One of my favourite lenses is the Sigma 30mm that I have had for years and years and some more. It is starting to look a bit weathered but it can be stopped down to an aperture of f1.2, that I can swear it is capable of seeing in the dark. Naturally when compared with an ISO of 800 or a little bit higher.
We visited Valletta over the Christmas period of 2016. Not all that long ago but having just endured January, it feels like a very long time ago!
