There are not a lot of wide angle cameras available.
To my knowledge, there is no 3 megapixel cameras with a 28mm focal length.
There are 7 cameras - that have 7 or 8 megapixels.
So I have ruled them out.
That leaves 4 cameras:
Fujifilm E500, 4 meg
Fujifilm E510, 5 meg
Nikon 5400, 5 meg
Canon S60, 5 meg
None of them use SD memory cards.
The Fujifilm cameras use xD Picture Cards
The Nikon and Canon use Compact Flash Cards
Here is a comparison of specifications:
I take a lot of shots of the inside of houses and need to have a fairly wide angle lens. My current camera has a 35mm lens and is too "big".
I only need 3MP and I prefer SD card storage.
Any ideas are appreciated.
