The market and supply and demand decides the selling prices, and in the final analysis you have two choices, either pay the price you consider ridiculous or do without the item.
Don't you believe in Santa any more then?
On this 'fast lens vs slow lens' debate, lens performance is not always a factor in selecting one over the other. All my Zuikos are the slower lenses because I value compact size and lighter weight and, as a bonus, all have the same 49mm filter size. Whatever we decide all choices invlove compromises and trade offs. Sometimes the littlest thing makes a big difference. On my OM-1 bodies I leave off the hot shoe, it is amazing what a preceptual difference that makes in the feel of the camera even though it is a very small part.
About the 40mm f2. I've had 3 pass through my hands, all purchased for much less than the then current adverage price. The last one I bought several years ago for $200 and sold for $600. That lens is just too valueable to be a user. All my Zuikos would be rated BGN or UG by KEH but work fine.
In regard to OM-1 vs M body size. I've had OM-1 for 40 years and when I finally got an M4-2 in 2010 I was surprised at how small the OM was sitting back to back with the Leica, only the mirror box makes it thicker and the prism peak is barely 1/2 inch higher.
Frankly, I haven't gone shopping OM lenses lately and my stable is the most basic lineup: 50 1.8 MiJ, 28 3.5 and 135 3.5. Very happy with all of them.
HAve taken a quick bay look and I recall them being lower.
Nowadays with great fast films (thinking Portra) not such a concern, but sometimes that extra stop would be very useful.
As of the OM-1 size, it's still a quite remarkable one. I got an EPL2 with kit zoom, micro 4/3 which was deemed a nice format for minaturization... But the size of both is quite equal! So much for "progress". The same can be said about many AF 35mm SLRs however.
About the digital SLR...what a monster!
It almost dwarfs my medium format SLR!
Re fast v slow debate, I like fast lenses, but having said that, I think the 3.5 Elmar is one of the best lenses ever made.
On a trip my dad was surprised when he lifted my OM kit. 28+50+135+body. "This thing weighs nothing".
Out of the forum scope, but almost no one nowadays put a 35mm sized sensor into a smallish camera! The 4/3 (and later m4/3) was marketed as an ideal size and for being smaller than the other formats. Now manufacturers seem to seek smaller size, but not on 35mm; Seems like it's quite hard to do... Perhaps it's something they will unleash some day for increasing sales.
At first I didn't see the OMs as THAT small, but having compared I see they are!
I think since there is so much praise for the Zuiko optics on so many various forums across both film and digital formats the prices for these lenses will only go up. I track ebay daily for certain lenses that I want, Zuikos included and for the past year havent bought a single one. The prices have been quite high compared to a number of deals I was able to snag 2 or 3 years before. I am happy that I have my main shooting kit set, 28mm f2, 50mm 1.4, 85mm f2 on a few OM4Ts. I would recommend others to look for 3rd party lenses, as they are actually quite good as well. I have a 19mm-35mm f3.5-4.5 vivitar series 1 and a 35mm-70mm f2.8 tokina atx zoom lens that perform great for the price. I also have a Komine 24mm f2 which also performs very well.
