We present UBVRIz' photometry of the gravitational lens candidate CLASS
B1152+119 obtained with the Nordic Optical Telescope. The two QSO components
are resolved in the B, V, R, I and z' bands confirming the lensing nature of
the system. The z=0.44 lens galaxy is clearly detected in B, R, I and z' and
its position is found to be almost coincident with the faint QSO image which is
heavily extincted (relative to the brighter QSO image) by dust in the lens
galaxy. The extinction curve of the lens galaxy derived from the relative
photometry is well fitted by a Galactic extinction law with 1.3 < R_V < 2.0 and
E(B-V) ~ 1. From a simple model of the system we predict a time delay of ~ 60
days.Comment: 6 pages, 7 figures, accepted for publication in Astronomy and
