Yes, definitely. It's really not even a fair fight, between the 16 and the 17TS-E. The 17 TS-E corners are still tack sharp, unlike the 16-35 which turns to mush the larger the aperture you go.
Don't get me wrong, I love my 16-35, but it's really not a fair fight between the two. Each have their own strengths. My main reasons for keeping the 16-35 is it's all-around usefulness (it's a swiss army knife type lens for me) and it handles flaring and bright light sources better than any other lens I've tried. Two things that the 17TS-E does not do well with AT ALL!
Huh? I disagree with the flaring on the 17. It actually controls it much better imo. And you can clean it up easily in post.
17 TS flare.
16-35 II flare.
