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.

Most Pentax lenses stemming from the manual focus interchangeable K mount lens era forward (not stemming from the screw on mount lens era) will contain an autodiaphragm mechanical linkage apparatus which stays wide open and then automatically closes to the selected lens aperture f stop diaphragm setting during shutter tripping, then reopens (after closing to an operator chosen aperture value f number from the respective lens control, as was TTL metered and selected for exposure during a K mount MF film camera SLR user picture taking protocol process); the lens also generally tells most MF SLR camera bodies what aperture value is selected on the lens f stop ring from a second mechanical link carried from the mounted lens to the in camera body meter. However, many such manual focus and mechanical linkage optics do not offer full AUTOFOCUS SLR camera metering interactive functioning--as many of these AF bodies are equipped by additional or exceptional electrical and electronics signaling contacts which are joined by mounting the lens between the lens aperture mechanism, the camera body, and the so supported lens. These intelligent design interconnection lens capabilities offer instant lens aperture to camera body meter interface, by use of TTL meter sensitive to such lens aperture interface connection contacts (which are established by a more evolved KAF lens mount with so manufactured newer aperture electronic signaling functions that the older lenses do not have). These lenses include the sharing of aperture information transfer through newer electrical contacts between a given mounted lens and the SLR body, and can convey too most recently: the lens maximum lens aperture; its automatic lens aperture selection range(s); the operator made aperture selection, or an aperture capacity being set to automatically function for in camera meter exposure selection; and telling the lens focal length. All the related connecting functions of the more advanced KAF mount lenses are signaled to or by these lens to body and body to lens KAF mount SLR camera metering and selected metering type interlinks for its expanded KAF lens mount camera system TTL multiple mode picture taking protocol processes. Such was not the case with non contact supporting K or M mount manual focus lenses.
I am sure this sounds complex, but it is the way that a greater variability for interactivity between interchangeable lenses, camera bodies, and camera users has evolved. Such information transfer is needed to establish the post modern camera system's expanded automatic focus, meter and focus program types, and lens to metering and metering to lens interactivity choices and capacities. With these capabilities for achieving greater variability, lens and/or camera selections and settings affecting exposure values for exposure component interrelationships happen through DSLR expanded control capacities offered on newer Pentaxes (offering more choices of metering interface, functions, and camera system capabilities). In order to achieve an automatic or preset in-camera meter selected lens opening--in addition to offering support for a user chosen meter aided manual exposure selection for imaging use--the post modern KAF and Kaf2 lens mounts grant their respective design evolutions for greater interconnectivity with the post modern DSLR AF camera (acting more as a lens control instrument than did the manual focus TTL camera and its K mount era lens with the lens controls in themselves being the source for lens control).
When mounted on Pentax Digital SLRS, only the A, F, FA, and DA Pentax made lens series can automatically interface their aperture information with on and by-camera made auto aperture selection(s). Over the years of lens development, starting with the A series, aperture information and feedback control capacity electrical contacts were added for the electronics transfer of aperture information between camera and lens. These connections established aperture setting indication, measurement, and feedback schemas for the metering processes of these cameras. For these, the A series lens will perform most, but not all, post modern DSLR lens metering cofunctions and cocapabilities. When Pentax created their first aperture information by contact information transfer lenses--with the A series, then next by autofocus lenses, with the F series--they designed new lens information transfer ability between camera bodies and these lenses (ability which the earlier A series does not completely emulate, and the K and M series fail to emulate). An A series lens does permit camera programming functions and automatic camera selection of its aperture value(s). The F series onward offer these features and further permit additional autofocus, follow focus, focus anticipation, and autoexposure on camera functions and capabilities. Some lenses have integrated chips to signal focal length as well.
F, FA, and DA lenses further evolved from having aperture control rings on the lens (F and FA), to not having these on the lens (with the later FAJ and current DA); in the later instances of creating lenses without the aperture ring, the interface and interconnectivity equipage became the norm for having lens aperture values totally selected for control by metering and override from the on camera meter operation interface(s). Call this evolution of the location of the lens aperture control from lens to body a marriage of a lens and DSLR camera body's increased capacity for intimacy. This is now the status of the Pentax DSLR. With a newer DSLR body one can take full advantage of this evolution for such an orchestrated intimacy by using the latest and lightest sensor-focused dedicated AF DSLR DA optics. This began to be made so with the optics that permit an A for automatic setting on the lens aperture ring, then, on up the lens roadmap to where the ring has disappeared altogether.
