AF- Apogon (Longar) 1.4x Tele-Converter with HFT coating
This very high quality tele-converter was designed to be used with the 80mm f/2 Xenotar, 180 f/2.8, and 300mm APO lenses with minimal loss of image quality and only 1 stop loss of light. The 1.4x also can be used with many of the other lenses in the 6000 series and also the AFD lens line up.
Note this lens will not work with the 80mm f/2.8 planar since the rear of that lens will hit the glass optics of the extender. Also this will not work directly mounted to the 150mm APO-Symmar for obvious reasons, however it will work with extension tubes in between.
The AF-Longar supersedes the previous 1.4 tele-extenders and is designed to work with AF lenses. It's possible to stack two of these together to get a 2x Extension.
The minimum focusing distance of the lens with the 1.4x added will not change, so the teleconverter is also suited for close-ups and macro work.
