Lets start with replacing the Sony H5 with either the H10, H20, H30, T200
You will be trading down.
The H5 has a viewfinder and Aperture Priority, and Shutter Priority. None of the others have those features.
If your wife uses any of those features she will not be satisfied with any of the replacement cameras.
Plus the T200 is only one year newer than the H5 (not a good upgrade).
Replacing the Sony TX1 with the Sony WX150:
I don't like that suggestion at all:
The TX1 is noted for producing excellent photos.
The WX150 uses the new Sony 18 megapixel sensor which is noisy.
Noisy means poor low light performance and photos with reduced detail.
More megapixel is not needed on a small camera and it reduces picture quality.
10 megapixels is just about optimum (and the TX1 has 10 megapixels).
Been reading all forums back for awhile, researching for 2 cameras, 1 for wife upgrading her H-5 if i buy one this year and 1 for daughter upgrading Sony TX-1 if I buy one. Things important for both, good pictures, good video, good sound, daughter smaller size, wife smaller size maybe got tired of all reviews and started looking at T3i but really wanted to get her something like sx-260 but never liked all the negative reviews, researced lots of sonys because she has 2 sonys figured it would be easier, never sure on hx10,20 or 30, need help on this, looked atwx150 for daughter and others but not sure. Researched sometimes too much and then not sure but every camera i ever bought kids and wife did love sony T-200 was a little tough though but still some good pics. thanks,
