I'm offering here before I put it on eBay a classic 1:2 Asahi Optical Company Super-Macro-Takumar Lens, that is in truly beautiful condition in every way. Since this lens is 50mm the distance from the focal plane to subject gets short at 1:2. The lens comes with both front and rear original lens caps and a beautiful condition leather lens case.
This lens is a 1:2 capable lens. There is another lens by Asahi also called a 50mm Macor-Takumar that has identical optics, but is capable of true 1:1. To achieve 1:1 this version of the lens has to be used with an extension tube while the 1:1 version has effectively got a built in extension tube.
This lens is an M42 Screw Mount, and like all the M42 Pentax lenses will adapt to Canon DSLR's using an inexpensive and readily available M42 to EOS Mount Adapter and with that will focus all the way to infinity. It may also work with other camera's, but I do not have personal knowledge beyond Canon, and therefore leave it to interested people to research and determine compatibility issues for themselves.
I have included some images I took with this lens mounted on my 18Mp Canon DSLR using an M42 to EOS Mount Adapter. The image of the US Dime shows the 1:2 Macro capability, since the dimensions of both a Dime and the Canon Crop Sensor are easily determined. I also took a picture of a house across the street from my residence to demonstrate this lenses infinity capability with a Canon DSLR.
Price is $140.00 with insured USPS Priority Mail shipment anywhere in the CONUS. If outside that area, PM me for shipment costs. I prefers PayPal but other payment arrangements are possible.