Where the on lens aperture ring has been eliminated (and some extra mechanical linkage to the diaphragm from the aperture ring on the lens stemming from the manual focus TTL K mount era lens thus disappeared) there is less encumbrance to aperture efficacy for full capacity autofocus and aperture control for a responsive use of the camera itself being the location for achieving greater pinpoint technical control accuracy. Less of the lens aperture apparatus to achieve the same exposure result equals simpler lens to camera functioning, less friction, greater interactivity and interconnectivity, and a more intimate body to lens functions mutual control interface.
This evolution of aperture interlinkage and resulting aperture information lens and body cotransfer ability means that a K or M mount Pentax lens lacks the capacity to signal and transfer lens aperture value information through electrical contacts to the post modern digital autofocus camera. When such a lens is used, imaging is still possible, but this considerably slows down DSLR photography processes. With the changes from AF TTL flash to AF Preflash TTL as another resource reality for achieving the exposure value mix, it becomes even more advantageous to have an AF era lens for its greater interactivity with the DSLR. For lens information transfer, where possible, an aperture ring with such a feature can be set to A for automatic camera body lens aperture control, or can be a nonuse feature if nonexisting. The A series lens still stems from a film age user manual focus & user manual exposure setting technology period, and carries only some of the interconnectivity and signaling interactivity potential of the manual focus film camera age into the autofocus and digital autofocus cameras interchangeable lens aperture and other lens information electronics transfer era. The A series, however, does not signal additional information about focal length, focussing, etc.--which other AF lenses may.
So, to respond to questions on the forum, yes, a Pentax digital SLR can be setup to receive a purely mechanically connected K or M lens, but not with all the aperture information transfer equipage of later lenses--especially KAF forward lenses. Even the early F series KAF lenses had tighter helicals than most of the later KAF FA, FAJ, or DA series lenses. This means that the earlier AF lenses focus or power zoom (an even more rare feature on certain of the F and FA series lenses)using more related motor battery power, and more slowly come to lock onto sharpness for the chosen subject than later FA or DA lenses with greater helical slop. The tradeoff is that the early mechanical and autofocus focus lenses are very well built, and still operate within tighter focus specification tolerances in most instances--even so some fifty years after being made. Some too have a bokeh which glows, and wonderful reputations for sharpness as well as fast aperture speed. The SMC, ghostless, and now chemically resistant Pentax lens glass coatings are applicable to the demands of the digital imaging sensorâ€™s on axis subject presenting lightwave receptivity needs, in most instances. See the Photozone site lens user surveys to determine which lenses from the A series forward will grant good digital sensor rendering results, as used with the smaller than 35mm film size sensor in these cameras.
The purely mechanical K mount lenses simply do not interface as well with the newer AF bodies because they do not offer the quick transfer of technical light values information, or available equipage to transfer useful information between the lens and the camera body. So, Pentax, in its corporate wisdom, offers, in some recent digital SLR bodies, an on camera user programming capacity to set up the camera to know which older K mount lens focal length is being mounted, and at what given aperture, in order to interface a mounted old K or M mount lens for its use. This slows down all metering and focussing protocol processes--for those older mounted lenses which only have the mechanical aperture interface to offer up to an electronic DSLR TTL meter.
Even so, there remain very coveted K and M series lenses which will require some extra programming and button pushing using features on most Pentax digital cameras for these to achieve through the lens exposure metering. Simply realize that their use will be even slower in application than with an earlier era film camera. Generally the pre-A series lenses will work, as then custom programmed for acceptance with the DSLR: as being manually set aperture priority optics, by user programmed and interactive digital camera lens exception criteria available on Pentax DSLRs.
Pentax has made most former lenses useable on the post modern DSLR. Even a K mount adaptor can be used on screw mount lenses. But, the losses will be the responsive possiblity of newer meter sensitivities, interconnectivity, and DSLR focal length sensing, aperture sensing, automatic priority, autofocus capacities, and follow focus. The gains of early K mount lens uses in some instances are found on the user surveys of lens use on the Photozone site, Pentax optics section. I still use my M series 20mm f4 (and A series 20mm f2.8) for many reasons, yet know it will slow down the photo shooting effort all the way around when using a DSLR. I still use too my F series zoom lenses, because they survived all these years for post modern DSLR use due to tighter manufacturing specifications and tolerances of yesteryear than generally exist for most AF lenses today. What would I like to now own, along with my K10D (and coming K20D) bodies, are a wide aperture very wide angle zoom that has no shadow or color fringing, no distortion, corner to corner snap and sharpness at all focal lengths, and can outmaneuver my worst photo strategies with smarter-than-the-photographer shots. For this outcome I would not care about the degree of interconnectivity, or the smaller than 35mm APS-C sized D sensor limitations on the use of and the related changing of the focal lengths of past optics . --Jay

