Modern Classic SLRs Series :
Pentax LX - Message Board/Guestbook

Industry wide indications and ceasing film body development by Pentax altogether in early 2003 more than suggest the manual focus Pentax LX will not be having an upgrade (except, perhaps for very rare Limited Edition Models hand assembled by special commission by the new HoyaPentax Corporation). In 2008 Pentax became a division of Hoya Corporation, which had together with Pentax released jointly developed professional grade optics (since 2005); Pentax has shifted its attention to development of auto focus Digital SLRs having build qualities constructed for the long run--now with weather seals--like the LX. You may use this site for common support and sharing of mutual users knowledge or experiences among yourselves. You may also use this message board as a guestbook for the advanced users Pentax SLR cameras from the LX forward, including many such auto focus film cameras, and Pentax digital SLR cameras. We keep the site going too for the WORD SEARCH FEATURE found here as to its magnificent K mount system user archives: as have been shared here for many years. Have an inquiry related to Pentax gear? First try KEYING IN YOUR KEY WORD(S) for a preexisting archived response on your subject of inquiry from this LX site. If your inquiry or sharing is from advanced users K10D, K20D, or K200D SLR needs, proceed on to t NEW PENTAX ADVANCED USERS K10D, K20D SLR site.

This LX site was specifically created for the great Pentax LX SLR camera model(s), and now has incorporated increased opportunity for an expanded interchange with the introductions of the Pentax K10D, K20D, and K200D SLRs to include advanced and professional digital user models. Interchange is encouraged with the intention to continue as a forum for advanced system users of past K-mount film based SLR systems and the mentioned Pentax DSLRs. With decreasing forum traffic here, and enthusiasts moving on with SLR digital imaging products futures, we hope the continued convenience of this site and its past Pentax advanced LX users data archives--provided by the database KEY WORD SEARCH FEATURE found here--can be very useful to you. Most past site user techniques, systems components, and lenses of Pentax advanced applications--as have been past examined by users on this site--are still of use regarding the newest Pentax SLRs.

Please note that all messages are being checked for content, prior to being posted on this message board. This is in an effort to curb recent spam massages clogging up the flow of mir.com forum pages.

I've just got back from the big 3-day NEC show in Birmingham, and will also be getting ready for the London Wembley show next month, plus hundreds of new images to edit, plus final editing stages of my video...so sorry for not checking all recent posts until today.

The Pentax LX 2000 model tends to be a very sought after item, so when one does become available, it is quickly snapped up by collectors. The most recent LX-2000 kit sold for a very high price on Ebay.

Regarding the big MF Pentax SM 135-600mm F6.7 zoom lens(4070 gms weight, filter size 52mm, length 582mm). This is quite a rare item, although a few have sold on Ebay during the past month, so keep an eye out for more. It is a solidly built lens, but is quite slow to handle and needs a sturdy tripod for best results.

Mercer, I had 135-600 once, and I do not know if you are aware how big it is (4kg!). Lens has manual(preset)aperture only and is designed for use with tripod, so do not take one if the tripod collar is missing. Also,one touch zoom/focus on such a monster lens does not help ease of use. Lens also extends when focused. If you find one , look if it has a special close-up attachment suplied with the lens. Without it, it can not focus closer than 6m, with the close-up lens it goes down to 3m. Optical quality is very good for the range and the time when it was designed (1972). But, there is no ED,AL,IF and other goodies of the modern lens design. M.

I'm looking for a Pentax 135-600 zoom. Is there a seller out there? How does it optically compare with modern lenses?

Philip, I have forwarded the email to your address that appears on the list. It's to do with helping to maintain the site.

Because of the compound, dynamic and interconnected nature (hey, I'm starting to sound like Jay!) of the LX metering/shutter control I have found testing in a shop etc. quite deceptive. I think you're right, Robin and the test bench is the answer.

Thanks for the advice/info AB. I did the usual on site testing, just simpy running through the shutter speeds on auto/manual in-store and it seemed OK.
Although I have the warranty from Jessops (should it be unreapairable etc..) I, for myself, do not feel confident for whomever Jessops would send it to for a proper job as we all know it takes a properly trained person to mess with an LX and I have heard of general camera repairers making matters worse!
Therefore I have decided it would be money well spent for Robin at Harrow Technical to look at it/service it and advise on any problems. Naturally I cannot claim a service from Jessops, but if he indicates any major prolems I can then go back to them with the details.

Finally, would Mico or Globetrotter care to help wih regards to the previous posting concerning password? changes etc... as I'm a little unsure of what is indicated may be necessary for me to do?

Thanks

Philip

Hi Philip

1. As I understand it, it affects the shutter in that the shutter cannot fire until the mirror is up. I don't think it affects the shutter speed/timing once it is able to fire so exposures should be correct but there is a delay before this happens meaning you may well miss your subject.

2. The LX system is quite complex and has a few modes of operation. Firstly manual speeds 'X' and above are actually mechanically controlled in the good old-fashioned way, manual speeds below 'X' are electronically controlled (so run some tests with these slow speeds). On Auto all speeds are electronically controlled and are step-less, controlled by the light meter at the moment (or very close to) of exposure. At faster speeds (high illumination) a reading is taken from the surface of the shutter curtain after the mirror has risen and before the shutter fires (this is pretty impressive stuff) at slower speeds (low illumination) a reading is taken from the actual film surface and the shutter controlled by this reading. Quite how it figures all this out and which it is going to do, I know not.

Quite a complex system then and it needs an experienced troubleshooter who knows his onions. Despite this, my experienced troubleshooter has been floored by more that one LX. Your problem may be as simple as the shutter magnets; the switches, the ISO dial or it might head off into the gloom and frustration of the un-fixable LX... I hope not. Still you are in a good position, if it can't be fixed you can get your money back or get Jessops to send you another example from one of their shops nationwide.

One question. Are you absolutely certain the camera wasn't behaving this way when you bought it? Maybe you just didn't notice; maybe you didn't use it enough. I find any 'new' LX needs thorough and repeated testing in all modes of operation until you can be reasonably confident that you have a good-un.

Good luck
AB

Pentax LX is a lovely SLR to own and use. The only thing I didn't like is the lack of a proper hand grip when used with the MOtor. Could have designed it better but performance-wise, it is excellent. For a long time Pentax has never come out with another classic in the class of the comparing LX. I got a used unit again for collection (LX 2000 and LX Ti is too expensive !).

On the subject of LX bodies,the one I picked up recently (serial no. 5263xxx) has now begun playing up. It seems similar to the problem I had a while back with my other older one, whereas when set on auto the shutter/mirror became erratic, appearing to expose for much longer than the indicated meter reading, or sometimes even shorter!. As it is still under warranty (Jessops) I intend to take it back when this film finished. Not sure though who they use as repairers?

The shutter etc.. seems to be perfectly OK when I set it to manual speeds, just plays up on auto and unlike the older one (now fixed) this newer one appears only to stick open longer and not shorter..

I therefore (in my little knowledge of known faults) have a couple of questions:

1) If the camera develops sticky mirror syndrome, does this effect only the mirror itself and not the actual shutter operation? Not had a film back yet since it started to see how the exposures have come out.

2) Why would this happen only when set on auto and not when using manual shutter speeds?
