First path was one in search of a new-ish prime lens for the µ43 system. I figured it would be a Lumix 20 or some variant of a 25mm (of which many are available). With the 14mm and the Pentax 40 and 70mm Limiteds in hand, what would be the better fit?
Another path was an old, familiar one: backpacking. I had been contemplating a Sierra trip to a familiar area - well it was so in the mid-90s at least. It was a short hike to pretty country, and a pony ride would be available to carry my wife.. and maybe some nice extra camp comforts? Hmm..
This path led me to reconsider my dear old hiking slides that were wasting away inevitably in a corner of our garage. I'd really like to revisit that trip - but of course the slide projector has been dead for a decade or more. Time to reconsider the task of digitizing the slides?

Convergence occurred - and off I went to look over sale copies of the 35mm f/3.5. I put up a bid and today it worked in my favor. The lens will arrive soon, and for well under $75! Just for old times' sake I looked at the imaging-resource lens tests, and remembered why I bought a copy before. This is an excellent 1:1 macro lens, even more so for such an absurdly low price.
This purchase tells me that the 20mm will be a better future fit than a 25mm lens. It also fits nicely with the nagging thought that I should let the 40mm Limited prime depart with some other Pentax gear. The 70 will remain however!
Time to take another look at those old 1990s Sierra hike slides..
