Razec, what you're pointing out is absolutely not JPEG compression but just luminance noise from the sensor (with some noise reduction). When you're packing so many pixels on such a small sensor you get more noise and it simply looks like that. Adding more JPG compression would actually smoothen out those artefacts but you'd end up with less detail.
This image was taken with JPG compression set around 90, which is very high and very close to what DSLR's use. My NEX-5R (16MP) JPG's are between 3MB and 4,5MB depending on what is in the shot, and that is on a sensor and lens that can resolve more detail than Honami.
It's already extraordinarily detailed for a sensor this size with 20MP.

Considering that this shot was taken at ISO 64 it would have to be very noisy, but it looks like chroma noise is very low or very well controlled. IMO, they should lower luminance reduction and leave slight grain to retain sharpness and that film-like look. I think that many photographers would appreciate that.
Agree that this shot is very nice, but still needs some fine tuning. Maybe adaptive noise reduction.
Strange, my nex-5 can take shots that range from 5 to 7mb and if I use RAW's then after processing, most of the time, they reach 10mb all with 14mpix
All in all, I still think that it looks very good but needs some fine tuning. Curious how low light high ISO pictures look like and how high ISO good light shots look like.

Guys this sample photo is practically macro shot, and all camera phones shine at macro photography, what is really hard and tests camera quality thoroughly are landscape shots, and till I'll see such photo from Honami, can't really say much about quality, knowing Sony it won't be mind blowing

Doesn't matter if its macro shot or not, the processing is the same and this is what we're discussing right now. You can see that it retains high amount of details so if it can properly focus at infinity with appropriate depth of field for landscape shot then there shouldn't be any problem with getting high quality picture.
What sony should work on is eliminating this kind of halo that is visible on this particular picture, lower luminance noise reduction should help.

^^ If you're referring to the visible color fringing on the garmin logo as well as the bright reflective portion of the bike then I think the problem is on the lens, not processing, DSLR lenses usually come equipped with special coatings which reduces this kind of defect.

I think that this particular kind of halo comes from not fine tuned processing, you can see that especially on the garmin logo, sharp but not uniform if you know what I mean. From optical point of view I think there's everything fine, although can't judge that without seeing RAW's but JPEG's look good.

Actually the pre production samples that I saw from last time looked similar to this, even the way Honami's image noise looked like (which appears as a crisscross pattern).

well you crops are more then 100%
this is 100%
for me this is very good and much better then before on any other sony phone

^^ I wasn't cropping, I was just showing some problems with the lens/post processing. like that noise that appears like a crisscross pattern.

We need RAW data to judge what this sensor-lens combo is really capable of
