The thing I wasn't happy with on the 17-50 was the smoothness of the zoom.
Thanks for your response.
Hadn't heard about that issue before. Disliked the 18-50 the only try I tried it, but the 17-50 gets better reviews. Wish there we're other affordable options. When I get a chance I'll head down to RED to take the the 17-50 for a spin.
Maybe look into Leica too. Is yours parfocal?
I've only used Cooke a few times, & they had a lovely soft, yet sharp, look. Did you buy a matched set?
Lots of my work involves travel, & hoping my EOS glass might serve double duty, pre-purchased a Birger mount awhile ago, but time's wasting.
