Originally posted by lotech Thank for the reply guys, I finally 'fixed' the stiff mode dial with some lub, and I got the KX as well for backup. It was a disappointment being a high end model the Super A missed the mechanical backup, like the Minolta X700 I owned before I switched to Pentax. I may pick up a used LX again later on, I got one before but did not like it too much due to heavy shutter shock and noise, I got the Minotla XM which has interchangeable prism too and very heavy but softer at the shutter.
The SuperA/ Super Program wasn't exactly a high end model. It was at the top of the amateur end for Pentax and was similarly featured to cameras from other makers at the time.
There were very few electronically controlled cameras in the mid to late 1980s that had any mechanical shutter speeds, and those that did were generally just using the flash sync speed.
The LX was a notable exception, but it was a big price jump from the Super Program to the LX.
The Nikon F3 would shoot at it's sync speed with no battery, as would the Nikon FE series Both synced a half stop faster than the X-700 at 1/90 sec.
The LX will shoot mechanically from it's sync speed of 1/75 second to 1/2000 second. No batteries are required for these speeds, though obviously no metering will happen either.
The LX does not have especially heavy shutter shock. It was one of the smoothest film cameras of the era, and wasn't especially noisier that other cameras of the day.
The X-700 did not, to the best of my knowledge have any mechanical shutter speeds, it was 100% battery dependant. I just checked the owners manual and no mention is made of any mechanical shutter operation.
Also, the X-700 had a very poor information readout when shooting in manual mode and a relatively mundane sync speed of 1/60 sec, which was typical of cameras from the 1960s onwards.
When many cameras had gone to vertical shutters and a 1/125 sync, and other higher end cameras that were still using a horizontal shutter were giving flash sync speeds in the 1/75 to 1/90th second range, the X-700 was still 1/60th second.

Originally posted by Lord Lucan Mechanical shutters at least for back-up were something that professionals, the most conservative of shooters, demanded long after electronic shutters were taking over the lower end of the camera market. Horizontal shutter curtains and FP flash sync sockets were other examples. Nikonians howled when the all-mechanical pro-grade F2 was replaced by the F3, which was similar to the LX in having basically an electronic shutter but with some mechanical back-up. The F3 only had back up at sync speed, and used a separate button for it - not as good as the LX.
It was understandable especially for pros - you did not want to have to change an SR44 button battery in the middle of a wedding shoot, even if you had thought to bring one. But with a new generation of photogs, mechanical back-up died out even at the top end, and the Pentax A series were during that time, and were not aimed at pros anyway (the LX was still in production). People came to accept the possible need to change batteries during a shoot, especially as batteries became bigger (less fiddly to change), and today grips contain what are in effect your back-up batteries anyway.
As a wedding shooter during that era, it was just part of the prep to pop fresh batteries into the camera as part of the equipment prep for the job. One of the weaknesses of the LX was it's refusal to use flash if the subject was backlit by more than 1/2 stop. I got caught out on that once, and learned after that to pull the batteries out of the camera and let it run on mechanical when I wanted reliable flash operation. I wasn't using a TTL flash at the time, my Metz 60 CT-2 was capable of TTL, but it was so accurate on it's own that it wasn't necessary.
Fill flash was not the LX'x strongest suit.
