I’ve read a few of these alledged stories in diffrent forums about stuttering zooms. I don’t doubt that some are experiencing a problem when they attempt a zoom when using the rocker. However, just for the record, I have yet to encounter this problem with my EX3 and I’ve owned it and used for nearly a year.
One can’t help but wonder how many are actual physical problems with the lens and how many are user issues.
And if you want to get technical, it’s not Sony but Fujinon who built the lens. So any issues with the lens should be directed at them.
Just something to think about.
