I realise that this site has already descended into being a camera tech blog; and this is not going to help, but….
I seem to have been indirectly responsible for a few of my gentle readers investing in the very fine Panasonic GX1. Those readers may like to know that Panasonic have released a firmware (or as we call it in this home, spermware) update for the GX1. You can, and probably should, get it here.
You will also notice that you can also update the spermware of your lenses; and the rather excellent 100-300mm has an update too if you happen to own the lens.
