This converter multiplies the focal length of the attached lens by 1.4 at the expense of one stop of light loss.
The T5-1.4x is only for use with the M* 800/6.7 ED IF lens. It was designed specifically for this lens and the two were sold together. Due to its unusual design it won't fit other lenses.
