摘要：

A new K-band (2.0-2.4 mum) image of the gravitational lens system 2016 + 112 gives the clearest view yet obtained of the two lensing galaxies, which have K magnitudes of 17.2 and approximately 18. The fainter galaxy is extremely red, with r-K almost-equal-to 7.7 mag, and while no spectroscopic redshift is available for it, estimates based on colors suggest a redshift significantly greater than that of the brighter galaxy. This has important consequences for models of this system.
