We only use soft ones and they are great, you can fold them back ect. - cheaper too - also have one or two old lenses with the slideout intergrated type and they are great too - some camera shops i visited had like big bins of dozens of old soft lens hoods - and you just fished thru and found ones that fitted the filter thread - some have universal threads. How they apply to the modern camera lense i have yet to find out
