Funny you mention this so recently... I came to the forum just now after mentioning in a PM to another member that I keep seeing OM Systems marketing all over the place. I couldn't help but take the bait a couple of times in the past 2 or so months and have a look (not in person, just video review, the site etc.). I've become rather agnostic but the reality still lies in the investments one makes in glass and such; many are content to send all they have to KEH or post a fire-sale pricing ad... and then begin again. Sometimes multiple times. I can't do it. Too much hassle. I'd rather just be shooting.
Anyhow I figured someone around here must have mused about OM a bit in this regard...
Other than my Ricoh GRs, I just don't shoot digital hardly at all for quite some years now (since early 2014 now that I think about it) but I've been shooting a Nikon Z7 when I do - but that was prompted by a want to use my Konica glass on digital, as well as a big fat sensor for better film scans. And I've not been able to let go of my K3, for no other reason than I adore the DA*300 and it for occasional birding (I may let it go yet still, but haven't been able to so far). Anyhow, circling back to OM Systems.... It really strikes me that this is the direction Pentax should have been going for quite some time. They long ago left their compact functionality (a slot now filled by Fujifilm) and moved toward a more rugged shooter. Seems like they could have really capitalized in that vein, combining both aesthetics somehow. A rugged, weather sealed, but compact and agile utilitarian shooter along the OM lines, but full frame (obvious cannot be
as compact/nimble in that case, but Sonys are tiny and there are some Ricoh design cues to draw on as well) and mirrorless. I'd be paying a lot of attention. At the end of the day that's largely what the K1 and K3III are in many ways... I just wish I could combine the two.
(And frankly, even after two months, as much as I've enjoyed the increased resolution in my scans as well using those Hexanons digitally that the Z7 allows for... I just am still pulling my hair out over the Nikon menu systems and layouts. I yell at that camera as often as I praise it.)
