A follow up to my original post comparing all 5 existing iPhone cameras. This time I'm challenging all 5 iPhone cameras in 3 common low-light conditions:It was very difficult to get a clear image without movement with earlier iPhone models including the original iPhone and the 3G. These images look blurry and washed out with little contrast. The 3GS showed some improvement in saturation of color and sharpness. The iPhone 4 shows a marked improvement from earlier models in over-all noise levels, contrast, and dynamic range. The iPhone 4 still struggles with auto-white balance noticeable in the greenish tint on the chocolate cake photo. There is a huge jump in the sharpness, level of detail, and noise levels between the iPhone 4 and 4S. The ability to set separate focus and exposure in Camera+ on the iPhone 4 & 4S helped create a more balanced exposure. It's clear that the iPhone 4S's f/2.4 wider aperture lens coupled with it's newly-optimized sensor allows it to out perform all previous models in low-light.

Nov 7, 2011 schlaeps I'm always shocked at the jump from the 3G to the 4. Can't imagine what it must be like to move from the 3GS to the 4S.

Nov 7, 2011 Michiel I moved from the 3GS to the 4S. The camera was great but is now amazing!

Nov 7, 2011 trey Very impressive the jumps from each generation!

Nov 8, 2011 Rod hysted The 4S camera is wonderful, but can struggle to focus.

Nov 8, 2011 John My comment is: who the heck owns five (5) separate working iphones?!

Nov 8, 2011 ojeffmo Pretty cool stuff... for macro issues you can put this on your phone and it seems to work pretty well. I used it for one of my thesis projects. http://www.curecart.com/blended-502394-B005C3CSZA-067X_Macro_Conversion_Lens_Wide_Angle_Lens_for_Apple_iPhone_4_iPod_Nano_5_Camera_Phones_and_Pocket_Cameras_with_95mm_Lens
