The HM100 is the 1/4"-chip handheld camera.
The HM700 is the 1/3"-chip shoulder mou nt.

So could the shoulder mount be a HD251 with SD card slots. They mention using H&V pixel shift on the sensors, so unlikely to be 1920x1080 native sensors. I wonder whether the new 1/4" and 1/3" sensors can really achieve the kind of resolution we are seeing from cameras like the EX1/3. I hope they at least get close as I could really do with a smaller camera than my EX1 to replace my aging Sony HC1.

I'm also wondering about low-light sensitivity. I like my HD100, but it really wants a lot of light compared to my old PD150. I'd love to be able to ditch the on-camera lights when shooting indoors.

One of the reasons I was hoping JVC would jump to 1/2" chips.

the HM100 would be a nice B cam for the EX1/3! I'm curious about the HM700's "interchangable lens" by Canon. Could it be the EF interface or B mount like the EX3?
