Facts and rumors regarding the 16.28 Megapixel sensor in K- 5 II and K-5 IIs

F-pix · 09-26-2012, 08:54 AM

What is actually the facts regarding the sensor in the K-5 II and IIs? Is it a new sensor, or is it the same as in the current K-5?

Same sensor with the AA filter effectively removed.

Thread moved to the K-5 forum.

Thanks Adam,
Sorry if I wasn’t very clear in my formulation. I have understood the difference between the K-5 II and K-5 IIs, but what I am most curious about is if it’s the same sensor in K-5 II as in the original K-5, or if there has been any development regarding the sensor itself?

I don't think he is asking if the K5 II has the same sensor as the K-5 IIs. He wants to know it the K-5 II & K-5 IIs have the same sensor as the K-5. I thought I read somewhere that they have a newer version of the sensor. The press release refers to it as the "latest-generation" CMOS.

It's the same sensor in all 3 cameras AFAIK, though I'm sure the firmware has been tweaked, etc.

same sensor. different auto focus module....safox x.

just not to make it a deal..but I have read from web pages whome sell actuallu K-5 and K-5II, and it is really professional, and big in Finland(topshot) that sensor in K-5 has been tweaked and changed in KII. from 16.3 Mpix to 16.2 and it has better Iso handling too. dunno if it is true thou?!

The K-7 was producing a higher quality image than the K20D and they share the same sensor.

So I think even if the sensors are the same (And I believe they are), we should still see better images coming from the Mark II than the classic

some photokina pentax boss in interview said that K5II sensor is new...

There was a rumor thread from before the K-5II was announced that had some very technical tidbits. The rumor stated:

1a. Miniaturization of interconnection process
1b. Larger microlens for the vaster area available for light capture.
2. They took long time to tweak a newly-designed 16MP imager without LPF
3. They spent a lot of time to tweak SAFOX X

Obviously points two and three were correct, so I have no reason to believe points 1a and 1b are not valid. What this means is that the sensor is in fact different - less light-blocking hardware on top of the sensing elements could lead to better ISO and DR performance.

They don't share the same sensor, just sensors from the same family. The one the K-7 is slightly different, mostly to make (good) video capture possible.

Well, I'm just crazy then.