I'm not a Pentax DSLR user, but my understanding is that all Pentax bayonet lenses can be used on a Pentax DSLR. I think that both the auto diaphragm system and the meter will work, at least in basic functions. There may be exceptions, though, or I might be slightly optimistic. The bayonet, in any case, is compatible.3. From : raymond kong (email@example.com)

Okay.. I am new to Pentax. I was offered a Pentax Digital SLR, Question, I notice there are plenty of pentax lenses at Ebay - can those manual focus Pentax lenses beused on a digital pentax ? i.e. is the mount same ? I do know it may lose autofocus but how about there functions ?4. From : Pierre (firstname.lastname@example.org)

On development of the MIR Pentax Professional Camera Digital website. Hi again, LX fans. Having written preliminary background material for a Pentax Professional Digital SLR website, while interfacing with the owner of our site here, Leo Foo, we are opening up opportunity for regular LX site advanced users-contributors to this LX site to write me at the above e-mail address regarding their vision for their own contributions to creating such a site (i.e., those who may be interested in helping develop such a site). Depending upon the response, it may prove necessary to limit the field of developer participants after your responses. Ideally having developers from an international base of advanced photographic users will also be considered as to forming the proposed site development team.
Not all who respond will become site developers, maintainers, or gatekeepers, but all will be considered for such site development who respond in October at the above address. Please, in so responding, consider your imaging strengths and weaknesses, and what you may offer a new dedicated Pentax Professional DSLR site messageboard as a committed regular contributor.
If you are primarily a Pentax K10D user of advanced or professional photography background, have a keen technical mind, and can offer and synthesize creative written answers to advanced user questions on the Pentax DSLR Professional system, please write a page of background information on yourself--forwarded as a mini resume--and send such to me, as listed above. Also, describe what you may offer as to the proposed new site development. A review of this information will determine our development team and its consultative approach to the aforementioned site.
A maintainer/developer will need a solid foundation in photographic and digital imaging theory and practice, and a wide aquaintance with the Pentax system--since the introduction of the A, F, FA, and DA series of lenses. You should have been or be a published or advanced user photographic resource person, who would qualify for a telephone listing as a commercial or portrait photographer in any city of consequence (whether actually so listed or not so). You should know how to plan and proceed to do a location and/or in studio photographic shoot in your area of imaging expertise. For example, as a natural resource photographer, an industrial photographer, a portrait and wedding photographer, a medical photographer, a scientific applications imager, a media communications applications based imager, etc. Advanced amateurs also will be considered.
The proposed site messageboard will be written in English, so you should be comfortable forming concepts and writing in that language. Knowing the ins and outs of on location and studio use of the Pentax Professional DSLR system would be a strength favorably viewed to become a site maintainer. A maintainer is a person who wants to give back to the imaging community, gratis, one's at-large wisdom discovered in regularly employing the Pentax system since its introduction of lenses which transfer their technical information to within Pentax SLR body metering components. Certainly the use of lighting equipment, related exposure decision making, photographic composition, camera support equipment, various lens applications, photographer personal gear for efficient area of expertise employment, after image software uses, etc. is important to our site validity for its maintainer interface. Having the camera alone does not qualify a person to be a maintainer or developer. Knowing and using the equipment for visual communication goal outcomes may.
Our thinking is to open inquiries on a future Pentax Professional DSLR messageboard and forum to all Pentax DSLR users, but, to profile the site as being the K10D, and soon coming <12+MP Pentax DSLR body site (along with its followers forward). In other words, discussion on the uses of any Pentax DSLR, and related system use, will be encouraged. However, the primary focus will be on the use of the system as developed for employment since the introduction of the K10D (the first really on-time Pentax DSLR for advanced users, all other Pentax DSLR entries lagging behind other DSLR manufacturers system introductions over time).
I look forward, this month, to receiving information from probable MIR Pentax Professional DSLR site developer/maintainers. Let me know your thoughts and considerations, in addition to what is requested in this posting. The LX maintainers are from three continents; we are hoping for an international face for the DSLR site developers and maintainers who are committed to giving to the imaging community that which they have received over their lifetimes.

