I hope it's ok if I insert one which relates more to the handheld mentions above, although it was med ISO - 200. Before I explain why I have posted, I absolutely know it's not great art, it's simply a bit of a building I had to get and had seconds, literally, to get it as the rain was starting.
I pointed the thing in more or less the right direction and fired off at a few different angles. I was truly shocked to see reasonable results at 1/20th! Normally I would steady my breathing, try to control the shaking (must try stopping my heart) rest against anything more solid than me and ever-so-gently squeeze the trigger. And still usually end up with a blur. Funny old world.
