Web Analytics RiceHigh's Pentax Blog: Possibly the Next Generation Sensor Used in the Q-02 (if Any)

Possibly the Next Generation Sensor Used in the Q-02 (if Any)

Sony IMX118CQT, 18.47MP/24fps BSI 1/2.3" CMOS sensor, next generation of the IMX078CQK 12.4MP that currently used in the Q:-

So, the pixel count race has not yet stopped actually and now those small DC sensors continue to grow! If there is going to be a Q-02, this possibly the new sensor that fits the same image-circle size and it will have even a higher pixel count than the K-5! :-o

In reading the Image Sensor World blog at the same time, I've seen today's headline is about the unusual serious highlight blooming of the Fuji X10 sensor, see what DPR has investigated and found:-

Oh, it's really terrible! :-{ Now, I am really satisfied with the weaker highlight preservation of my K-5, as there exists other camera on Earth which has even far more serious problem of this! :-o The above test shows that the new firmware is not going to help. It's really sad after all! At the end of the day, I am still asking the same question: Is firmware going to help for eliminating a *hardware* issue? >:-|

Relating to Olympus problem how the hell did this orb problem was missed by QC department?This is clearly afecting highlights and easy to spot.You don't need engineering diploma to see those...

I have the x10. though I don't use it at night and getting the bloom effect.. makes me worried about the total QC of Fujifilm. They had issues with their X100.. now X10... makes me wonder if there could be any for X-Pro1. After all, they are selling this as premium cameras so they really have to solve these issues.
"Now, I am really satisfied with the weaker highlight preservation of my K-5, as there exists other camera on Earth which has even far more serious problem of this!"

This is what happens, why people diss on you. Sometimes your blog is really useful, sometimes it really presents just facts, and often it just makes shxt up like when you accused Pentax of not coming forward with the stain issue of the early K-5's.

There is no "highlight retention" problem BS with the K-5. Read the F. manual. Set the camera highlight priority and done. Or learn how to use the tools you have for photography and learn what it means to expose to the right.

Highlight priority does not adjust the exposure on Pentax, and the shadow lift is quite crude really and too strong as well.
Nikon ADL works far better as it's at least somewhat intelligent and adjust the exposure and tonal curve depending on the setting and scene. Sony's DRO is mostly shadow based. Canon's has got a bit better but it's still not as good as active D lighting.

Worse the shadow lift in the Pentax models screws up the images to a degree with some weird effects and hue shifts.

An on topic comment ...

Note the sensitivity of the Sony IMX118CQT sensor is 1054 digits that's about about 1 stop down on the IMX078CQK 1437 digits sensitivity i.e. it would perform one stop slower in ISO. That doesn't seem like a smart move for this sort of camera.

The saturation signal though is about the same (which is interesting as the pixels are smaller).

You might hope that there is a 12Mpx Sony Exmor sensor using the same technology that hasn't been annouced yet (perhaps just before photokina). Sony do have an type 1/1.7 CMOS sensor that has yet to get an English datasheet that you might see in the Ricoh GRD 5.
