Raist3d: Richard, something is not quite right with this explanation of the high res mode. We were just discussing that over the m43rds forum and the point was brought forward.

Think about it- if you are capturing full color in a spatial position, that gives you an original "Foveon X3" type file of 16MP. If you shift a bit to then do the 4-position dance again, that at best gives you another 16 MP file. So the total is really 32MP, not 64MP, or even 40 MP.

My guess here is that Olympus is doing a clever analysis that gives them the near full color data and bump up to 40 MP. Makes even more sense why it's 40 MP and not 64 MP. The 64 MP file does not seem to me would be full spatial resolution. It also keeps color moire at bay.

That's what I meant by "clever" - as in an algorithm, a process etc. involved. Nothing more. Something has to give and like you said, there has to be an interpolation of some sort because two true color 16 MP images will not yield 64 MP. Some holes or some spatial resolution has to be filled.

But certainly they have a lot of data to fill it in. Olympus apparently said in an interview according to their own R&D, they felt 40MP was about the reasonable detail they could get from the data, not the full 64MP. Which makes sense given they are really doing 32 MP samples, not 64 MP samples.

My point is, the dpreview explanation seems to be missing something even they did a good job illustrating the shifts.

@J A C S - certainly the person I am replying which wasn't you, mentioned DR. Certainly other people who replied here, which were not you, were talking bout DR/Dynamic range. So yeah, looks like *YOU* are replying in the wrong thread :-)

Ivan- there's no need to agonize. One can simply accept that the dynamic range- per what Canon said, is sub par to Sony. That doesn't mean the camera or new Canon sensor is useless. Some people take this personal for some reason, it's just a simple data point. I was not suggesting you can't do photography with the Canon.

@srados - that's not dynamic range- that means you are not using a good raw converter or know how to use one :-)

We were talking about Dynamic Range. If Canon asserts it's about what they currently have, that, by definition, is sub par to what Sony has around (Pentax, Nikon, Sony).

BTW, none of those shots are high-Dr situations. The studio shot you can clip as a photographer where you want by exposure. The other landscape-building shot is hardly high contrast. And the last shot looks nice but again, not exactly a high contrast bright vs shadow situation. That's what DR is.

Note that, that is different from a benefit from the resolution, particularly resampling down. The last shot in particular looks impressive. But that's not DR. that's something else.

Well it's really simple. Canon says it's about the same as what they currently have. What they currently have, is sub-par to Sony's sensor. It's really that simple.

Raist3d: Any word if the camera sensor has an AA filter or not?

thanks.

That's what I would hope, but those jpegs look a bit too smooth to me- of course maybe default noise redux. If it has no AA they should be mentioning this. I don't see it mentioned.

Mike Hiran: Geez DPR what's with the snarkiness in your news release?!

Instead of taking a view that this is great to add another player into the full frame segment that has a history of good ergonomics, build quality and user interface, you take the view that it's bout f***ing time Pentax came out with a full frame camera.

And the impression you leave in your article is that Pentax promised a full frame camera 14 years ago when it was just showing a prototype.

Whether this camera turns out to be great or not, it should be viewed as a positive that customers will have more options. But placing your own emotional baggage into this news release is just a cheap shot. As if you would know what it would take to have a camera company (let alone a profitable one) make a competitive camera in a crowded segment - your impatient and entitled tone shows your ignorance in understanding the camera market.

Mike- I think the sentence you pointed out is a fair point. I don't think the "payers of Pentaxians" line is out of line though :-)

I just took it as a joke. If you have been in the pentax DSLR foun long enough you would understand why it's funny. (Disclosure: I have and love the Pentax Q. Still want a very fast Q mount prine for it )

In reply to:

Mike FL: Where is the D750 sensor exactly come from?

I can't agree that the current Nikon 1 Aptina is better at high ISO than the Sony sensor. And definitively not in dynamic range. The Nikon 1 sensor excels at having PDAF AF, and a fast electronic shutter refresh rate, and no AA. But the Sony sensor is superior when it comes to key IQ image aspects.

Horshack: Very nice follow-up on the flare issue Rishi. Ever since you started contributing to the editorial content on the site the depth of technical information has increased markedly. I just wanted to say thanks and to let you know your contribution hasn't gone unnoticed.

I agree- very nice Rishi.

photo perzon: Does the flash tilt up to the ceiling for bounce?

I looked at the design again carefully. Sorry Photo Perzon, and sorry everyone else- it sure looks like it could tilt back. For some reason the first time I saw it seemed more like one of these Olympus e-620/E-30/Pentax K-5 designs. Me bad.

Sorry everyone!
