Rumor: Panasonic GH2 to use new 'dual exposure' sensor

Supposedly this new sensor technology could increase the effective sensitivity of the Panasonic sensor by a factor of 4 and will be implemented in a GH2 slated for September release!

Hi Steve! I think you've hit upon the killer three lens combo there, at least for my needs. The GF1 is great as well, though I've gone for the G1/GH1.

As you alluded, PMA is right around the corner. There is also reason to believe that Panasonic may announce new cameras at Focus on Imaging in early March (source). However, I very much doubt that we'll be seeing a GF1 upgrade soon. More likely a G1 replacement in early March, a GH1 replacement later in the year, and a GF1 replacement later this year or early next.

 

Sensor improvements are typically very slight, incremental changes. Look at DxOmark's data, for example, and you can see that Canon's latest Digital Rebel 550D (pre-production) has just about a 2/3 stop high ISO signal to noise advantage over the original Digital Rebel 300D which preceded it by 7 years. There's a lot of talk from various companies about 1-2 stop improvements in a single generation, but they are almost always referring to improvements in noise reduction processing for in-camera JPEGs. I like the fact that Panasonic is thinking outside of the box.

 

Yep, that's another good example of the kind of innovation we need, applied to the smallest sensors. Fuji did some really nice innovating with their DSLRs and dynamic range some years ago. Good to hear Panasonic talking tech!

 

Sadly, it seems that this Panasonic sensor technology is being developed for a 2.2/3" sensor and applies to video capture. EOSHD.com seems to have botched the story completely in associating it with the GH2 .
