EBC Fujinon-T 100mm f/2.8 lens - $109Sold via eBay plus shipping
Sears/Sekor SX 55mm f/1.4 - $15 plus shipping, but read below
Here are two less common and well thought of M42 lenses with some minor issues. The Fujinon-T 100mm f/2.8 lens is externally pretty beat up, but functions normally. I have adapted it to close down manually, for use on a DSLR; this was not a destructive process and could be reversed. Also I repaired a major dent in the filer ring such that is now does accept filters and lens caps. It has seen plenty of use and has external blemishes and internal dust, including one very large speck right in the center - no effect on images that I can see, but it is there. The lens is incredibly compact for a 100mm, and takes great people pictures. Generic front cap is included, and "Konica 100" case. I don't have a rear cap but will throw a 2X TC on the back to protect the rear element, no extra charge. There is a lot of love for this lens out there on the internet, maybe you will love it too!
There's a lot of love for the Sears (Mamiya)/Sekor as well, but this one has more issues. Mainly, I did something wrong converting it to manual aperture, and now it will not stop down at infinity. It will stop down at any other focal length, and you can turn it too infinity after stopping down, but at infinity it freezes up. I tried a few things to fix this without success, and I would judge it probably not repairable to original condition at this point, although quite usable as it is. But not on a Pentax DSLR! The rear of the aperture ring sticks out, preventing it from being able to use a standard M42 to K adapter. One could probably sand that down, but I do not want to try. I did use it on my Q with good success. It would work on a bellows or on extension. And probably on other types of cameras as well. The rubber ring for focusing fell off, and it also has a big speck internally, to go with a tiny scratch on the front element. Anyway, you can see why it is bargain priced. :-)
Shipping $8 per lens, $10 for both in the US. International shipping available, please ask about rates to your country. Lower offers will be considered, but a full price offer will take 'em. I won't mark as a "gift" for customs purposes, sorry. PayPal is the preferred payment method although I will consider other methods if you strongly prefer. All items can be returned if not as described for a full refund, but please read descriptions carefully and if you have specific concerns please ask questions first. Thanks for looking, and happy shopping! Nick
