This may or may not be a tall order!
I've been trolling the www trying to find a site that lists/shows the history of Pentax 35mm SLR's in a format that would say whether each model is/was considered amatuer/entry level, advanced amatuer/intermediate level, and Pro level.
The only site I could find was this one:
...but to be honest, I didn't find it to be put together all that well, and it really didn't give the info I sought as far as the user level I desired. I noted those that were mentioned as "Consumer" models, but what does that really mean. We are all consumers in my way of thought, amatuer or pro.
Can anyone point me to where I might find the info I seek?
So far, this is all I can come up with, on the Pro level (I only went back to 1980):
1980 = LX
1991 = PZ-1
1994 = PZ-1P
2001 = MZ-S
2003 = *ist
