Following the detection of GRB 050701 by Swift/BAT (Boyd et 
al, GCN 3356), we obtained R- & I-band images starting 5.0 
hours after the trigger, at the 0.6 m and 1.8 m telescopes at
Mt. John Astronomical Observatory.  No new source is detected
within the 6"  radius XRT error circle (Hurkett et al., GCN 3560)
down to the DSS-2 limiting magnitude. We also notice that there 
is considerable extinction towards this line of sight.
