I am new to using filter, so I would like to get suggestions from others. I am used to having lens hood to prevent flare which especially useful with older lenses. Now that I am venturing out to use filter and try to standardize to the largest lens diameter. That means I need to use step up ring. My question is, if I am using a smaller lens with step up ring, how can I still use the hood? Do I need to get a universal hood for the filter size? Thank you in advance.
