I think wrong, but KT says GH2 sensor in Oly

I wanted to know if, similar to the Panasonic sensor in the GH2, you could use other aspect ratios such as 16:9 and 3:2 without losing resolution. The answer I got was "yes." All but the 1:1 aspect ratio. If this is true (and I have no reason not to believe it) this will make me happy.

I find this hard to believe. IF true it would be great though.

Considering nobody else has mentioned this, I'm gonna guess he's mistaken for once.
 
The GH2 sensor is actually an oversized 18MP sensor. You get to choose several crop modes on that sensor which result in up to 16MP of usable resolution at any one time.

The Olympus has a single aspect ratio 16MP sensor which appears to be similar to the one in the G3, not GH2. However, I don't think it is identical to the G3 sensor as there are slight differences in effective and actual resolutions.
 
That would directly contradict the conversations we've had with Olympus.

So what KT cleverly asked, and got as an answer was:
I wanted to know if, similar to the Panasonic sensor in the GH2, you could use other aspect ratios such as 16:9 and 3:2 without losing resolution. The answer I got was "yes."
Which if correct would imply the GH2 sensor (and if correct wouldn't be an error on KT's part, rather on the Olympus rep talking to him.

I wonder if the Olympus rep was confused by this, from the Oly specs:
RAW: Aspect ratio is recorded as Exif data, JPEG: JPEG image is produced based on the aspect ratio
Which means of course that if you shoot a "cropped" aspect ratio no data is thrown away in the RAW file, it is still there if you want to change the aspect ratio in the RAW converter.

I suspect if it was truly "multi-aspect" like the GH2 they would have marketed that feature.

IIRC, Panasonic has said they were not sharing the multi-aspect ratio sensors (GH1 and GH2). I may be wrong about that, so thanks for the info.

What part directly contradicts said conversations? tkblsc made a few different points so it's not clear which part you were referring to.

Bottom line: is this or isn't this an oversized 18MP sensor like the GH2?
 
Specs for the 3 cameras:
Oly 4608 x 3456
Gx1 4592 x 3448
G3 4592 x 3448

So the Oly is a 16.9 MP sensor with 16.1MP output.

Who made the sensor????
 
Probably all that is different is how many edge pixels they are deciding to use. We've already seen this level of variation between the Olympus and Panasonic uses of the old 12MP sensor:

E-5, EPL1, EP3 - 4032x3024
G2, GF3 - 4000x3000

It still seems most likely this is just the GX1/G3 sensor.

1. Someone made a mistake in copying

2. Panasonic not using quite all of the pixels actually present on the sensor for some reason and Olympus choosing to use a few more.
 
I assume that he meant to reply to the original suggestion that Olympus used Panasonic's GH2 sensor. Like others I strongly doubt that is the case. 16.9 MP does not match any existing sensor, so the only reasonable conclusion is that Olympus has developed a new sensor with characteristics that are fundamentally different from the G3/GX1 or the GH2. Maybe it has fantastic dynamic range! Then again maybe it doesn't.

Like someone else said, the extra 0.9 megapixels accounts for sensor-shift during stabilization.
 
Every digital camera uses less than all the pixels on the sensor. Including those from Olympus.

Bokeh is the aesthetic quality of the blur in out-of-focus areas of an image, or the way the lens renders out-of-focus points of light. Bokeh is not the same as depth of field (DOF).
 
Does that mean the E-M5 uses an onboard ADC?
That would directly contradict the conversations we've had with Olympus.
