Your examples do not really test the DR limits of the 70D. You need really deep shadows for that. The read noise is additive, not a multiplicative noise.

Try night shots.

Totally agree. I don't know what op was trying to show with a bunch of ISO100 samples.

Often Canon gets bashed for poor DR at low iso when lifting shadows several EV. These samples are low iso with lifted shadows and demonstrate that actual results are what matter.

They do no not have deep enough shadows to allow you to test the limits of the DR. I do not know how to explain that to you in a different way. If the signal is above a certain threshold, you will not see the difference.

Surprisingly, technical tests are not God's word. Not always, at least.

Not surprisingly, random tests by people with random abilities to understand the technical stuff are a waste of time.

There are folks who see DXO ratings and claim "Canons are 2+ stops behind Sony sensors in DR, therefore their DR must be poor". I think these claims are unfair. Just that.

This has been discussed and demonstrated here to death. What is unfair is for you to ignore what I told you a few days ago, and to waste everybody's time.
