Because the LX has horizontal traveled shutter curtains which limit its flash sync speed. All cameras with this type of shutter only have about the same max sync speed. How many cameras with vertical bladed shutter that also have mirror lock up. There are a few but not many as it difficult to make that type of shutter completely light tight and most depend on the mirror to help.

I am very surprised to see that they didn't use the same shutter in the LX. The K2 is a rugged, long-lived camera which stays accurate for years, flash sync is 1/125. Mine has had no attention beyond new light seals and a good clean, I did take the top plate off to press a dent out and get the hotshoe level again but everything underneath was pristine.
I'd like an LX, but aside from its legendary metering abilities in Av mode I'm not seeing anything to make me find the £200 or so to buy one and the £100 or so for a proper CLA. I already have a K2, a couple of KXs and four MXs. As it stands I'm more inclined to spend a bit less on a nice K2 DMD, which has a few upgrades over the original and can use a winder (if you can find one...)
Interestingly it seems that the K2's metering can also handle exposures of over 8 seconds in Av. I was finishing off the last couple of frames of a roll last week and tried some night shots. Rough timing with my watch suggested that it was happily producing exposures in the 20-30 second range. The batteries are sound and it has proven accurate on several previous rolls. I'll know whether it worked when the slides come back in a week or two. I know the M series bodies with a later version of the same shutter (not the MX which uses a cloth and springs shutter) can do this too, or at least some of them can.
Obviously we can't change anything now but if looked at in the proper perspective at the time of it's release, the reliable/proven titanium horizontal shutters - pioneered by the F then the F2, was the choice in design for all the PRO interchangeable viewfinder cameras of the time. It won't burn even if mirror is locked up and pointing to the sun. Probably due to NASA requirements at the time? In the EOS 1VHS manual there is a caution stating, "During mirror lockup, do not point the camera lens at the sun. The sun’s heat can scorch and damage the shutter curtains."
Interestingly enough the oldest design - XK released in 1972, had the fastest sync speed of the group.
- XK 1/100
- F-1 1/90
- F3 1/80
- F2 1/80
- LX 1/75
- F 1/60
You'll notice that Nikon didn't even raise the sync speed from the F2 to F3 release.
Back in the 80s I lusted after an LX but I never bought one. I did, however, buy an FA-1 finder from a store I worked at in Atlanta thinking I would buy one piecemeal but I never got around to it. Finally, in 2010 I saw one on Ebay without the FA-1 finder and thought I'd try it out. I got it, put the finder on it and sent it to Eric Hendrickson because of some minor issues. I liked it a lot, but the one thing that bothered me a bit is the smallish size of the camera. For 35mm slrs I like larger cameras although I don't have large hands. I love the feel of a Spotmatic, K1000, KX, etc. I ended up selling the LX last year but I'm glad I owned one. The one thing I do miss about it is the fantastic metering system, great for night shots.

I leave the digital work for the urologists and proctologists.
How about the widest single unassisted metering range of EV - 6.5 EV to to EV +20 that is unequalled by any camera past or present. Couple this with realtime monitoring of the scene - making adjustments accordingly, and aperture auto exposure for as long as it takes or battery dies and it is the right tool for night shots. I've tested both of my LX's and they meter nearly identical for exposures > 2 hours in a controlled setting.

I don't know of an external meter that can match the LX's single metering range.
The Pentax LX wasn't and isn't my camera of choice and thus I don't own one. But speaking of its shutter I do like the horizontal shutter better than the vertical one. I don't care for high shutter speed above 1/1000 nor high flash sync speed.
I don't think you are a heretic at all. No more than I believe that I am a heretic just because I haven't found a single Nikon that I have been able to bond with, though I have tried several over the years trying to decide what everyone else sees in them.
Besides, if everyone loved the LX, goodness only knows how high the prices on them could go on our favorite auction site.
I like mine a lot, but I do enjoy shooting with the MX maybe more. But for some things I do like AE, and the flash AE off the film plane is great. Metering accuracy is superb. The only thing it really needs is AE memory lock, but that's curiously lacking on all Pentax AE cameras.
I wish the MX had the (non trick) MLU and had the film speed range of the LX.
Complaints that it's too small are odd to me. The MX is smaller and that's one of the reasons I like the MX. But the LX feels fine. My K1000 (a gift - I'd never buy one considering I can get a chrome MX for the price of one) feels like a brick in comparison. (A less well built brick - it's a Chinese made one and frankly feels cheap, but works ok.)
