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.

William, I believe that you may have interpreted the Pentax USA web site incorrectly. It is my understanding that they will continue to repair the LX for the foreseeable future. I recently spoke directly with a member of their parts department and she told me that Pentax has made a committment to continue supplying parts (and I assume service) for the LX indefinitely. This is, according to her, because the LX is a professional level camera. My understanding is that what has changed over in Golden is the ability to bring your equipment to them in person. There is no more walk in drop-off for repairs. All you have to do is send your LX off to them via insured shipment and they will contact you with an estimated cost for the service of your LX. They did a fine job servicing my LX except for the scratch around the speed adjustment knob. But I am not absolutely positive that they did that as the initial Portland repair center instructed that I send the body back to them first insisting that it be they who would than forward it to Pentax USA. Perhaps they did it validating my complaint that the blue speed indicator was not lineing up correctly. All I know for sure is that it was not there when it left my home either the first time or the second. I would strongly recommend that you follow the advice of those of us who have experienced less than satisfactory LX CLA's. I'm not pointing an accusatory finger at those whose attempts were less than should be expected as I believe that it has more to do with the fact that too few technicians are trained in a manner that is required to properly attend to a highly complex vintage all mechanical machine that the LX is. The owner and employees of the Portland service center were all fine people to deal with and came through in the end by footing the bill to have it done right by Pentax USA. Contributor AB has repeatedly recommended a UK eBay member known as "poundapint". Poundapint is Robin Gower of Harrow Technical. You may consider doing a google search for Harrow Technical and write him an email concerning your situation. He at least inferred to me that he may entertain the opportunity to receive units from outside the US for repair. It is my understanding that Robin was a Pentax employed LX technician and that he has many years of experience in repairing Pentax cameras. But I believe that at this time, Pentax USA is performing top level repair work on the LX as well. My understanding from the postings on this site is that Pentax USA still has within its employ an experienced LX technician. AB made the best point when he explained the importance of repetition and experience when considering the best choice for who services our LX's. This would pretty much narrow it down to those who work on LX's every day 5 days a week. Best of luck and please feel free to email me directly should you feel the need.

Re scanners: I've a Minolta DSE5400, run through VueScan, then Cinepaint, and print on an Epson 2200. It's all 16bit (48bit color) and it does make a difference, despite what others say. I understand that the new 8mp digital SLRs, especially the Canon 20D, can match this quality, don't have one so can't say. And it all starts with an LX and a SMC Pentax-M 50mm f/1:1.4. Print up to 12x18 and like the detail I see through a glass on the print. Pixels are visible at that magnification, of course, but the camera and lens provides image detail to the extent that when the clumping that occurs with the 8bit limitation is smoothed out by use of 16bit channels, even more detail is revealed. Gotta love Pentax glass, even the poorly regarded M versions. Also great bokah!

RE: LX repair/service: What I get is that there really are no dependable service facilities out there. PentaxUSA at Golden Co no longer takes customer service requests directly, if I interpret their web site correctly, and the horror story related by Michael about Advance Camera in Oregon would seem possible from any of the regional centers. The issue, it seems, is exactly who it is that will do the work. Even if a center has capable technicians, whose to say that the camera will be routed to them. It seems inconceivable that a factory trained technician would produce the work Michael reported, although it would seem inevitable to get that kind of work from some ham-handed kid. So the name of the issue is Trust. Who can you trust? I would think that anyone who is known by name would be more trustworthy, his/her having a reputation to protect, so that means private (not Pentax accredited) outfits. Question is: Who? I recall someone having mentioned someone who is very good because they love LXs (presumably fine mechanical cameras in general as well). Who would that be? Is there, in fact, a dearth of dependable LX technicians now available? Would it make sense for a retired fellow to take up fine camera repair just to fill a need? On that note, I see that "nikondave" on EBay has the LX repair/service documents available on CD. Has anyone gotten one of these? Opinions? Bill Tallman

Dan, Although I appreciate your drift, film scanners scan grain, and use pixel technology. In many instances the transfer confuses the formula you have advanced. I suggest you read the two test comparisons I already mentioned to be on the same page. --Jay

Okay, just one more variable and then I will stop.

Film resolution: (See: http://creekin.net/films.htm)

Slow speed Kodak and Fuji films look like they have a nomimal resolution of 60 to 80 LP/mm at 1.6:1 contrast and as high as 160 LP/mm at 1000:1 contrast. It is hard to determine the grain density. According to Kodak, a lens needs to be 3 times sharper than the film to maximize the grain (source: http://www.imx.nl/photosite/technical/highres.html). But clearly they are closer to 1:1. Using the equation sited:

1/R)2=(1/R)2+(1/R)2 (those are squares, not 2x)

the max system resolution of an LX using quality low speed film and a great Pentax lens is around 64 line pairs per mm:

(1/r)2=(1/160LP/mm of film)2+(1/70LP/mm of lens)2 And this is lower if you consider a lower contrast: about 46 LP.mm! So 160 pixels/mm should come resolve the maximum resolution of the Pentax image on slow speed films. Does this sound resonable?

So working on some math: 4000 dpi (of the Nikon) equates to close to 160 pixels per millimeter (4000 dpi/25.4 mm/in.) and 5300 dpi is over 210 pixels/mm. Since the best Pentax lenses resolve to 70 line pairs/mm, do you think 160 pixels will resolve 70 line pairs properly? Theoretically, 140 pixels will image 70 line pairs, if lined up perfectly. But we aren't talking about perfectly lined up lines but rather real world gradiations. Anyone had good results at this resolution?

I've read and kept up with the discussion of scanners on this LX message board and have researched other websites as well. With technology, one must try to hit a moving target at the right time. If newer scanners are coming in the spring, I might wait. While the cheap scanners are aluring, the more expensive ones are faster and can do large formats. But the expense makes it hard to get your return in a reasonable amount of time. Thus my pondering. But we all know this. Let me get back to the LX. I have never scanned one of my LX negatives. What kind of target resolution (in MP) will capture the capabilities of 35mm media (negative and positive) from my LX, assuming optimal lenses and small grained films? At what point am I getting diminishing returns?

Choen, According to the bar coding source web address your reference is a spoof, non-existant. But this raises the spectre. This year we should see the professional digital SLR Pentax release. Soon time to enter the big waters and sink or swim will come the Pentax way. --Jay
