To be fair, one should look at a cost/performance ratio. Olympus designers
were given a rare go ahead to design a slightly wide angle to short telephoto
zoom without optical compromise. And the price shows what it took to
accomplish that. Now is it far to compare that to a used 50 mm f/1.8 that
Paul vT used to sell for $19? As a man of limited means, I've always
considered primes to be my way of producing outstanding image quality at a
price that still allows me to eat and have a shelter.
