Originally posted by monochrome I get your point and I agree to a point. As I wrote above, whether the author knew it or not the iPhone is the correct device to choose for this kind of article because it is as commonly owned as the Instamatic was 50 years ago, so comparing iPhone and 5D would be akin to comparing Instamatic and Canon F1 or a Nikon F2. For certain kinds of images an Instamatic was remarkably competent - it was optimized to take the photos its target users (my grandmother) commonly took.
Believe it or not, street-stock economy car timed competition in a mall parking lot is a very big deal.
Autocross is an organized, Sports Car Club of America-sanctioned sport, with officials, rules, events, amateur judges, coaches, fans - sponsors - the whole she-bang.
Speaking of the Instamatic... my folks were using one (they gave me their "Brownie") until a friend got them a 35mm rangefinder camera (I forget which model of Yashica it was). The Instamatic never came out of the drawer after that. The difference was incredible.
In the comments section of the Ars article I asked about noise performance. All I got in answer was down marks (last I checked). I found the comparison featured only the good points of the iPhone. That's probably why I got marked down.
