hmmm I just had a leaf through some old Camera magazines from 1980. In the back there are private "classifieds", amongst which I found a OM Zuiko 85mm f/2 for sale for 120.

A quick scan of recent eBay "sold" items (worldwide) for that lens shows the most expensive at around 350, the least expensive about 100.

Using one of the online "inflation calculators", I found that a price of 120 in 1980 equates to the best part of 440 today.

The magazines also featured some nice pictures of flowers, and some of the pro photographers appeared to be over 40 ...
