It was just announced that the iPhone 4 will have zoom for the camera, but will this be real optical zoom, or will it simply be "digital" zoom? Digital zoom is so stupid - I can duplicate the effect of digital zoom by cropping the photo with photoshop afterward. Not only is digital zoom in effect the same a cropping a photo, but because the photo was cropped from the get-go, you have LOST information that you might have wanted. What if you "zoomed in" and took the picture, but mistakenly chopped off the top of your subject's head? That portion of the head was actually being perceived by the camera's sensor, so you could have had a complete photo, but it is now lost forever thanks to digital zoom.
Got a tip for us?

It was stated that the iPhone has a digital zoom. For it to have optical zoom, the lens would need to move out of the frame, and Apple wouldn't allow that.
A simple solution is to not use the digital zoom.

Well, I guess he said in the keynote. I could not sit through that thing, sorry. I tried Google and MRoogle to no avail.
Although it is hard to implement optical zoom on a mobile device, they managed to actually implement optical focusing, which really blew my mind. On my 3GS, you can actually see the little lens moving inside the phone to focus. Moving pieces, what a trip!

Optical focusing has been available in hundreds of cell phones for at least 5 years.
