This afternoon I had a wee wander round the National Musem of Scotland and got a few good photographs.  However I found quite a few of them had noticeable amounts of motion blur.

I think this is due to the not-enough light (or the often dark subjects) and my main lens not being able to go wider than f/4. Last time I was in there I was using my 50mm lens and shooting at f/1.8, which made a big difference.
