The 28mm f2.8 Hoya lens is brilliant, very sharp and contrasty, however don't let the sun within 180 of the film plane as the flare is horrific. Worst I've ever seen with any lens and that includes a Sigma 24mm Wide angle The magazines gave the lenses great reviews (as they were taking advertising revenue), the public voted with their feet and the brand was up graded & relauunched as Kiron.
