of, please?

This is very easy to fix, either in DPP or Lightroom using the automatic lens profile corrections.
