Just got a new lens, Sigma 21-35mm f/3.5-4.2. On the cheap as well, $40. So far impressions mixed. It is wide and it is relatively small, though with a 77mm filter thread it isn’t that small (it is pretty short though). There is a tiny amount of barrel sloop side to side, but otherwise pretty solid feeling. I think I prefer 2 touch zooms, at least at the wider focal lengths, but the push pull design isn’t to bad. More impressions and pictures later.
