Price is driven more by market factors than individual component price.While I don't know the exact cost relation in a body, I tend to agree.
The companies that produce ff dslr bodies are working like a trust and only release high quality, high cost ff products. Once someone releases a medium quality ff body at a budget price because it's possible nowadays with large sensors getting easier to produce, the deal's off and we might see aps-c pushed down to entry level and ff becoming the standard amateur format. At least that's what I hope.
Yes, exactly. I have said this same thing on other forum posts relating to the future of FF sensors. Mirrorless is eroding out the bottom end of the dslr market. The only place left to go is upscale. Not necessarily in price, but in features (yes, there is a weak linkage there). But for canon to continue to compel people to buy entry level dslr's, they have to offer a reason to do so over a competing mirrorless system. Now for the savvy, this is easy, they can see a clear upgrade path from an entry level dslr, where the path is maybe not so clear for mirrorless. But most entry level buyers are not that savvy. So they need other reasons to buy a dslr. FF could be the answer to that question. I know FF isn't that answer to all image problems, but it could be a compelling reason for many buyers to go dslr instead of mirrorless.
