Apple - What are the shutter speed and ISO ranges for the iPhone 4S camera?

You can scrape that information off photos on flickr taken with an iPhone 4S:

Here are a few examples of extremes. The dark end seems to show a max ISO of 800 and max shutter of 1/15, which several dark photos agreed with, and none of the ten I looked at went further, so here are two examples:

800

800

Looking at very bright photographs, I saw a few claiming very high shutter speeds (1/9259 and 1/2600) but none of them matched the same exif format for the shutter speed field as the rest of the iPhone 4S photos I reviewed, suggesting that these fields were modified in post processing. The lowest shutter speed I saw that matched the format of the other 4S exif files was 1/1842, and the lowest ISO was 64:

64

This should answer your question for highest and lowest ISO, and highest and lowest shutter speed. Keep in mind I only sampled a few dozen photos on flickr, it's possible I missed the ends of the ranges.

A random sampling from the "interesting" section, showing the mid range of shutter speed and ISO combinations:

Shutter speed ISO

0.008 sec (1/122) 64

0.05 sec (1/20) 200

0.008 sec (1/120) 100

0.002 sec (1/550) 64

0.025 sec (1/40) 64

0.002 sec (1/464) 64

0.004 sec (1/242) 64

0.042 sec (1/24) 64

0.059 sec (1/17) 800

0.067 sec (1/15) 640

0.006 sec (1/170) 64

0.067 sec (1/15) 640
