Split screen technical explanation

Why not buy from B&H who give you 7-10 days to try the camera -- and give you a great price?

I'll be in LV next week and I'll try leaving it in the sun for an hour and then shoot as I suspect if there are is any temperature issue this should expose it.

Now I don't think it will be a CCD sensitivity -- although they likely get hot. It is most likely the 6 A/D converters. One hopes each L/R pair is in one chip to minimize temperature differences.

Of course, we need to keep within JVC temperature guidelines.

Steve... see if performance is affected by having the camera operational for an extended amount of time.

It looks like we have a good explanation for the SSE on another thread.

That's quite amusing Robert. Seriously it meant neither. I apologise but by temperature dependent I meant some cameras (not all) are not being properly set up to operate without SSE over the whole expected operating temperature spectrum for the camera. My bad - I didn't bother to explain - I was running short of time.

During the setup process, the the ability of the circuits to balance both sides of the screen is supposed to be tested over a range of operating temperatures - from here on in I'm just guessing - if that's not done properly the camera may past QC in the factory but not in the real world.

It does not mean that SSE may be more or even less prominent in hot conditions or cold conditions, although I wouldn't rule that out. Steve - it may even mean your camera works better in hot conditions, although the ambient temperature would probably have to be pretty high to make a difference to the operating temperature of the circuit. I do know the JVC engineer was complaining that many cameras in the latest shipment had not been set up properly and therefore he was rejecting them.
