  Two-dimensional (2,2) supersymmetric nonlinear sigma models can be described
in (2,2), (2,1) or (1,1) superspaces. Each description emphasizes different
aspects of generalized K\"ahler geometry. We investigate the reduction from
(2,2) to (2,1) superspace. This has some interesting nontrivial features
arising from the elimination of nondynamical fields. We compare quantization in
the different superspace formulations.
