Sassho, I've seen much better samples than that on Flickr.
Also the S4 Zoom had mid range compact camera quality that was confirmed by trusted reviews, phonearena etc, so the K Zoom won't have less quality so it is better than a cheap compact camera.

@northmonkey - Exmor RS sensor in K-Zoom is good , but has again strong noise reduction. Ofcourse this take down detail. Lens not a Best with this 10x Zoom. K-Zoom look's as funny toy , nothing more.

Of course picture quality won't be very good when zoomed in 8x-10x because it's at the far end of the zoom.
I don't think any Android cameraphone is better than this or even close. |

i don't think there's any significant or even noticeable difference between 2x, 3x, 4x ... 8x and 10x zooming. the zooming here is an optical one. there will be no noticeable image degradation between zoom levels. your concern regarding degrading image quality when zooming is only applicable on digital "lossless" zooming like the one employed by 1020.
maybe you'll just have problems with the shake since a small shake can be amplified as many times as you increase your zoom. i'm not sure how the k zoom's OIS will perform.

^Image not good and without zoom - blurry in lens ending. Maybe K-Zoom now is the Best android cameraphone , but stay too far from 808/1020/1520 camera quality. The price is very high from this image quality. |

Your right but quality can be affected a little at the far end of the zoom but what do you think about the samples?
I think it's a very good camera phone, probably doesn't have the image quality of the 1020 but has the advantage of real optical zoom and a more powerful xenon too from what i have seen. |

Compare K-Zoom with this old compact camera

Yes, there is ..
more zoom > smaller aperture > less light reaching the sensor > deteriorating quality
If there is one thing that the pureview zoom/cropping technique has, that is that it keeps the aperture constant at it's widest throughout the zoom range. So in the case of the 1020 its f/2.2 at 1x, 2x, and 3x |

i hope somebody does a shootout soon to prove/disprove your point.
from what i understand with optical zooming, there's less light going into the sensor in the sense that the light being collected is only the light that represents the specific zoomed in image. hence, it's not the full light an unzoomed capture will be taking. i don't think that translates to lower image quality. it's still way better than what "lossless" zooming does. optical zooming will always be superior to digital zooming. as what pureview fanboys love to say "physics always wins." the zooming lenses focus on a particular light source. they don't limit the light. they just get what they need to show a specific zoomed in image.

comparison between lumia 1020's 38MP shot vs a canon camera with 12MP. the canon's optical zoom shows better and sharper details even with the lower MP count. that's the power of optical zooming. 
from the link:
Our results show the benefits of zooming in with a compact camera over even the best-in-class smartphone. The Lumia 1020's digital zoom simply can't stack up against the Canon S120's optical zoom. The Canon can not only zoom in further, it also retains detail and sharpness better when zoomed in to its full 5X power.
Photographers and photography websites like ours will continue to debate the pros and cons of smartphone versus camera, but for now there's simply no contest when it comes to zoom.

Arguably The Best Android Cameraphone Ever Produced

The camera you quoted has a much larger sensor not to mention it's a "proper" camera, this is a phone and camera in 1. |

How can you actually say that when it's not even released yet?? These adverts paint an amazing picture of these products but the reality is never quite so great 
Phone?? What phone?? |

That's true but it should be the best android cameraphone, no other android phone has a bigger sensor, it's bigger than the S5 sensor and the same size as the Z1/Z2.
It looks like it's using the same sensor as the Z2 but it will perform much better than the Z2 due to Samsung being much better at software than Sony.
With the xenon flash and OIS and optical zoom it should in theory easily be the best android camera phone. |

I never said that one was better than the other, it just depends on the application and usage case.
In the case of smartphones the less movable parts you have, the better in terms of hardware reliability. The complex optics required for the traditional zoom lens are
1. heavier,
2. take more space,
3. more likely to go out of alignment in case of a drop,
4. edge sharpness is much harder to accomplish, there is distortions toward the end of the frame
5. mechanical noise during zooming, which sucks during video.
so that makes the "optical zoom is better for smartphones" questionable, and not a clear "winner"
of course, in terms of raw zooming ability they are better, which is why they are the best solution for large sensor camera such as DSLRs and mirrorless P&S designs.

You sound very assured.
Have you looked into satellite imaging and what kind of zoom is used for that type of application ? Think about how big the lenses and the hydraulics required for optical zooming and moving them would be.. and the levels of distortion at the far end of the zoom range ? No way.
They use HUGE sensors and crop into the images, which is where Nokia "stole" the idea for the 808/1020 system.
Now if we look into telescopes, its the opposite.. you have plenty of space and you can make them as big and as heavy as you want, which is why we use them here on earth, but not in space.
So, back to what I said.. it depends on the application, but it seems to me that if you have limited space, digital zooming might be better.
Now, is it better for smartphones ? Not necessarily.
Is optical zoom always superior to digital ? No.
