Hoya lenses used to get great reviews in some of the photo magazines, some were good others were right dogs. They gained such an indifferent name and disappeared. Of course the plant contiued making lenses but the designs and build quality were changed and they were sold under a different brand name.
I bought a new 28mm Hoya WA, wonderfully sharp but so prone to flare it wasn't practical to use on a bright sunny day. In fact the only realistic & honest magazine review said just that but came out 2 or 3 months after my purchase.
Hoya had the potential to have been up alongside the Vivitar S1 and Tamron SP ranges but they didn't make it and in fact lagged behing Vivitar & Tamron's cheaper ranges in overall quality acrooss their range of lenses.
