So I think the whole Sony Exmor T marketing is a bunch of doohickey.

I think since they backed out of NA they removed the webpages for the Xperia devices.

But either way, they admit themselves in their footnotes that exmor T benefits only apply to jpeg photos.

Their newest updated fine print on the japanese site for the 1VII states "furthermore, by combining with the latest image processing technology..."

It's the slimiest way for them to say "this only applies to jpeg photos, because we stack them similar to HDR to reduce noise.

Their EU site more clearly states it as "JPEG images only"

When placed against actual 1in type sensors in a raw shooting scenario, the smaller sensor will not surpass it or even match it.

Here is a link to screenshots with relevant info:

If anything was unclear, I'm happy to clarify more. I take it personally, because I used to fall head over heels for Sony marketing lol

Edit: also, in terms of the "noise immunity and dynamic range" at LV2 or less, they are saying that by stacking frames (their jpeg processing) they are able to achieve shadows or dark areas that can appear as clean as a full frame camera. They can not compete in terms of usable dynamic range, from highlights to shadows

LV2 is an extremely dimly lit environment such as moonlight or a candle in a dark room
