Yes, the X20 you recommended in post 15, I wasnt referring to the crop and I explained that was a max figure I came up with in that same post that would still be usable unlike a ISO1600/3200 x20 shot in low light.
I dont, were just making points for the OP to consider regarding 35mm and you may want to lock yourself in a room with your OCD distortion issues. Newborns dont stay the size of newborns forever, thats a fact. The link of the 6 month old is what a lot of people would consider fine especially considering the cost of the camera and the performance, not everyone minds distortion and shoots at 200mm like you to achieve zero distortion.
I have recommended a few decent cameras in his budget and for his requirements, what have you come up with? A compact that will offer zero shallow dof and that will be useless indoors in low light. I guess we can agree to disagree. Its good the OP is hearing the + and - of something like the x100 as our disagreement may help him out even more.
