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

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.

ISO100 pushed even, say, four stops is only ISO1600 equivalent.  I have no idea why people are gaga about it.  Not to mention a pushed shadow has nothing to do with DR unless it's from an exposure controlled comparison test.

It's not unfair to say DR for Canon sensors is lacking.  I've been shooting 7D since it first came out.  My aps-c Fujifilm X-E1 has MUCH better DR and shadow noise characteristics and that's in real world shooting.  Matter of fact that's what many 5DII/III converts say too.  I'm not saying 70D is not a good camera and can not take great picture buy If anyone REALLY cares about shadow noise they should investigate alternatives instead of performing this self gratification ritual.

I would have no problem if op changes the word "great" to "useable" in title though.
