Yes I am.  Quite a lot.

Re: Resolution of my Nokia 808 (mobile phone)

Okay...
   Was the Nokia pic of the doggy posted to demonstrate:
1.) nice and smooth ?
               or....
2.) a bit harsh and busy?
  Surely it can't have been posted to demonstrate
comparable accutance........

Oh it sure can, dear fanboy, and that´s why it´s so fascinating, just put your glasses on and click on the second image and than click on the 1:1, OK?

Re: Resolution of my Nokia 808 (mobile phone)

Does this mean that a cell phone can almost reach medium format quality?

Looks like...

About the same resolution as my CP950 Nikon from 1999..

Not quality in tonal/dynamic range, but in resolution (detail level) yes. And this post was about resolution. Nokia 808 has 40Mpx on relatively "not small" sensor and using this oversampling reaches  excellent results, especially at lower resolutions using pixel binning. A very good phone for Foveon-detail lovers (me)...:)

Hi Petr,

The problem is that you really can't tell from the closeup you posted much about real resolution. The Nokia 808 is by far the highest resolution cell phone camera available, and as you say does very well with the reduced size such as in the 8 megapixel mode by binning, but even a three megapixel resolution camera can look "very" good in extreme closeups - here's an image from my Nikon CP990 from many years ago as a sample: Click on Original Size if image doesn't show...

Nikon 990

Best regards,

Lin

Re: Resolution of my Nokia 808 (mobile phone)

First image is the whole original image reduced from 40Mpx as reference, second is crop from the same original image, not reduced. It´s not a closeup, it´s a crop!:)

That's freaking amazing.

I don't think you're clear on the concept

Thanks for the image. Demonstrates the quality of that cell phone.

But, hey, even the original image is a "Close up."

There is nothing in the crop that isn't visible in the larger shot.

Here's an example of what is meant by the term, "Resolving Power."

The first is a reduced version of the entire frame, and the second a 100 percent crop.

So, as the above shows, it's not just a question of enlarging  what is visible, but "resolving" what is not.

Again, thanks for the Nokia demonstration.

Dave

But ... the second image (the crop) at 100% looks horrible. Sure - there is lots of detail. But ... its also such a mess. The hairs looks strange where they are crossing. The nearest hair is thinner when there is something behind it.

Just took it today for curiosity sake did not expected to see cable from plane to banner and prop. Could not see either with my eyes.

This picture is not in particular sharp. The cable is at least 3-4 pixels wide. Any camera could have managed this. The reason why you see the cable is that the sky is very even.

808: resolution very impressive, DR and noise not so
1

Hi Petr,

I (somehow) agree with you. The sheer resolution of the 808 is mind-boggling considering how small the sensor is and that this is a cell phone camera. I looked a lot on dpreview's 808 studio scene and I am seriously impressed. If you only consider resolution: the 808'er output resolution is more impressive than the DPxM output (given the constraints!).

That's why I think all that focus on resolution alone as single measure of image quality falls a bit short. The 808's pixel quality is obviously not very good (but there are just soooo many pixels), the dynamic range is very very poor and the 100% images are quite noisy (which was to be expected).

I guess it would be possible to squeeze the 808'er sensor and optics into something just a bit large than a lighter. Now add an automatic multi exposures blending mode too overcome noise and dynamic range problems (works on static scenes only but ok)... wow!

Cheers

Joerg

It is actually 1 to 3 pixels on the photo in real life it is way smaller than pixel size and just for the laughs (directed at me) here original saved at half size with SPP settings set to X3F

camera was on manual and i did not have tme to change settings

DP2M vs SD1 & 30/1.4 = insane
1

The 30mm f/2.8 lens of the DP2M is insanely sharp. Take a look at this comparison  vs. the Sigma SD1 and the "old" 30mm F/1.4. It's mind-blowing how sharp the DP2M is wide open.

For quite some time the speculation has been that a very large pixel count can equal Foveon.  Looks like this is true.  I guess a 45 megapixel APS-C sensor would fully equal the Merrill across the ISO range.  This would include less performance above ISO 800, same as Merrill.

If this ever will happen, it is going to be a few years, and by then hopefully Sigma will have improved upon the Merrill.
