Hi, I've had a bad habit of buying a lens, then buying a filter or two for that lens, then buying another lens later that wears a different filter size, rinse & repeat. So, I'm (finally) thinking about in the future standardizing on 77mm filters, and just buying a step-up ring for those lenses that aren't 77mm. But it seems like, occasionally, I've read people complaining about problems with this setup... so I thought I'd ask you folks, in your experience... - what has been the drawbacks (if any) to doing this? - are there filters that don't work well with a step-up ring? I figure a neutral density filter shouldn't be affected at all; but I am wondering about polarizers etc. - can you get a hood to work in this setup? Thanks for any help or guidance you can provide!
