Not so much continuity of philosophy, I think...Olympus has a philosophy, while Pentax just does it anyway.
I got my Oly XA from a bloke in Canada.
Really, that is a gem of a camera, a real work of art. How they went to great lengths to put a great lens in it and yet keep it tiny - rather than compromise on both size and cost, Oly put a genius, fast (f2.8!) 35mm in there, made from high-refraction and low-dispersion elements, not just plain old optical glass. How the aperture is controlled by a vertical slider, how it's switched on a beautiful sliding dustcover (the lens was designed to accomodate this feature, and the cover was a must to keep the lines of the camera clean). How both ends of the viewfinder are cover by this cover.
And the lens ain't that bad at all (gets a little weird at f2.8) Ilford FP4+ at 50 ISO, so it's pretty sharp anyway. But still...
Little things like that. How the self timer switch is a little foot that swings out to stabilise the camera on a table - I've never used that feature, but it's the most impressive thing for me. Really, that bit's genius - when are you going to use the self timer on this camera? For self portraits - this is a party camera, a social camera - when you're sitting around with friends. It's not like you're gonna be lugging around a tripod when you're using the XA. It's for sticking in a coat pocket or a handbag.
And did I mention it's the size of a twenty-pack of durries, yet still has a built-in rangefinder? Yep. Smallest rangefinder in the world (will get to small cameras in a moment).
And to top it all off, the finish of this plastic camera is made to feel like
stone, something classically Japanese, and beautifully tactile.
Thing's so small I keep the A11 flash on it just to make it easier to use.
Like Nesster, I do wonder what Olympus were thinking (smoking?) during the nineties. I haven't heard much - unlike Canon or Pentax or Nikon, whose workings in the AF 35mm era are easy to stumble upon.
If there were any manual-focus SLR cameras I'd turn for, it'd be the single-digit OM series. They're small, solidly built, and easy to find decent lenses for. From what I hear, the only difference between a pro-grade OM lens and a consumer-grade one was their maximum aperture - ie, the same build, glass and formula went into the f1.8 50mm as the f1.4 50mm. Plus spot metering on the OM2s, of course (do they all take mercury batteries, though?)
My favourite Pentax at the moment would have to be the ME Supers. Cheap, easy to find, but oh what a camera. If Pentax ever needs to do any thinking about how to build a viewfinder for the next DSLR, they should stop - all they need to do is make one exactly like the ME series' VFs. It's not that it's big (easy to do) it's that it's
bright. It really is like looking through a window. An open window, to boot. Not to mention LED shutter-speed display and fast metering.
It also makes me wonder why people claim that Leicas are "compact". If you ever get the chance, stick an ME next to an M6 or M7 or MP and gaze upon how the Leica dwarfs the ME. Even including the mirror box, the ME is so much smaller. Also, an ME can do macro and telephoto.
About the only thing that's annoying about the ME Super are the buttons to change the shutter speed. If you can work them while still looking through the VF and without tripping the shutter, you're more dextrous than I.
