You must have a 'digicam' and not a DSLR. Nothing wrong with that. That's what I had (Sony F717) before buying the Canon EOS-10D, then Canon EOS-20D, and now the Canon EOS-5D.
That was a big change for me not being able to view my images on the LCD screen (or the TV!!!) until I shot the image. Only then I get the captured shot. So I have to look in the viewfinder for preview, and the LCD is only for review. I don't know of a good DSLR that has a preview feature. No biggie, anyway.
