A remarkable lens from Japan, very sharp wide open, of the famous zeiss inspired design with preset aperture. It's well made, all glass and steel, with excellent color and contrast. The optics in this lens are amazing, it is simple and it works. It's bokeh and colour rendering are brilliant and it's as sharp as a razor. This is one of the mythical lenses of the days of lore, and hard to find even on ebay. There is about 340 degrees of rotation on the focus ring. The lens came with a 2X adapter as well. This series of lenses (model 680) were made between 1962 & 1969. The included tele converter is shown in the picture. This gave the kit the twin tele name.
Also known as the Taisei Kogaku [Tamron] Tamron 680 Twin-Tele 135mm f/2.8. A rare lens with the hard to adapt praktina mount. Mounting this lens onto to a EOS Rebel won't be easy. I have been trying to source an adapter for my Canon 600D Rebel but so far all information has pointed me to praticka B mount adapters…
One thing to be aware of when purchasing from flea bay (eBay) and other places is look for any instances of fungus matter inside the lens elements. It can be either in the front or the back. You can't clean fungus easily with these lens since the cost to have them cleaned is not proportionate to how much they cost. The expense is more than the purchase price. Nothing makes you feel worse than a huge spot of fungus or the beginning of fungus growth. So make sure you double check and look over more than twice over pictures by sellers online and in person.
There are remedies out there that say you can destroy it by placing the lens on a windowsill and let the sun take care of it. This can be met with some success but in actuality may cause the lubrication on the aperture blades to run or even leak causing the aperture mechanism to stick and lock up rendering it useless.
So take these words of wisdom and inspect lens merch with care.
For a long time, this venerable and formidable pump house has withstood the treachery and explorations of many urban explorers. Only a few have ever found its true location within the state lines of New York. Before, only well researched urban explorers found this pump house long before it graced the pages of Will Ellis' Abandoned NYC's long heralded and well-published website. It has stood for many years from the gaze of any unsuspecting explorer travelling within the state who may by happenstance found it just by driving. Unfortunately, you cannot "drive" and see this pump house. This place is located deep in a mixed-use neighborhood encased in businesses no one unsuspecting would find for it to be located there at the end of the adjoining driveway.
Once inside, the treasures to behold can be found. Inside you will find old boilers, coal dust, century-old coal, a flooded basement, three entombed car frames and an infinite supply of remarkable graffiti artwork. Thi…
