Darren_Birkin: Not sure I understand the comment about the X20 having better pottential for out of focus backgrounds than a camera with a larger sensor and larger maximum aperture. How does that work? You said it's counter intuitive which it is but you don't say why it is that way.
@mosc the concept of equivalent aperture is not easily explained as the concept of equivalent focal length is. For instance, an f2 lens on the X20 has the same light gathering ability as an f2 lens on a DSLR. However, that is not true for the depth of field factor. The crop factor plays a role only on the depth of field ability of a lens, not on its light gathering power.
duartix: Why the reviewer says there is little to pick between the 5 and 4s, I totally fail to understand...I mean... look at the first picture, it's pretty obvious:
The 4s has a lot more DR. It's screaming in the highlights whilst in the shadows they are pretty much close.
The 4s has also a lot of over-sharpening halos, look at the rails. Heck, looking at the buoy I even thought it was purple fringing.
Come on, if you don't spot these issues at first sight you shouldn't be doing reviews...
Well, I for one have replaced my iPhone 4s with a Nokia 808 Pureview 2 months ago and have never looked back. I am very happy with 808's performance as a phone. Certainly way better than the iPhone 4S in some key phone aspects for me (ie call quality, signal reception, battery life, Maps and GPS). On the camera front, the 808 blows the iPhone out of the water, both for stills and hd videos. Definitely it is an acquired taste UX wise, but easy to get used to. But if apps is your thing more than mobile photography or long lasting battery to power phone functions, than an iPhone or any android device is better suited.
