As most know I work at Cars.com and edit the blogs there. That means I do a lot of snapshot type photography because we have a staff photographer who handles the official shots. I just take stuff for my notes or the blog. With the wife's new iPhone 4 I decided to see how it handled a car and compared it to my Canon G9 which is pretty good in terms of point and shoot as well.
The shots below are all in the same order. iPhone 4 first, G9 second. If you can't tell these have gone through no editing.
So as you can see it certainly won't replace my G9 in most circumstances and it really doesn't replicate the colors as well as the Canon either. But it still outdoes the 3G and I think in a pinch it will work. For now I'm still packing my G9 for trips.
