I've been struggling with the SK17 picture quality. I've been very underwhelmed, the nr is very heavy handed and in general even under the best light conditions produces low quality pictures.

Then it dawned on me, there must be a picture fineness setting. Meaning, how much detail do you want the camera to capture. I had this thought after reviewing a number of pictures. None of them are greater than 1MB in size. A high quality jpg image will be up to 1.5MB in size.

Maybe Sony could add a fineness setting for the jpg capture?

A few other things I've found just by obervation.

Lowest ISO looks to be 64
Highest ISO 800
fastest shutter 1/1250

Note, not the easiest thing to get these values, as EV and sports mode need to be engaged.

this is the worst ever camera phone i ever had. videos are lacking in detail. we don't know if it will be rectified in the coming 2.3.4 update?

Yeah, not the best camera for non-bright conditions.
I installed an original gingerbread camera for some other Xperia device with the same sensor but modded to work for Mini Pro. And took some shots for comparison with the highest quality settings (Super Fine) on the original one. File sizes were about 30% larger but with no very little to no differences so i stuck with the Sony's one.

They're coming up with some camera tweaks for new update so maybe they'll manage to improve this aspect although i doubt it.

I hope they can come up with some improvements. Hopefully software can get better quality. The picture quality is even poor with very good lighting.

Something to note, the lens is rather small, I compared it to the C905a Exif data. the C905a is outfitted with a 6mm lens, the one in the Minipro is 4mm. That's a 33% difference in size!

I don't know the size of the W580i lens, it didn't come out in the EXIF data.

Maybe im not a demanding camera user but daylight photos look good enough for me, although they probably can be improved via software.

Only thing that i'd like to see improved is low light photos but i dont think software can help much there. Its much more dependant on sensor size.
We'll see.

You're right, at the end of the day it's the sensor size/quality.
I'm assuming the camera is doing a lot of internal processing. NR as well as compression. Hopefully, they can do something about reducing both.

As you say, if the sensor isn't up to the task, it won't matter.

Its a crap cam.
Arc got a way better cam, but its a cost/marketing issue... see? They want to niche ray,mini,neo,arc,play
And this shows on the pricetag/targeting ads..
Basic marketing.

Well its the smallest and cheapest of them all so corners had to be cut somewhere.
Theres also the segmentation of products that you mentioned but every single manufacturer does it.
We all wish it was a bit better but its not 'crap'. And daylight pictures are decent.

Edit: Check out this comparison. Load up mini pro and arc and you'll see that Arc isnt actually that much better even though its 8mpix and device itself is highend-ish. Also load up Galaxy Ace which has 5mpix, it blows mini pro and arc out of the water. Same goes for xperia neo. 2011 Xperia phones have had sup bar cameras it seems. They all have the same imperfections, not much differences between them. http://www.gsmarena.com/piccmp.php3?...&idPhone3=3619

Nice find! Looks like there are 2 main issues that make me unhappy with the PQ.

1: Is the noise reduction pattern, it looks to have a blotch pattern to me. It's not a pleasant constant grain like the iPhone 4.

2: Dynamic range looks pretty poor.

I think both of these could be due to the NR and compression algo. It would be nice if Sony would provide something better, or if it could be fixed via software.

It's a shame the test chart didn't provide better real world fine detail examples. I like to look at hair for this type of test and apparently that sample photo of the girls isn't helpful since the DSLR cameras didn't show good detail in that area.

However, it does give a feel for just how good of a job the camera can do.

Its a midrange/entry level phone ffs. Dont compare it with iphone4.
Its not on the same planet.
And a compression algo is indeed controlled via software. Same with nr. Stuff that SE finetunes with firmware updates.
Now, enjoy what you get for the money or buy the Arc S.
