I'm an ultrawide junky and make no apologies for it. As much as I love my 14-24, there are times when it's just too big to cart around with me. There's also the filter "issue" with it. The 16-35 is tempting, but it's a bit more than I want to spend right now. So, that brings me a round to the 18-35 as a possibly promising option at well under $300 from KEH. It would be used on FF digital(D800) and film. From what I can gather in some reviews: 1. It's light and plasticy(not a bad thing given why I'm buying it) 2. It has a lot of distortion With that said, it has an aperture ring. I know that will make some(many) of you roll your eyes, but that's a selling point to me since it gives me full compatibility with "key" bodies(F2AS, FM2N, FA, F4). Also, again I love the 14-24 but its showing its limitations to me as a film lens due to the lack of filtration(no colored filters for B&W or warming filters for slides). In fact, I've considered buying a 14mm 2.8 precisely so that I can use rear gels. So, with all of that in mind, how does the old 18-35 hold up on something like a D800?
