I got into photography with a Pentax K1000 and a 50/1.7 lens. This was in about 1984. My dad had had a Praktica and I had borrowed a Nikon FE from a friend at some point before that, but the K1000 was really my first real camera. Its main attraction was that it was inexpensive compared to many of the other "entry level" cameras. I was so new to photography that I didn't even know you could buy a used camera. When I went to "upgrade" in about 1989, the LX was the natural choice because I could keep all of my lenses. I loved both of those cameras as much as I loved photography, so my appraisal of them is fully, completely, utterly clouded by sentiment. My memory is that at the time Pentax had a wide variety of lenses, but that Nikons generally had a deeper bench (e.g. a 28/2.8 and a 28/2) and that there were more fast Nikkors than Pentaxes (e.g. the Pentax 35/1.4 was essentially un-ownable). The Pentax winders didn't have as much oomph as their Nikon counterparts either.
I was working at a small newspaper in a country with no Pentax distributor when the rewind crank fell off my LX. After a couple of weeks of needing a needle-nose pliers to open the camera in various closets and darkrooms, I traded in all my Pentax gear for a Nikon F4 and 50/1.4 and mostly never looked back. (I did buy another LX years later, and then sold it off again --crazy).
Now I have one thread-mount body and about a dozen lenses, all of which were picked up at ridiculously low prices. The 35/2, 50/1.4, and 85/1.9 are particular favorites. The new trend in mirrorless cameras allows all of these lenses to be used on digital bodies and I can think of no better lenses at these prices, except maybe the Konica Hexar AR lenses.
