ExpoDisc vs LCC for lens calibration and white balance

interessting. With Phase the Contax doesn't show the exposure mode.
I have some questions about Sinar backs that I have no clue how to answer:

- What if I buy a Sinar back, but Sinar goes out of business. Are there places which repair such backs?

- Does anyone have experience with insurance claims on a broken back with no support

- How often do backs fail?

I am leaning towards buying the back in any case, but I would like to have clearly in my mind what the consequences are if it fails. The situation would be quite similar to buying a Kodak 645 Pro, I think.
You should probably email Sinar and ask them directly. We could only speculate. It would be nice to think that in a worst case scenario like Jenoptik choosing to stop production of Sinar gear and close that company that one of Jenoptik's other divisions that manufactures digital imaging like medical or aerospace could service the back, but maybe that is wishful thinking.

Having said that I think there is little that can go wrong with a single shot back because there are no moving parts in it as far as I know. It would become an issue if there was an internal fan that failed or if you scratched the glass or something else that seems minor but would render the back unusable until someone fixed it.

I don't know but I assume within the 3 years of warranty any solution would be offered by Sinar. Too, in such a worst case scenario a tech support would be established for some years (as always in these cases). After that... hard to say. But the 3 year warranty is really not bad here. And none can promise that one of the others player is still in game in 3 years...

I have the ExpoDisc from a couple years ago and still carry it but stopped using it and have been using the C1 disk. This thread has me thinking of removing the ExpoDisc it from my bag and selling it as I've been very happy with the C1 disk.
