24.3 MP Exmor CMOS sensor
Surely, facial recognition is a software application and nothing to do with the sensor?

Surely must be, unless someone has invented an intelligent sensor!

24.3 MP Exmor CMOS sensor
I think (as already stated) somebody rambled off the specs for a particular camera due to be released with this sensor... perhaps? either way... Pentax always seems to show up to the party fashionably late.... so if the sensor appears in next years Sony's and Nikons, then it will be 2013 to 5610 ...

24.3 MP Exmor CMOS sensor
I think I'd be happy that they were late and got it right than in time with all the others with 'advancements' that are only eye candy. From a photographers point of view Smeggypants^ got it right when he said better ISO performance was more important. When I was looking at the K-r a few days ago...

24.3 MP Exmor CMOS sensor
:lol:24.3 MP on APS-C is completely futile, it's beyond the resolution of any lens you can put on the front of the camera. Canon already hit that obstacle at 18 MP:roll: John Whenever you put a higher definition sensor behind a lens, you always get some improvements. The difference won't be as ...

24.3 MP Exmor CMOS sensor
Whenever you put a higher definition sensor behind a lens, you always get some improvements. You're more likely to discover the limitations of the lens in use which will more than offset any slight increase in resolution, I'm not sure I would call that an improvement. If they're going for 24+ MP the...

24.3 MP Exmor CMOS sensor
We are probably about at the APS-C limit at 16-18MP, using current technology. If it goes beyong 20MP then I pretty sure there will be problems with many of our current lenses, of all makes. 20MP+ sensors are probably in the realm of full frame cameras. By next month this could all have change...

By next month this could all have changed of course. Not unless they change the laws of physics, or use software interpolation. John

24.3 MP Exmor CMOS sensor
Would it cause a problem per se if the sensor exceeded the resolution of the lens? This already happens with many of the lenses we use. There are some advantages to more megapixels, making the bayer pattern of colour photosites finer for example. But I agree we are now at a point where ISO perfor...

Would it cause a problem per se if the sensor exceeded the resolution of the lens? This already happens with many of the lenses we use. I think it depends to some extent on just how much more the sensor exceeds the lens resolution. Pentax have already released a MkII version of the kit lens for ex...

Here is a read. http://www.luminous-landscape.com/tutorials/resolution.shtml When shooting at f/8 13mp is the max but if you shoot f/5,6 then 27mp will do well and for f/2.8 107mp So we aren't at the max yet, although this is the diffraction limit but surely there will be prime lenses that co...

24.3 MP Exmor CMOS sensor
It's a complex issue, but I'll quote from the conclusions of your link: Small format sensors may have surpassed the limit, this is, in most cases they are lens-limited in terms of resolution. This may well be so, and from the lens testing I've done so far I think it looks about right. As regar...

24.3 MP Exmor CMOS sensor
I read a piece over on pentax forums about why more megapixels (beyond what the lens can resolve) isn't a complete waste of time. I can't find it now but it did do a pretty good job of dismantling some of the received wisdom about the generally opposed move to ever higher pixel counts. But I woul...
