Seeking advice about X-100
The quality is excellent up to 18x12. I've not printed larger than that, but it certainly looks like it will go larger with no problems.
The lens is excellent.
RAW is fine with the X100, it has a standard Bayer sensor. LR processes them very nicely.
I imagine once you start using the X100 you'll find the Sony gets very little use. Don't get me wrong, the NEX7 is a spectacular technological achievement, but it just doesn't do it for me.
From your post I suspect you will fall in love with the X100.
If you have some galleries you can link to I think I could probably say for sure. It's pretty easy to tell from the kind of pictures you take.
