Hello everyone!

I am just brand new NL820 user, a little bit disappointed.

I enjoyed my Lumia till the moment I have noticed it makes horrible pictures.
I am almost 100% that the lens distortion is much to big.

I send it twice to the customer sevice in Poland, but they claim, that everythig is ok wit it.

I need your help and I would like you to do me a favor.

I did some test on this page:

and this is what came out (see attachements).

You can easily see that straight lines are not straight.

Could you please, do it on you Nokias and post in response. Just make some pictures with this .jpg fillingo 100% of frame, and you will see ist he lines are straight or not...

I would like to check if it is normal in NL820 or this is only my problem.

Kind thanks

This is normal, considering the camera has f2.2 aperture size, it will create distortion but at minimal. If you can take other photos other than geometrical shapes and lines that will only show up straight and symmetrical at a distance, then you'll be fine.

Without use using complex optics, this is difficult to correct. Even with proper optical design, there will be spherical distortions on phone cameras. That being said, the camera on my 810 was so bad, I switched to a 720.

This is normal. even 2000k obtics will suffer from this problem.
I think the aperture isn't the problem here. The focal length is doing the bad thing. Because the 820 has a wideangle lens you can not expect any better. I even think the distortion is quite low compared to other cameras( doing photography)

To please you. Here is a picture of my 820WP_20130602_001.jpg

It has nothing to do with Nokia or the 820. It's pure physics. You get distortion if you have a wide angle lens.
And as i said, the distortion isn't that bad. You shouldn't even see it when taking pictures of people. Look in the gallery to see some pictures taken with the 820 http://forums.windowscentral.com/nokia-lumia-820/209942-pictures-videos-taken-your-820-a.html

I compared several pictures with iphones and samsungs and the pictures really can keep up. Most people dont know how to take pictures and the 820 is a phone less helping you(ip5 gives often better results, but the camera is very limited in terms of creativity ).

Yes.
Overall camera is not bad.

But I really see some distortion, when I make photos of people.

I did not have this problem in my iphone 3, and iphone 4 and htc desire hd, even samsung galaxy ace...

I'll live with it. For a while :)
