Kyoei Kuribayashi (T-Mount Variant) 35mm F3.5 Lens & Filter Set UV Photography For Sale

KYOEI KURIBAYASHI (CLONE/VARIANT) 35mm F/3.5 UV-CAPABLE LENS & UV-PASS/IR-BLOCK FILTER SET!THE PERFECT UV-PHOTOGRAPHY KIT, FOR ANY CAMERA SYSTEM!This is a variant/clone (a T-mount version, unmarked and custom-labeled) of the Kyoei Kuribayashi lens of UV photography fame! It exhibits similar UV-transmission capabilities as the original fixed-mount design (e.i. M42, Exakta, Nikon-F mounts), but instead uses a more adaptable T-mount design.(NOTE: You can easily find a T-mount adapter to use this lens on your DSLR. They are very inexpensive, and quite common, usually costing well below $10 USD. However, I recommend that you also look into obtaining an \"M42 Helicoid adapter\", if you wish to gain variable close-focusing capability with this lens for dedicated macro work.)
HERE\'S THE SHORT STORY:Over the years, I have acquired a good number of these Kyoei Kuribayashi clones/variants. Being as such, I labeled them myself, as you can see in the ad. I also improved on their design by making a few key modifications. I added a water-tight gasket (use of a custom-fitting rubber seal ring) at the front of the lens, where the front-element module screws into the lens body (to enhance resistance to weather/moisture and mold-growth), and I also permanently modified the filter threading to accept standard 52mm filters. Furthermore, although all of these specimens among my stockpile are in used condition (these are vintage lenses, after all), I have taken it upon myself to disassemble and clean out as much internal dust as possible (as needed and when present), hence restoring them to full functionality.These lenses are certainly not perfect, keep that in mind (many will have scuffing, paint loss, small dents, minor grease on the aperture blades, etc.), but they still have a lot of life left in them and are even likely to outlive you and me, given their remarkably durable build. (All metal! They surely don\'t make them like THIS, any longer.)I am going to be selling these individually. Grab them at this deep discount, while you can! Especially since I am also including a UV-pass/IR-block optical filter stack, making this an economical UV starter kit! The pricing essentially breaks down to $49 per lens, and $25 per filter (Two filters = $50), for a total of $99! I believe that you will not find a better bargain anywhere on (or beyond), for this lens/filter combo.As for camera compatibility: Just like the original (fixed-mount) Kyoei Kuribayashi lens, this T-mount clone/variant is a full-frame lens! Thus, it can be adapted to virtually any DSLR camera from Full-Frame sensor format and smaller!BE AWARE:Once more, for emphasis, given that these lenses are of vintage design, there may be moderate imperfections attributed to such lenses, such as some lingering (but insignificant) tiny dust particles in between the glass elements or minor cosmetic blemishes and/or dings and dents, due to extensive prior use. However, I only sell FUNCTIONAL specimens (with no mechanical or optical impairment). Your satisfaction is 100% guaranteed, or you are welcome to ship these items back to me. No fuss, no drama. (I am all about reasoned, level-headed relationships.)ABOUT THE OPTICAL FILTER-STACKING SET, INCLUDED IN THIS PACKAGE1. UV-PASS FILTER: 2mm-thick ZWB1 optical glass, mounted in 52mm-threaded filter ring (to fit the 52mm threading that I modified for the Kyoei Kuribayashi lens):This is essentially a more cost-effective alternative to Schott UG-11 or Hoya U-340. While it is not exactly identical to the UV transmission of UG-11 or U-340 glass (which is far more expensive), it is a suitable substitute - albeit at somewhat longer exposure times (typically by a fraction of a second difference, in bright sunlight). So it is meant to be a more economical option, yet still quite capable (which reflects its more reasonable price). I have been using the ZWB1 UV-pass optical glass for several years, now, and it sufficiently meets my needs. (The images seen in this ad can be obtained using the same filters being sold.) What\'s more, unlike some of the more expensive UV-pass optical glass out there, ZWB1 UV-pass optical glass does not seem to rapidly oxidize over time. Whereas, there are some types of more expensive UV-pass optical glass (including some types of Schott glass) that will develop a corroded, clouded, and obstructive oxidative film layer on its surface, over time, requiring re-polishing and/or treatment of the glass surface. Thus, because ZWB1 UV-pass optical glass appears more RESISTANT to such oxidation, this is actually an ADVANTAGE, and it adds FURTHER long-term value to this already economical alternative to Schott glass!
