Question for Jan Crittenden Livingston re: new Panasonic AG-AC160 upgrade to AC160A

Hi;

Jan, the genuinely fine people at Panny Pro support are not sure of the answer to the questions below. I have purchased an AG-AC160 which will arrive next week. I would really like to keep it and pay to upgrade it to AC160A level (instead of sending it back to B&H for a refund and waiting to buy a "true" AC160A at a possibly higher price), but I'm worried.

Assuming that I keep the cam and then send it in and pay for the upgrade, will there be any lack of features in my upgraded AC160 and the "true" AC160A? I would hate to find out down the road that there is some subtle difference. For example, is it possible that future firmware upgrades might only work with a "true" AC160A?

My second fear is that the new "true" AC160A will have a better viewfinder eyepiece that provides more magnification for the EVT. I'm sure you are aware of the complaints, people trying DIY fixes such as sticking reading glass lenses in the eye-cup, etc. Any thoughts about this?

Thanks!

Steve