I agreed. Problem is, everyone has flocked onto the digital bandwagon. I had been to this site since the late '90. Influenced and bought myself a bare basic LX too (My primary was Nikon F3). IN relation to Google search, try type in Nikon F, F2, F3, F4, F5, Nikkormat, FM2, FE, FA, EM Canon all the manual focus bodies such as EOS-1n, EOS1n RS, original F1, New F-1, T90, A1 AE-1, Minolta XK, XD-7, Olympus OM1, OM2, lenses of various makers etc. This site has become an important reference source for mid-MF oldies and hope it stays for those in need of info. I guess one day it will goes into digital but there are so many goo sites in the market today and probably it should use another channel. I don't know how many of you had visited this new section:
it includes all the info for the Kodak DCS digital still bodies but will leoo be making an attempt for the Pentax Digital ? I am not sure as he is kinda busy traveling between China. But I did received a forwarded mail that a Pentax enthusiastic user may preprare one such a site and forum here. Hope this materializes (along with a Pentax lenses section - even for the oldies) such as what he did for the new/old FD/EF Canon, MF/AF Nikkor and MF Zuiko:

Prices on used LX equipment are seemingly becoming more reasonable, at last. This past week I was able to pick up a couple of freshly-serviced mint bodies, and spotless FB-1/FC-1 finder set for surprisingly little, about half as much as I would have expected to see them go for within just the past year.
I've often wondered if the "tail wags the dog" concerning this forum; i.e. if a lack of posting activity here brings about a dip in the marketplace. (It's really not so far-fetched; the mir.com board and this forum have always fetched a very high page ranking from Google when searching on the term "Pentax LX").

Personally, I'm still partial to my K-1000. But, I've always loved the Pentax cameras ever since I got into photography. I still use all my Pentax cameras (K-1000, ZX-M, and the digital SLRs, Pentax of course) I get a kick out of the "Pentax Loyalists" ads I see in the magazines, that read "...You once carried a K-1000 around with you everywhere you went." And i think, "What do you mean once?"9. From : AB (firstname.lastname@example.org)

Yes Dan, Have them repaired a CLA might do it.
Being able to shoot 1000's for no cost is all well and good - and I'm sure you can learn things - but is your success rate any higher? I too find the cost of processing a limiting factor but this does make me try harder.
Beyond all this, the LX is a fine simple camera. It has just enough options - TTL flash is great. I recently bought a Super A because it was in superb condition and these cameras go for peanuts. It's well built, accurate and reliable and it has TTL flash but all those extra modes are a hindrance to me, I find myself longing for the straight forwardness of the LX. So keep the old girls going.

David - the prefix IL of the two letters L & X in Pentax ILX tag is just a bold outline the letter "L" and is the normal way of showing the PENTAX LX name.
There was only ever one Pentax LX (although there were later special issue models such as the Pentax LX Gold, Titanium, etc - see other LX section of this website).
The normal and original Pentax LX (black body) has the ILX engraved on the top plate of the body next to the shutter dial, so is not seen in photos showing the front face of the LX body; but the ILX name is shown on the special limited edition 2000 model shown here:
