Justtimthen: Can't believe the filters have been losing that much light! Real glad that Someone's on to it though.If the intensity of light onto the sensor is doubled I wouldn't be surprised if the end result looks even better than 1 stop particularly under the dimmest lighting conditions.It will gather more light without decreasing DOF which in some curcumstances maybe very desirable so I think this is pretty big. Well done PanI
By their very nature colour filters absorb light of the wavelengths they do not pass. So (simplistically) green absorbs blue & red, red absorbs blue & green etc. This means approx 50-70% of the light falling on the sensitive areas of the imager is absorbed and wasted.This diffraction technique deflects the "unwanted" colour onto an adjacent pixel. Rather than being absorbed it is still used to create the image.It is unusual for this sort of thing to be announced unless it has been implemented in some form. Hopefully we will see it in a product in a few years.
To me this camera seems finally to be fulfilling what I want from a digital camera. Small size, well built, good handling and decent image quality. (It isn't going to be any worse than the G3). DSLRs have nearly all been too big in my opinion. I was a long time OM2n owner. (I also loved the Pentax MX).
The image quality will be good enough for nearly all purposes, yes it will be a little behind APS-C and further behind FF. It remains to be seen how well the continuous AF works, which could still be a limitation in some circumstances.
I think the advantages of an EVF outweigh the disadvantages most of the time, and this is a further improvement. I used an Oly C750UZ for many years. It had a very poor EVF, but I got used to it and miss some of the functions on my current DSLR.
BetaHal: What about other aspect ratios than 4:3? I've become very fond of 16:9, as it lends more space for scene composition, and I'm sure that many of you will miss 3:2 and 1:1 too. What's more, those aspect ratios are supported by the G3/GX1 sensor, so it doesn't make sense not having them in the EM-5.
The oversized sensor is only on the GH1 and GH2. This is exactly the same size as the G3/Gx1 sensor.
studio67: Nice camera, but where is the external microphone connection?
