hi

are there any difference between quality of shots due to "Carl Zeiss " lenses with N9 camera module and others 8MP with normal lenses snappers (eg Samsung galaxy SIII or Htc one X or S)?

thanks

Carl Zeiss is fairly well know for making very high quality glass... While this will help with image quality, it dosen't mean a Zeiss lens will produce better pictures than other cameras.

Lots of variables, but, I've always been a fan of Zeiss glass..

In case of phones they don't manufacture the glass. They only licence their name if the glass meets their quality standards. It's like a certification of some kind. Notice that the N950 teaser video has carl zeiss branding for the lens but the actual device doesn't. I doubt that they changed the glass manufacturer, they just didn't need to pay for the cerification of a dev device.

I might be completely wrong but I think it is Carl Zeiss licensing lens designs for mobile phones, although they may produce lenses for top mobile phone cameras, in addition Nokia exclusively might use the label "Carl Zeiss"?

I saw a video about this! its not even glass! they use plastic lenses for mobile phones!! but like you say its certified or made by Carl Zeiss!

while i haven't tried the sgs i am a fairly experinced photographer.
The common approach for compensting a low quality lens or sensor is via the in camera processing. A picture can be blurry and noisy, but a strong correction can make the average user to think the picture is "good". Oversharpening and boosting the color levels is quite common with high end cameras like canon.

having said this, i am very pleased with the n9 as my carry on camera. The pictures are sharp with lots of details and the processing is decent.
Nokia has a tradition in this regard.

Yes but acrylic is actually more transparent than glass so its better for a lens and it can be mass produced more cheaply

I think the first phones with carl zeiss branding were sonyerricssons and cybershot se's had that branding until recently, but I may be wrong. Lg had schneider-kreuznach branding (spelling may be inaccurate)

I'm not saying its a bad thing! I heard they also have to place the lens a lot closer to the sensor than you would in a normal camera!

It's accurate. There's also Schott glass.
