wide-angle lens digital camera needed.

I have a Casio Exilim whihc is good but I need one to take wide angle
pics as when taking a pic of a small room but to fit most of it in.
Will this one below do the trick and if not can anyone recommend one?

thanks

No. You need a 28mm at least and maybe with a wide angle converter to make
it 20mm

Kodak do one and nikon plus richo G5 or 4 at a good price

 

A 28mm lens (or the digital equivalent) will give an angle of view of
approx. 65 degrees. A 20mm gives approx. 85 degrees. If you want 90 degrees
you would nees an 18mm lens.

You should be able to work out roughly what angle of view you need depending
where the camera will be in the room and how much you want to cover.

Alternative - shoot multiple images with the camera you have and stitch them
together with one of the stitcher programs.

 

Also the Canon 850is, at a bit over £200. This has a 1600 iso setting and
with image stabilisation letting you hand-hold at about 1/8 it will work
without flash in pretty dark places.
