Granted, technically there's over 30 years and tons of differences between the two cameras, so an actual comparison would be rather silly, but still. The Olympus was a *miracle* of compactness when it was made, and that included the lenses. (It's still a remarkable and beautiful camera.)
The Fuji, because of today's fantastic small sensors, has at least comparable quality (I'd say it beats the O in many ways, plus a ton of features), and it jacket-pocketable. Its zoom, granted, has slightly smaller reach (120mm (equivalent) vs 150mm), but then it goes much, much wider (28mm vs 75mm), and it's way faster (F:2.0 to 2,8 vs F:4.0).
(If I'd had an F:2.8 zoom from back then, it'd have been twice the size and heft of this Olympus lens.)
The Fuji lens is shown in its folded-up size, and the Olympus lens is shown at its shortest setting, though it looks like it's zoomed out.
Wait, I do have a full frame F:2.8 zoom to show. OK, it's a bit longer still, 80mm-200mm, but just look at that beast! And it's not even an old lens.
The Nikon with lens is 2.3 kilograms! The Fuji is 360 grams. (Five pounds vs 0.8 pounds.)
(By the way, that Nikon lens cost over three times as much as the whole Fuji camera, but when they started making full-frame cameras, it turned out the corner quality was really poor, so they had to replace it fast.)
Like I said, I know that these are not really comparable sets of gear, this was just for fun.
If I'd put the Canon S90 (or S95 or S100) on the left, it'd be even smaller yet (breast-pocketable), and have a not-dissimilar quality, though the handling of course suffers on such a tiny camera.
UPDATE: Russ says:
Olympus has been making high quality, pocketable cameras for decades. My favorite is the XA model. It has a wonderful 35mm 2.8 lens. However, I think the best feature is the almost inaudible shutter. Makes for great stealthy street photography. Even though most are now over 30 years old, you can still find good working examples on eBay for relatively little money.
Yes, the XA and similar film-cameras like the Minox 35, the Rollei 35, or the Konica Big Mini, are amazing.
Though in order to be this compact, they are confined to a 35mm lens, probably F:2.8 or less. This can be all right, and I have owned and several of such cameras*, they are highly useful and I love them.
But if one want's a zoom, it gets a lot bigger if one keeps the large film/sensor size. And if one doesn't, on film the quality suffers badly. This has been the issue, and personally I find that the Fujifilm X10 is so far the best compromise I have seen in these matters, brought about by advances in lens and sensor quality.
*My first film super-compact was a Ricoh with a gate design like the Minox, I loved it. But it's apparently lost in the tides in history, I can't even find a photo of one, boohoo. Wish I'd kept it. A couple of my more successful pictures were taken with it, this one for example. This one was also taken with such a compact, though I forget which, I only had it briefly.
UPDATE: Okay, I just had to include the Canon S90 too, for completeness's sake. Outstanding camera, for a real pocketcamera. (28mm - 105mm zoom.)
