This Pentax camera arrived four years late and was missing the feature it was literally named after…yet it sold in the millions

Pentax Spotmatic.

When the prototype Pentax Spotmatic was first shown at the 1960 Photokina trade fair in Germany, it was the first SLR to promise both through-the-lens (TTL) metering and the first with spot metering.

But by the time the Spotmatic reached the market, almost half a decade later in 1964, the Topcon RE-Super had beat it to the market with TTL metering by a year – and despite its name, the spot metering was missing!
