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.

I've not located a A35-105 f3.5 as of yet (early days). Could you guys recommend an alternative? Maybe the A28-135 f4 ? The range is a little broad for my needs but it looks like it might be the next best thing? I might pickup an A50mm f1.7 anyway, just to keep me going as they seem to be available and cheap (circa £35) until I find a 35-105 etc. Many thanks. - Ian.2.

Hi Jay, In fact that was a SMC-F 28-80 that I purchased for US 80 , not "Takumar" or "Pentax-F" as it was named in Europe. I had a chance to try non-SMC versions and was not excited, with mechanics in particular. "Thank you NON-SMC versions" means that people often confuse SMC and non-SMC versions of the lens and underprice the SMC ones. 28-105 AL IF is in fact SMC with addition of Ghostless coating technology. Pentax still does not have separate designation for the later one. BTW, I am working on making a 1/2 half stop click betwen F4.0 and F5.6 on my SMC-A 70-210/4.0. That will be my new MAX. working aperture with that lens. Improvement in image quality is significant. Still, I will benefit from F4.0 while focusing. M.3. From : Anton (email@example.com)

There's a to-do on the PDML, someone spotted a release stating that Nikon are to abandon further development of film cameras and indeed will actually stop selling them in Japan as early as April... the digital revolution gathers pace. I just hope film doesn't disappear or become overly expensive, I'm prepared for a price increase and a reduction in variety. Time will tell. p.s. err Lisa-Marie, do you model?4.

Mico, I found your last line on your last e-mail a bit cryptic. DId you mean your purchased another 28-85, and that proved to be a non-SMC Pentax-F lens (sold in the USA as the Takumar-F 28-85)? This is still a very very good optic, even is so. On the 28-105 f 3.2, yes it is a non-SMC (though I mistakenly listed it below as an SMC). In fact, it has the newer Pentax "ghostless" coating, which exceeds the SMC coating process and result. Let me know what you meant by your e-mail. --Jay5. From : Jay Hart (email@example.com)

Teleconverters for professional use, and AF. "Abe's Camera of Maine" (as listed on the internet, however, it started there but is in NY now) has the Sigma AF 1.4X APO Pentax mount converter in clearance for $29.00 (list is $159.00), plus shipping. It has been ordered; I'll let you know its total manner as soon as I test it. It is as good or better than the Kenko Pro 300 series 1.4X AF converter, especially when used with the Sigma 70-200 f2.8 ex AF and their 300 f2.8 ex AF.
Will it work with the Tokina 300 f2.8, or like fast Pentax AF optics? This depends on the compatible marrying of their respective in-mounts rear & front optics, and electrical contact compatiblity. On the Sigma lens website the converter unit is not recommended for AF with any but a few f4 lenses and faster, whose rear groups do not interfere with its own optical system as fixed within its mounted shell (none slower work with its AF, a few others are listed as OK for MF. This includes the 400 5.6 APO macro of earlier communication exchange on this site). This confirms that, in order for most converters which carry through AF electrical and mechanical linkages to work with lenses attached to this type of converter, f 4 and upwards is a magic number for AF function with a lens which does not crash into the optical system of the 1.4 x (as mentioned, as fixed within its mounted shell). As to Pentax camera's electrical contacts the professional converter made by Sigma may carry only its own contacts alone for its own lenses alone as may be found inside of the converter shell contacts on the receiving side for a lens (these then would differ from such contacts carried through to its own KAf mount. The mount for its receipt of other brand lenses may just be a K or KA mount according to an esoteric design.). It will soon be clear if it has maintained the Pentax A, F, or FA type contacts on its lens receiving end.
In optical design it is somewhere between the Pentax 1.4Xs and 1.4XL as to its resulting optical/mechanical construction. Unlike the Pentax 1.4Xs, it will interfere with Pentax FREE rear element group lenses in attempted marrying (for example, interfere with the likes of the A 70-210mm, or A 100mm Macro, or A* 300mm f 4 handholdable). Its front optical element, in its shell's casing, sticks forward, but not beyond the K-mount on its receiving end, unlike the Pentax 1.4X L. Since it is designed only for long telephotos, of Sigma manufacture, only the price, with knowledge of its rare earth element quality, was the draw for me. And I have been looking for such an AF converter, if it proves to indeed be one beyond its own manufactured product line.
I am hoping it will AF with other brand lenses, but, as I am hopeful for a non-HSM 120-300 f2.8 ex Sigma to be released next year in a Pentax AF mount, I will probably have to wait for it to remove the veil here to see if it is a candidate for a good marriage. --Jay6.

Wow, expensive, Anton. Although, they are probably punishing you a bit for sending them a lens with a few "extra" parts. M.7. From : Anton (email@example.com)

Jay, it is nice that you had a chance to test all those lenses. As with all other lenses, maybe I have just had an exceptionaly good sample of 28-105 AL IF for my test. I was not 100% sure if it was sharper than my SMC-F 28-80/3.5-4.5 but after your experience, I think that I will stick with my old "F" lens for now. BTW, I have just bought another, mint "F" lens for aprox. 80US! It is so under- estimated, and I do not complain about that, not at all! Non-SMC versions of the same lens, THANK YOU...9.

Mico, After doing detailed tests of the SMC 28-105 f 3.2, and the SMC 24-90 f 3.5, I have ruled out the former for the latter. There is really no comparison. For example, in the 85mm portrait range as to facial detail, the latter lens is 1/3 to 2/3rds better, and shows little distortion in the wa range, compared to very obvious distortion with the former. The 85 f 2 M also excells over the former cited optic from f 2.8 downwards. And it is known to be a bit soft on edges (not bad on detail, and is an excellent choice for portraiture for many reasons). Even my SMC 28-85 F series f 3.5 is better in test slides shot, scanned at max resolution on the Minolta slide scanner 5400, as to detail at all focal lengths over the former mentioned zoom. It just is not sharp enough for my professional use (FYI). Though the 28-105 is a bargain lens in a sense,and offers a hybred rear element, and is SMC, I can only recommend it over similar 3rd party consumer optics. --Jay

Ian, I use the A 35-105 often; it is very well made. For a zoom it is excellent in all respects. It is hard to find used at a good price, for it retains a good reseller value. --Jay
