Nice shots, Shadowfox! One of my earliest cameras was a Petri Half-7 which had a 28mm zone-focus lens with three or four symbols for guidance. Selenium meter around the glass in the lens barrel like the regular Petri 7s. It was loaned and lost, and I replaced it with an Olympus Pen D2 like the one above. Great little camera, just right to take along on motorcycle trips. Don't have that one any more either.
But I do have two Olympus Pen FT and one Pen FV SLR with a selection of lenses and a M42 mount adapter. Fun rigs to use and with surprisingly nice results, especially nowadays with the improved films.
Just recently I was getting myself worked up over a Pen D3 I found available, but sanity overcame me. Small camera, pocketable, what have I got, I thought... Olympus 35RC, not much larger than the Pen, for one. Canon Elph Jr (APS film, fixed 26mm) for another, even smaller.
And half-frame processing is a pain... not the developing itself but the subsequent printing or scanning. Most labs just can't handle it gracefully.
The more I considered the more I thought about why I like medium format results better than 35mm output, and ended up in RFF Classifieds buying a Fuji "Texas Leica". Not pocketable of course, but... it assuaged the GAS attack. 🙂
