What reviewers say

History

The portrait lens of the launch trio: five elements in four groups, 240 grams, 46 mm filter, one-metre close focus, $660 in 1995. On film it draws the way a Sonnar should — Emulsive’s Matthew Thompson would pair one G2 with the 28 and another with the 90 for weddings — and it is the lens the autofocus handles worst. Drew Chambers found the G1 struggled to focus it for portraits; Ibraar Hussain put the G2’s hit rate with it near half. The trouble is the body’s phase-detection at long focal lengths and close distances, not the glass.

Bought cheaply for that reason, and worth it with the discipline the manual describes: centre, lock, recompose.
