I'm at Photokina 2012, as you may have noticed on the site
and in the forums here:
There's SO much to see and look at and more importantly TRY, that I think even if I was here ALL week I still wouldn't have covered it, or had time to upload it to ePHOTOzine. I guess that's why we're trying to publish the most interesting stuff first, and get what you want to see, and find out the information you want. We've asked in the forums, and asked on facebook, and have had some interesting questions too.
I think this year is really quite interesting, as it seems like companies are trying new and innovative things more than ever, for example the new Olympus PENs (EPM2 and EPL5) are going to be shipping with FlashAir cards, so you can transfer the images straight to your mobile phone, so as long as the card is in your camera, it has built in Wi-Fi.
Lenses are a big part of the site, and this year at Photokina, with everyone from professionals (eg http://www.damianmcgillicuddy.com/ ) to amateurs to point and shooters getting into "Mirrorless" cameras, it's certainly getting a lot more interesting.
Companies such as Carl Zeiss, Voitglander, Schneider Kreuznach, Sigma, SLR-Magic, Samyang and others are all getting involved, with new Micro Four Thirds or NEX or NX lenses. Of course there are new Digital SLR lenses, but in comparison there seem to be many more new lenses being announced for Mirrorless cameras...
It seems like the Mirrorless cameras are appealing to compact camera users who want quality and speed, as well as professionals who want quality and speed, and also want the benefits of a smaller system. And with the choice of lenses getting bigger and bigger, you can see why the cameras are so popular, and why it's one of the main areas in the industry that is seeing strong growth.
My (somewhat pessimistic) opinion is, that if you're not involved in this growing camera market, then you're not likely to be making much profit, and it could have seen a totally different story for big companies like Kodak if they had got involved much earlier.
