Didn't PK put TTL metering first in an affordable cam?

TTL, Pentax LX=1980, Olympus OM2 =1975

Yes Pentax was first again.

The Spotmatic, introduced in 1964, was the first Pentax SLR with TTL metering and one of the earliest SLRs of any manufacturer with that feature.  (This is not the same as TTL flash metering, nor is it automatic exposure.  Nevertheless, it is through-the-lens metering, and was a significant development.)

Notably , the LX has OTF metering , which continues to meter and allows for changes in exposure DURING the exposure .

This feature continued at least in the *istD which also has the exposure sensor in front which measures light reflected off the film/sensor when the mirror is up .

I have used this to good effect in my LX's , which are capable of metered exposures down to 125 seconds , and will modify these exposures if the lighting changes during .

As touched on , it also governs TTL flash exposures , another thing the *istD keeps in common with the LX .
