F stop is 2.5 but the macro focus is terrible at the moment. The software update requires me to copy it onto an SD card to the root file 🙁 This is the bit I can't do and even though a few people have tried to explain, it's beyond me. I'll just have to wait for my daughter's boyfriend to do it for me I think. Anyway, in good light the focus speeds up considerably so it's just a bit hit and miss for now. That aside, I really like this camera. It feels very solid, the lens is small and dainty and there are lots of access buttons seemingly in all the right places. It feels good in my hand. In comparison, the X1 feels like a piece of soap, just waiting for me to drop it!!! I like the colours too, my daughter's very fair (redhead) skin comes out right and not pink and ruddy, even her hair colour is coming out true so not a lot to complain about so far 🙂
