I am hardly a pro. I am touring Holland now. I use my iPhone primarily. Take out the Sony Nex7 for low light and shallow depth of field shots, relatively rarely.
I shake too much for the lightweight smart phone camera. The galaxy does well for what it is when I’m steady enough.
I’m used to a 35 SLR body and I guess I will until they go away.
Early this year I switched from Canon to Panasonic and love the Lumix. I still haven’t touched on all the features.
A weekend back there was one of those charity run/walks (I walk) in a rock quarry. The sky was so questionable so I left the lumix at home and took the galaxy. It did OK.