2.IR-BLOCK FILTER:2.5mm-thick BG39 optical glass, mounted in 52mm-threaded filter ring (to fit the 52mm threading that I modified for the Kyoei Kuribayashi lens):Not quite as superior in transmission peaks to Schott S8612, but still much better than Schott BG38 and BG40. In fact, I am of the opinion that Schott BG39 is only SECOND in desirable transmission levels to Schott S8612. And similarly to Schott S8612, it is a very aggressive IR-blocking glass, virtually eliminating any risk of IR contamination in your UV-only photographs (when cut to sufficient thickness, which is the case in my sale). However, BG39 is more cost effective, compared to Schott S8612.COMBINE THESE TWO FILTERS (ZWB1 & BG39 filters stacked together) onto the Kyoei Kuribayashi lens, to obtain UV-only images. Or, use the BG39 filter by itself (sans the ZWB1 filter) to obtain \"normal\" (visible-wavelength) images.By including this optical filter set in this sale, you are effectively getting a very usable and competentUV STARTER KIT, thus gaining the ability to take UV-WAVELENGTH and VISIBLE-WAVELENGTH comparison images!MY PRICING IS REASONABLEFor $49, you are getting the PROVEN and TRUSTED specimenof a Kyoei Kuribayashi lens. One that iswell used, but functionally capable and also modified with some custom improvements. Albeit, it is a clone/variant in T-mount design, which makes it more versatile, compared to the first-generation fixed-mount version.
For just an extra $25 per filter (two filters = $50), you are getting an UNBEATABLE starter kit for UV photography work!That\'s $99 for the entire set!Finally, my reasonable shipping cost of $8, which includes FULL INSURANCE COVERAGE, and SHIPPING TO ANYWHERE IN THE UNITED STATES!
I TAKE MY SELLER-BUYER RELATIONSHIPS VERY SERIOUSLYYou will NEVER find any serious issues with the used lenses that I sell. (No fungus, internal haze, cracked glass, etc.) I would NEVER feel comfortable about selling any lens specimen that I wouldn\'t want to use for myself. THAT is the measure of my lens assessing. Certainly, while such lenses are \"oldies\" (but goodies), I take the time to individually disassemble any lens with fungus/mold/haze (when present), remove it using the proper cleaning techniques, thus restoring the lens to a functional caliber of use.Furthermore, I pack each lens and filter starter kit with the utmost care and protection in mind, not only padding the lens and filters to shield them from the bumps and bruises of long-distance travel, but also complete sealing from moisture/humidity, too! (I utilize air-tight packaging materials, and humidity-absorbing desiccant packets.) Thus, this is about as big of a bargain as you will get! You can therefore be certain that your investment is protected to the utmost level of care in mind. I don\'t mess around!To be clear:I want to be a fair and transparent individual in all of my dealings.I am a reasonable person and I seek to form level-headed and honest relationships with other members, in order to cultivate an atmosphere of mutual trust between buyer and seller. I feel that so long as both, the buyerandthe seller, conduct such relationships (through mutual understanding), then there is nothing that cannot be resolved.PLEASE REMEMBER .....You will need a \"full-spectrum-modified\" camera, and also the proper adapter (whether a fixed T-mount adapter or a variable-focusing helicoid adapter) in order to make proper use of this lens and filter set. Thus, it is implied that you are well-rounded and properly-trained in understanding how to obtain and implement such mandatory devices and accessories, in order to use this lens and filter set for their stated use.However, if you have additional questions or concerns, you are always welcome to contact me.
