Thanks for your various comments, we are looking at many areas which overlap with your requests. no promises though.

One point the video bit rate has not been changed in the hacks, it already allows up to 12mbps out of the box. But this is dynamic, it depends on the amount of detail in the scene.

re 30fps I already answered that along with compression in the original interview.

Does that mean they're going to add the same functionality that otherwise you'd need to use the hacks to obtain ? such as the 100mb per minute files etc ?

I believe the bad flare issue is indeed caused by the silver ring and is easy to dupliate... in the photo below you can clearly see a curved shape flare which IMO is the silver ring around the lens (my N8 is orange).



If I simply place my finger to the right of the lens (seperating it from the light) you get this...


*my finger entering the camera lens to left is only to show HOW MUCH light is reflecting right there.....

Do you think if Nokia were or are aware of this would they see it as an issue or not?? Would they release future N8's with no silver outline?? Would they replace existing models or would that be far too expensive for them?? I guess it could put their long awaited flag ship N8 in a bad light(no pun intended)

I highly doubt they will do anything about it.... my C905a does the same thing and once your aware of the issue the solution is simple. A) try not to shoot toward bright light (ie, keep sun at your back) unless your intending to add flare to your image.. or B) just use your finger/hand to block the sun/light in those situations.... Not really a HUGE issue IMO

They most likely intentionally made this ring a brushed metal surface for a reason.. it probably brings in more light in low light situations as well.. which is a good thing i guess.

But from what what I have seen so far with Nokia, is they will delete any threads on their support sites which call them out or put them in a bad light.

Guys, I'm not very sure about this, but the way I see it, those excessive flares are a downside of the wide lens optics rather than that sliver ring around the lens!

Actually, physically, or geometrically, teh ring is bended away from the lens. This means it should reflect light away from the lens not vise-versa! At extreme cases, a light ray would be reflected with 0° angle, but never negative angle towards the lens..

This is how I see it..

And actually I find it really awkward for the team developing the camera to oversee this flaw if it exists!

And at the end of day, any camera, specially with wide-angle lens, will suffer from those flares at certain angles when facing a bright light source!
Of course, the question here is whether that ring is helping worsening the situation, but in my opinion, it should be rather helping improving the conditions.
And that finger-shading effect that helps remove those flares, is actually stopping excessive light from entering the lens rather than stopping it from refelcting off the ring..

About the position of the flares, it doesn't have to be on the side of the light-source, specially if the sun is that source..

Correct me if I'm wrong..

My two cents.

@mlife that photo with the flare is quite excessive. I have seen lens flare before but nothing that bad that's a design flaw imo that Nokia have not realised. Having to stick your finger in front of the lens is just crazy

I agree with false_morel, i dont think its a design flaw at all since the silver rim is pointed outwards from the lens. I dont see how it could reflect light back in.

I posted in the Satio vs N8 thread when i received my first N8 that it was more prone to lens flare due to its wider angle lens. Its a no brainer for me.

I imagine putting your finger or hand around the lens to shield it from excessive light is like using a car sun visor, or when looking into the distance on a sunny day you put your hand across your forehead to shield your eyes from light in order to stop the same effect with your own human eye. No ??

For me, i think id rather just not shoot into the sun or any other light source - which naturally a good photographer wouldnt do anyway unless he was going for an artistic shot.

a little off topic..

are any of you guys using any kind of screen protector for the camera lens? which also may further reduce glare..

I have a nice Nokia CC-1005 green silicone skin (is nearly an identical color match of my Green N8) which further indents the camera lens so its not touching anything when i put it down, so I don't think i really need any extra protection.

Was curious to see if you guys are using anything on the camera glass for protection..
